A Second West Coast Lightwave Adventure

51km Path courtesy: https://www.google.ca/maps

Toby, VE7CNF, successfully inaugurated his lightwave station earlier this week, on Monday night, completing a nice two-way CW contact between West Vancouver (CN89) and Mayne Island (CN88). The distance spanned was approximately 51km (32 miles), crossing atop the western edges of Vancouver and then across the Strait of Georgia, the body of water separating mainland BC from Vancouver Island.


The details of Toby's homebrew lightwave equipment are described on his web site here and are similar to the station at this end ... also described in earlier blogs. This was the same path covered in my two previous lightwave QSO's with Markus, VE7CA, described here.

Monday evening's weather was clear and calm but at this time of the year, true darkness is a long time coming. With a full-moon just a few nights away, the sky never did get very dark it seemed. I set up my end of the path late in the afternoon, just in front of the house.

Accompanying Toby to the mountain lookout location were VA7MM, his YL VA7MAY and Markus, VE7CA who initially scouted out and found this nice site for our original lightwave contacts. Thanks to Markus who snapped a picture of the diehard lightwave crew!

One thing that I noticed on Monday night was the very loud QRM coming from the sodium vapor lighting used on the ski hills just above Toby's location. The resolution of my Fresnel lens was just not sharp enough to be able to isolate Toby clearly without also being saturated with the lighting noise ... from my end, the ski-hill lighting appeared just above his deep-red LED.

Although Toby's signal was very strong, the lighting hum was strong enough to cause some receiver front-end desensing and slightly modulate Toby's CW signal with a touch of AC ripple. I did not notice this hum when working VE7CA at the same location a couple of years ago. It's possible that there was no snow on the ski-hill at the time and the lights were not turned on.


Moