BLT+ Balanced line tuner at Excalibur

Another portable test of the BLT+ tuner

KX3 operating on internal battery.  What a fantastic portable rig.

I took the BLT+ balanced line tuner out to the Excalibur antenna site to try it out on the doublet antenna that we put up last Saturday.  This was the first test of that antenna (40m and 80m using a common feedpoint).

I didn't have much time today and after the first QSO it started to rain so I packed up and left before getting as much documented as I would have liked.  I apologize for not recording the actual tuning process and the subsequent QSO.

BLT+ connected to open wire line (under the gloves) going to ta 40m Doublet at 65ft
I had the KX3 operating using its internal batteries and outputting 2w. I was running 2 watts because that is the most efficient PA mode for the KX3.

I used the BLT+ to tune the 40m/80m doublet.  Balanced line antennas perform better with a tuner designed for balanced line and this was a good test for both the tuner and the new antenna.

I quickly matched the doublet using the BLT+ using the lowest impedance setting which is also the most efficient.  I was glad to see that the BLT SWR LED indicator is bright enough to be seen in direct sunlight.  I was wondering about that but you can definitely tell when it dims even in direct sunlight.

Performance

After quickly tuning up I sent my call two times and was promptly answered.  The other station was running a Flex 6500 into a KPA500 and a OCF Windom at 50 feet. 

He reported me as 559, while he was a 599.  He was running a new KPA500 amp at 500w so we were a bit mismatched on power.  

Interestingly the difference in 2w and 500w exactly matches the 4 S-Unit difference in our reports if you do the math (each increase in an S-unit requires quadruple the power).

Paul AA4XX kindly snapped some pictures while I was listening to the other operator.  This is the Excalibur antenna site but the shack is outside the photo. 

The Doublet's feed line has not been brought to the shack yet so I was just sitting under the antenna.  The open feed line is running along the ground for a bit which certainly didn't help the signal but we haven't installed the posts to carry the feed line over to the shack and I was too lazy to move the chairs far enough away to keep the feed line in the air.

In the foreground is some saw-grass common on the NC coast.  I'm not sure why it's growing this far inland.

Here is a brief video showing how the BLT+ is connected to the Doublet...


Summary

The little BLT+ performed great with both balanced line antennas I've tried.  It is easy to use and allows me to use my KX3 with balanced feed line antennas now.  I encourage you to build the kit from Pacific Antenna / QRPKits.com .

That's all for now

The N3ZN Iambic CW Paddle

Behold… mechanical beauty

N3ZN ZN-QRP Iambic Paddle (sporting my new call sign)

I re-entered the amateur radio hobby in the summer of 2015 after a bit of a hiatus.  To get my General license in 1996 a Morse code proficiency test was required.  At that time I had purchased a cheap MFJ practice key and a used version of the ubiquitous Bencher BY-1 paddle.  My Bencher was in reasonable shape but I just never became comfortable with it.  It always felt a bit imprecise to me and I wasn’t happy with the width and size of its paddles.

1 Watt and a Wire… in the Attic

You can't always get what you want, but you try sometimes...

Recently I've dialed my normal 5 watts down to 1watt (one watt, singular) for all my contacts.  To throw some water on the fire I've decided to use my attic antenna which weaves all around my metal ductwork and electrical wiring.   Mostly this was to prove a point to myself but it may be enlightening to deed restricted hams that they can use a qrp radio and an attic antenna successfully.

Key lineup... Palm Single (paddle), Vibroplex Bug (circa 1970s), Kent Hand key

It only seems pointless until you try

Calling CQ with 1w QRPp into a poor attic antenna isn't as pointless as it would seem.  I didn't have to wait long when calling CQ before I got an answer most of the time.  

Now am I going to bust a pileup with 1 watt ?  Possibly not but I think that my assumptions about both how much power I need and how big an antenna I need are usually out of proportion with reality.

1 mighty watt

My assumptions are often incorrect

I made QSOs on 30m, 20m, 17m and 10m this morning all at 1 watt.  The solar conditions report was not really fantastic, especially for 10m.  Yet 1 watt through the attic antenna bagged the only DX I heard on 10m.  I had a couple of other multiple exchange contacts on 20m, 17m and one good old fashioned 25 minute long ragchew on 30m where I received a 599 report for my one watt from Bob (NR8M) in Ohio.  Admittedly, Bob was booming in and we had good propagation to each other.

Video

The recording below was number 4 or 5 this morning.  I wanted to post this one because I was working another QRP station in Arkansas (K5EDM) and we did NOT have great propagation to each other.  He was running 5w while I was running 1w so it was QRP to QRPp.  In the video you can see that I'm using some of the KX3's tricks to pull the signal up because there was a lot of QSB and noise (note the GEOMAGNETIC FIELD UNSETTLED in the solar report).  

I had the volume maxed and was using the RF gain control mostly.  I eventually had to turn on the preamp which really washed me in noise but I dropped the RF gain more and eventually switched in the APF (audio peaking filter) which performed magic on this contact.  Often I find that APF doesn't help but this time it made a big difference.

Can anybody hear me

Calling QRP CQ - Inconceivable


My 80m OCF Dipole has been a surprisingly good antenna and I've made contacts with it on all bands except 6m and 160m.  Based on my past experience trying to tune up short antennas on 160m I really hadn't considered trying to use this Windom for 160m.  But through some email exchanges with another ham in Illinois who had recently put up a 160m antenna we decided to try a scheduled QSO on the top band.  So it was time to give the Windom a shot on 160m.

Amazingly my 80m Windom / OCF Dipole has  4.5:1 SWR native around 1.8 mHz and it matches easily with a tuner across the entire 160m band.  That was a surprise. 

I tossed my mighty 5 watts call out at 1810 kHz not expecting much...

Within a minute of calling CQ I had a faint QRP station from Maine tried to work me.  After about 4 tries I finally copied his call correctly but then lost him.  Immediately another station called me and we exchanged the niceties of signal reports, location, rigs and weather.  I received a nice 579 report for my 5w and I gave him a 599+ report for his thundering kilowatt station.  He needed to work my County so I was glad to be able to provide him with the contact.  Following that call the former QRP station from Maine was back in there and finally we worked each other.  We had a nice QRP to QRP QSO on the top band.  He gave me a 549 report but he was using a 400 ft beverage receive antenna.  I was struggling a bit more to copy him through local QRM on my side and a less qualified receive antenna and reported his signal as 339.

Those were my first two contacts on 160m using CW.  Who'd have thought my cloud burner antenna and QRP power would get me such quick results on the top band.  I just figured no one would hear me.  
So how do you know if and where your signal is getting out ?

The Reverse Beacon Network

I had to quit right after those two QSOs but when I later checked my email the original station with whom I'd planned the scheduled QSO reported that although he had not heard me he said I was getting out and sent me a link to something called the reverse beacon net showing a couple of stations that were hearing me on 1810 kHz.

You mean I can find out in near realtime if and where my signal is being heard by an automated system? No way!  That is cooler than a Ronco Pocket Fisherman.  Recall that I'm relatively new at this stuff and this may be old hat for a lot of you.  But the ability to toss out your call and in real-time check where your signal is getting to just warms the push-pull final transistor in my heart.

The Reverse Beacon Network can give you the last 100 reports of your station. So I took a look and saw some of my weekend activity where I was shooting some fish in a barrel (I mean working contest stations) and there were beacon reports of my call from such places as far South as the Antilles and as far West as Utah.
Map of the last 100 reports from Reverse Beacon stations of my call sign
Color coded by band

So the reverse beacon network report tells you what station heard you, the frequency, the signal to noise ratio (higher is better) and your word per minute (wpm) speed.  

It even includes a speedometer

Being a new CW dude my word per minute speed is of interest to me.  Most of my QSOs in the past week have been at 15-16 wpm.  I'm using a Vibroplex Bug I received last weekend and have slowed it down with a home-made weight attached to a drywall anchor pressed on the end of the pendulum.  I found it interesting that some beacon stations reported me at 19-23 wpm.  I looked at the time and the frequency and realized that the higher speed was from my first on-air QSO using the Vibroplex Bug with N4HAY before I slowed it down with my junk box bug tamer.  
My brief speed key session with N4HAY
So if you are using a manual key and don't know what speed you are sending just check out a beacon to see what speed they are reporting.

Summary

This reverse beacon stuff has been around a while. So unless you're a newbie like me you probably already knew about it.  But if you haven't used before it's very cool, especially with regard to knowing how your QRP station is being heard. Are you making it 1000 mile per watt?  Is your antenna propagating East, West, North or South.  How and where is the skip?  This answers many questions that I had been wondering about as I'm operating.  A shiny new toy, just in time for Christmas

So that's all for now.

So lower your power and raise your expectations

Don’t Bug OUT when hearing a Vibroplex semi-automatic key

Vibroplex Bug Morse Keys 

Since starting to work CW on-air a few months back I became familiar with the sound of other operators using Vibroplex Bug telegraph keys.  I have been curious to try one of these semi-automatic keys even though I know that they are not recommended for new operators.
Vibroplex Original Semi-automatic Bug
The Bug uses a sprung pendulum to automatically send DITS.  The action of moving the lever to the right starts the pendulum in motion and it creates evenly timed DITS automatically.  DAHS are created by manual timing moving the key to the left.  Using the key requires quite a bit more practice that using a straight key or paddles. 
The Vibroplex semi-automatic Bug is considered a manual key by the SKCC (Straight Key Century Club) so it counts in SKCC contacts.
Used Bugs in decent working condition can often be had for under $70.  This one was advertised as being "un-used new in box".  Indeed, when I received it, it still had the shipping bumpers on the main spring and still had shipping grease.  The glue on the nameplate had deteriorated and come loose and there was significant oxidation on the parts.  This bug is a few decades old but that doesn't matter because Vibroplex bugs haven't changed much in design since 1907.  The history of their creator, Horace Martin is interesting.  He created the bug to help deal with his own degraded sending ability due to long hours operating a straight key as a renowned telegrapher.
Horace was a professional telegrapher so he designed the bug for professionals who sent at speeds well above what is normally used in amateur radio.  The slowest speed this bug can send DITS without modification is about 25wpm and goes well above 40wpm.

As a beginning CW operator you will generally be well below that speed in your copy skills and likely your sending speed as well.  But when experienced hams work you with a bug they will slow their DAHS down to your speed, however without special added weights there's not much they can do to slow down their DITS to your speed.  This gives their FIST a unique sound.  The DAHS are sent slowly but the DITS are zinging by.  When you first hear this style your brain will not know how to interpret what you hear but give it some time and you will learn to copy them.

You can slow the Bug down by adding weight to the end of the pendulum.  An inexpensive method is to wrap the weight with some solder.  I've wrapped mine to bring it down to about 22wpm.
Wrap the pendulum weight with solder to slow it a bit
Here is a little video letting you hear a bit of the cadence of the bug.  Now I just received this thing today and I practiced with it for about 30 minutes before making this video so I'm no bug operator for sure but it will give you some idea of the bug "swing"...


Here is a video running through the keys to see if learning a Vibroplex messes up my ability to use a paddle with an electronic keyer

Learn Morse Code – All the Cool kids are doing it

Amaze your friends / Confound your enemies

Ok so maybe all the cool kids aren't doing it... who wants to be a cool kid anyway?  They have issues.




So whats up with all this beeping?

Morse code is fundamentally a method of encoding every letter in the alphabet plus numbers and punctuation as two pieces of data. Two sounds actually, one 3 times longer than the other.  If you were to speak the two sounds out loud one would sound like DIT and the other DAH.  That's it.  That's all you have to know.  Two sounds, one 3 times longer than the other. There, and you thought this would be hard?  Pah!

Beep Beeeeeep -- There you have it... Morse Code.  Any questions?

Why is it called Morse Code?

Samuel Morse was a painter. Yep, a portrait painter. Ah, you're thinking he must have painted numerology into his portraits thus developing a "code".  Nope, nothing so cloak and dagger. The motivation for his invention was due to a sad event in his life.

While he was painting a portrait of the Marquis de Lafayette in Washing DC he received a message delivered by a messenger on horseback telling him that his wife at home in New Haven Connecticut. was sick. He received another message the following day informing him that she had died. He immediately returned home but she was already buried. Morse was heartbroken that his wife had been ill for days before he could receive a message. He decided to explore a means of long distance communication. Along with his assistant Alfred Vail they developed the primary language used in telegraphy across the world and collaborated with other men to design the mechanism to deliver messages in Morse Code over long distances.

The rest is, as they say, "history"

Why learn Morse code?

Morse code has been in use for over 160 years, the longest of any electrical coding system. Morse code is still transmitted by some automated aviation beacons and the US Navy still (?) employs the code when using signal lamps for radio silence operations.  Submarines have signal lamps in their periscopes.  Morse code is still taught by the Airforce at Goodfellow Air Force Base in Texas.

So that's cool but the main reason to learn and use Morse code is for use in amateur radio.  CW (continuous wave) communication is the most energy efficient mode of electronic wireless communication that doesn't require computerized encoding/decoding.  In the case of Morse Code the human is the modem.  CW mode allows amateur radio operators to communicate world wide at QRP (low power) and QRPp (very low power) levels. CW's power density and simple transmitter/receiver requirements provides for simplified station operations and ideal emergency operations.  You can carry a small, battery powered radio and some wire in your backpack and talk around the world.  

CW is small but powerful

CW uses between 100Hz and 150Hz of bandwidth compared to 2400Hz - 3000Hz used by phone modes.  That makes it about 20 times more efficient, or put another way, your signal to noise is improved by a factor of 20 over phone.  It's also easier to copy (interpret) a CW signal down in the noise than a spoken voice. 

A 5 watt CW station can run off of AA batteries or a small solar panel and communicate locally, say across the county coordinating emergency services via ground wave, or to other continents for message exchange.  QRP radios operating CW are the ultimate fallback mode for emergency communication.

But the real reason to learn Morse code is that it's fun and unique.  Learning it can be the mental equivalent of climbing a mountain and, most importantly, all the cool kids are doing it.

So you want to learn "the code"

Usually your first exposure to Morse code will be some chart that shows you what combination of DITs and DAHs (or dots and dashes) make up each character.  This might encourage you to listen for the individual DITs and DAHs to learn the code.  But it's a trap.  There is a part of your brain that counts and another part that handles language.  The part that counts will quickly hit a limit as to how fast it can count and interpret what you are hearing.  The part that handles language is designed to interpret and transmit communication at incredible speed but the language part of you brain works with sound.

Thus you have to approach learning Morse Code as a language by the way it sounds.  An "A" sounds like DIT DAH.  Say it out loud a couple of times, go ahead, don't be embarrassed, the people around will simply think you've finally lost it and pull out that power of attorney they've been keeping in the drawer.  Ok are you saying DIT DAH? If so you are hearing the letter A.  Congratulations, you just learned the first letter of the alphabet in Morse Code.

A "C" in Morse Code sounds like DAH DIT DAH DIT.  It has a beautiful rhythm when you listen to it out loud.  Go ahead and shout it out, you've got nothing to lose at this point.

So, if you have toyed around with learning Morse Code and have some visual chart with dots and dashes. Shred that chart right now.  Go ahead and do it.  I'll wait... Did you shred it?  Ok let's proceed.
Carry On

Methodology

There are probably as many ways to learn Morse Code as there are days of the year but I'll address the two ways I learned it.  First, a wrong way, then a right way.

One wrong way

Morse Code was a requirement for my General amateur radio license in 2006, but I only had to prove copy skills at 5 words per minute.  Someone recommended a set of tapes that employed mnemonic phrases to memorize each letter.  Basically each letter "sounds" like some phrase. I'm going to tell you one of the mnemonic phrases as an example but please immediately erase it from your memory because it takes a long time to un-learn this method. The letter "Y" sounds like the following phrase said out loud "Why did I die?"  OK, now just imagine you've memorized some phrase like that for every letter of the alphabet and punctuation mark.  Now every time you hear a letter in Morse Code one of these phrases runs through your head and you have to let it run its course before the letter pops out on the other side of your consciousness. You can understand how crippling this becomes when the speed goes above 5 words per minute.  Trying to counts DITs and DAHs hits the same wall.

One right way

I'm not going out on a limb to say there is only one right way to learn Morse Code so I will say that what follows is "One right way" to learn the code and it is working for me. 

Learn the code by its sound. Learn the code by its sound. Learn the code by its sound. Let's review: Learn the code by its sound.

There are lots of different software applications out there that will teach you the code by the way it sounds.  Many employ two well established methodologies; the Farnsworth Method and the Koch Method.

Farnsworth Method

Learn the sound of the letters at the full target speed you wish to be able to copy.
Keep the speed of the letter spacing (silence between the letters) to be at your current learning speed to give you thinking time.  I.e. you're letter spacing may be set at 8-10wpm to start out with while you're actually learning the characters at a target speed of 20wpm.
This method is recommended by the ARRL and is implemented by many applications used for Morse Code training.  This allows you to learn the sound of the letters at the full target speed you want to operate at.  If you learn the sound of the letters at 13wpm then you will find yourself stuck there until you relearn them at a higher speed because you're learning to recognize sounds, not DITs and DAHs. Our brain has an easier time of slowing a sound down than speeding it up so if you start at the target speed the slower speeds will work themselves out.  I started with a target speed of 18wpm and I am kind of stuck there right now, while learning the sound of the characters at a higher speed to progress.  I wish I had originally chosen 20wpm as my target speed because in my experience that is a common speed in many QSOs.

Your training should also incorporate the Koch Method which directs the order in which you learn the letters, numbers and punctuation and determining when to progress to the next element.

Koch Method

Begins with just two characters (K, M). Once strings containing those two characters can be copied with 90% accuracy, an additional character is added, and so on until the full character set is mastered.

Code Trainer

I looked at a number of different code trainers.  I tried PC applications, mobile device apps and internet based applications.  I live in a very internet connected place and I nearly always have access to the internet.  I don't always have my PC with me but I do usually have access to a guest PC or a mobile internet capable device so I chose a website that has a training application  that incorporates both the Farnsworth and Koch methods and would keep track of my progress.

Learn CW Online  http://lcwo.net/

Learn CW Online is a really nice Morse Code tutor. You create a login for it to keep track of your progress and settings for character speed and effective speed.  It has multiple ways to train so try the different ones out to find out what works best for you.  I used the Koch Method CW Course which is accessible after you log in.  It starts out with two letters and keeps track of your accuracy, making suggestions as to when you should add an additional letter. There are 40 lessons in that course which include the alphabet, numbers and punctuation.  I've read that other people really like the MorseMachine application on that site.

After you've gone through all 40 Koch lessons you may still have trouble with a particular set of characters.  Use the Code Groups application to work through your stumbling blocks.  Lastly natural language training is provided in the plain text training application which sends real sentences at your speed settings.  You can also paste text into the convert text to cw  application and download the resulting MP3 to practice off-line.



Listen to real QSOs

Machine learning is patient tutor and the best way to get started but after you have learned your letters and numbers and a comma you should incorporate copy of real on-air QSOs into your learning regimen.  

Copying real QSOs will teach you a couple of things.  First, you'll realize that people by and large do not send perfect, machine generated code.  Much of the slower code you will hear on HF is being sent with straight keys, bugs and cooties.  Some of these manual key operators will send with timing that is, let's say, creative.  At first you may be dismayed that you can't copy a single complete word from some of these operators but give it time and your brain will adjust to the unique cadence used by many manual key operators.  Some manual key operators pride themselves in their distinctive style of sending and there are a few operators that I recognize before they ever send their call just by the unique style of their FIST.  I'm not encouraging you to emulate that style because it is in essence communicating with a thick accent but you should begin to become familiar with hearing the code sent by these folks because you will eventually have QSOs with them.  Even operators using paddles and electronic keyers won't sound like the machine generated code because their letter and word spacing will vary, or in some cases, be nearly non-existent.  I describe some operators FIST as sending one extended prosign (no space between the letters) for an entire transmission.

Secondly you'll begin to start copying the myriad of abbreviations and prosigns and jargon used during QSOs that exists nowhere outside of amateur radio CW conversations.  As you come across new "words" that you copy.  Circle them until you begin to recognize what they mean.  Some of the abbreviations are standardized but many others are just shorthand and sometimes unique to a particular operator or region.  You'll also start to become familiar with the way operators communicate their goodbyes which vary greatly in content, abbreviations and length.  Some goodbyes in morse code seem to take as long as the entire previous part of the QSO.  In other cases the conversation ended and you didn't even hear the door slam behind you.

A word about Morse Code translators

There are a number of Morse Code translation programs available for mobile devices and computers.  My recommendation is to NOT use them when you're learning to copy.  They will become a crutch and in real QSOs they tend to not be accurate (excepting for CW-Skimmer) and will get you distracted from trying to actually copy the code yourself.  Where they ARE USEFUL is in translating your own sending (see below).

Pace yourself and have fun

The most important thing is to have fun.  No one makes their living as a telegraph operator any longer and the code is no longer required for a license. So don't stress out about learning the code or push yourself too fast.  This is just a hobby and hobbies should be fun.

If you can, practice a little every day. When you start, if you're like me, you will find that you mentally tire out after about 15-20 minutes so don't push it.  You are exercising a part of your brain that hasn't had to work much since you learned to talk, and that may have been a few years back.

Different people will learn at a different pace but I haven't met anyone that doesn't make progress if they keep plugging away at it a little every day and if you miss a day no big deal, just try not to let it lapse.  You are building a new muscle in your brain.  You may also hit a couple walls along the way where you don't seem to progress but it's coming.  Just be patient.  Morse Code is not fast food.  

Morse Code is a mode for folks that don't have a lot to say but want to take a long time to say it; so why rush?

Sending Morse Code

Learning to send code is a different skill than learning to copy.  Your ability to send good code is primarily formed by your ability to hear good code.  You have to be able to hear the code as properly timed sound bites in your head before you can expect to send properly.

Personally, I'd recommend that you hold off practicing sending code until you have worked through all the lessons and can properly copy.  Your brain needs time to memorize the proper sound for each letter.  If you start practicing too soon you could develop poor timing habits that will take time to correct.

When you are ready to practice; try sending something like a news article.  Or write a few sentences about your weekend and practice sending them.   At some point you should begin practicing simulated QSOs. The SKCC beginners corner has a good sample QSOs to practice.  When I started real over the air conversations I had my QSOs written out with blanks for the other station's call-sign.  I didn't try to stray far from the text in the beginning since trying to think of what to say while spelling it in my head and remembering the sound for it was just too much for my puny brain.  But after a couple dozen real QSOs the nervousness starts to wear off and you can think and send.

I have had a little over 300 CW QSOs now and while that is still a relatively small number easily a 3rd of them have been lengthy ragchews lasting over 20-30 minutes so I've spent a lot of time "off-script" from the standard exchange.  At this point I don't have to concentrate much on what I'm sending, it just comes out.  I only have to think about spelling long words.

When you practice I recommend that you record yourself and then go back maybe a day later and see if you can copy what you sent.  You will think you're doing great until you listen to yourself.   Then you will practice sending more carefully! 
Remember the golden rule. It's better to send good code than receive.
Another useful practice tool for sending is a Morse Code Translator but as stated previously only use a translator to work on your own code sending.  Don't use one to copy in real QSOs or you will become dependent on it.

What kind of key

Of course there are different opinions on whether to learn to send code with a straight key or a paddle with an electronic keyer.  They each have their merits and detractors.  I wouldn't recommend starting with a cootie (sideswiper) or bug, they introduce too many variables for a beginner.

The video below discusses some difference in learning to send on a straight key versus a paddle...


Straight key

Straight Key (manual key)
Straight keys are simple, inexpensive and can work with many inexpensive practice oscillators such that you don't need a radio to practice sending.  The disadvantage of straight keys is that your reflexes are entirely responsible for properly spaced DITs and DAHs in addition to intra-character and word spacing.  The advantage is that after some practice they become an extension of your arm and simply repeat what you're hearing in your head.  I personally started with a straight key and still like to use one for the majority of my QSOs but it's a personal preference.

Paddle with electronic keyer

Paddle -- requires electronic keyer
A paddle works with an electronic keyer. The disadvantage of a paddle is it requires additional equipment and that you will be learning a different reflex from the actual code that is in your head. I.e. when you send an I or an S or an H you are not reflexively sending the DITs that make up the letter but are instead training yourself how long to depress the paddle for the string of DITs.  This is a new skill and doesn't directly correspond to what you hear in your head.  The advantage to using a paddle with an electronic keyer is that the keyer will send perfect length and ratio DITs and DAHs every time so your reflexes don't have to be as quick or precise.  Also it requires far fewer movements of your hand to send code with a paddle and you won't tire as quickly as you would with a straight key.  I won't go into the concept of squeeze keying here.  For now don't worry about it.


As to the specifics of using a paddle with a keyer:

The electronic keyer may be external or built-in to the radio. If it's external then it will normally have a speaker or mic jack to provide a sidetone allowing you to practice without connecting to a radio. If you don't have an external keyer and want to practice with a paddle you will need a radio with a built-in electronic keyer and be aware how to set it to not transmit for practice. Usually this is accomplished, strangely enough, by turning off VOX (which stands for voice activation) in the radio's menu. Keyers have a speed setting and weighting. Speed seems pretty obvious. Weighting is the ratio of the length of the DIT to the DAH in length. In general the weighting should be set to a higher value when you are sending at a slow speed and set to a lower value as your speed goes up.

Your first on-air QSO

So now you've practiced your copy skills and you can confidently copy on-air stations at the speed you wish to operate.  You have also been practicing sending and when you listen to a recording of yourself it actually makes sense.
You are ready to venture into your first, heart pounding, fight or flight response on-air QSO
If you can find a local ham who already knows the code to practice with that certainly makes for a less intimidating first foray.  If you don't know anyone ask your local 2m repeater club if they have any CW Elmers who are within ground-wave distance of your station to work with you.  Barring that ask someone in a forum and see if you can schedule a QSO but scheduling QSOs is often hit or miss based on propagation.

If none of those options present themselves then just go for it on-air.  Find an ongoing QSO that you feel you can copy or is moving just slightly faster than you can copy.  Copy the call-sign of the station you can best copy and wait for them to sign with each other (they will each send their 73s / 72s and send a DIT DIT at the very end).  Then call that station.

AA4XX AA4XX DE N4PBQ N4PBQ N4PBQ PSE QRS KN
If you've been listening to regular QSOs you'll recognize the form above.  The repetition of the other station's call is to get their attention.  You repeat yours for their benefit.  The PSE QRS is asking them to slow down and the prosign KN means you're asking only them to respond.  Have a prepared QSO text ready in terms of what to send.  The SKCC beginners corner has a good sample QSOs.

Here is a sample QSO from when I was just venturing onto the air.

What is going on in the radio

As far using Morse Code in radio communication  is concerned; a transmitter modulates a 100Hz to 150Hz wide signal called a Continuous Wave or CW at a particular frequency.  The time the signal is transmitted corresponds to the length of time the trasnmitter key is depressed.   When listening on a receiver you hear a tone whose pitch is determined by your offset from the frequency of the transmission. If you are listening exactly on the same frequency you will hear nothing because there will be zero Hz offset.  So most modern receivers offset the receiver frequency above or below the signal and offset their own transmit frequency by the chosen offset.  So if the offset is 750Hz you will hear a 750Hz tone if you are exactly on frequency with the other station.  Confusing?  Good, you're well on you way.

Summary

So you know as much as I know now... well admittedly I don't know a lot, I'm just learning this stuff myself but I can almost promise you that it will be fun if you have some patience with it and you will meet some of the nicest people in ham radio... well meet them virtually, well meet them as monotone beeps, well meet them as decoded signals sent from one human computer to another human computer, but trust me; after you've had a 15 minute conversation with them and only exchanged your names, where you live and what the weather is you'll feel as though you've known them your entire life.

I've jotted down my thoughts on the ins and outs (mostly outs) of learning Morse Code as part of my QRP Ham Radio adventure.  I think it is relevant enough to visitors to the Ham Radio QRP website to make it a static page available from the main menu:

Rock ‘N Radio — QRP Style

Operating QRP
Can mean operating from a "Quiet Restful Place"

I had the day off today and it was a beautiful morning.  I decided to spend part of it at Lake Wheeler Park in Raleigh, NC operating QRP from a stone bench under a tall oak tree.
rock 'n radio
I was operating the Elecraft KX3 from its internal AA batteries for the two hours I was there running 5 watts and it worked well.  I had brought an external battery but didn't need to connect it.

I threw a line over a tree using a throwing weight.  I hit my mark the first time, untied the weight, tied on the end of the antenna, and hoisted the 31 foot end-fed up exactly where I wanted it with the feed point a couple of feet off the ground.
31 feet of wire end-fed by a 9:1 balun.
A kite string winder holds the throwing line
A metal stake with a bit of rope anchors the balun and the other end of the rope

Another view of the end-fed with 9:1 balun, stake and coax
The 20 feet of coax serves as the counterpoise so hookups couldn't be simpler.  The KX3 simply has the coax attached to one side and the morse key and headphones in the other.
QRP operating position
The morning was very pleasant, if a bit windy, clear with a temperature of 55 F.

The KX3 will match the end-fed wire on about any band other than 160m but on 80m you could likely throw the radio farther than the signal travels.  The KX3 auto tuner is pretty amazing and I believe it could tune a piano if you hooked it up correctly.

I worked stations on 20m, 40m and 30m.

I called CQ on the 20m QRP calling frequency (14.060) and had a brief QSO with a lot of QSB (fading).  I didn't hear much activity that early in the morning on 20m so I dropped down to 40m and worked the QRP calling frequency (7.030) and had my call answered right away.  After that QSO another station jumped in there calling for a specific station so I moved on.  40m was busy.  Every time I thought I'd found an open frequency someone would jump back in or if I called QRL? I'd get an R R.

So I went up to 30m, and had a very nice long ragchew that lasted nearly an hour.  The internal AA batteries on the KX3 were getting a workout operating at 5w for that entire time but I never saw the transmit wattage drop below 5w and when I finished up the internal batteries still showed 9.8 V  The cutoff is 8.5 V so there was plenty of juice left.  I may just stop carrying the external battery on these brief jaunts.

My long ragchew was with a station in GA about 400 miles away and he gave me a report of 599 so I was thrilled with 30m this morning. Coincidentally, this end-fed antenna, balun, coax-counterpoise combo is nearly resonant on 30m and I've had some of my best reports when operating this portable antenna on 30m. 

Key wise, I was using the Palm Single Paddle.  It is a great little key when you don't have a table to operate from and you don't want to strap something to your leg.  I get strange enough looks from passer-by's without them wondering why I have some mechanism strapped to my thigh and the Palm Single is very inconspicuous.

The Palm key has a clip-on, magnetic base which I use to temporarily attach it to my clipboard when I'm not sending.  When I'm ready to send I simply pull it off the clipboard and hold it in my left hand. As I noted in an earlier review of the Palm Single Paddle it can be used as a straight key if you turn it on its side.  The long ragchew I had on 30m was with a gentlemen who sent me his SKCC number in the first exchange so I quickly turned off the electronic keyer in the KX3's and turned the Palm Single on its side.  That station sent me a nice compliment on my straight key FIST; so the little Palm Single key can serve duty as a paddle into a keyer or (in a pinch) as a straight key.  I far prefer to use my Kent Hand Key if I'm operating manual key but it's too big to bring along for portable operations and I can't quite picture myself trying to hold onto the giant Kent Hand Key with one hand whilst operating it with the other like I can the Palm Single.

The Palm Single Paddle works great in portable operating positions
I made a silly little video of my trip to the park...


So enjoy some nice fall weather if you still have it and have a Rock 'N Radio adventure.
What could be finer than to be in Carolina in the Mooo-oor-ning

Enjoying the last nice days of our Fall... birds singing and morse code beeping
That's all for now...

So Lower your power and raise your expectations
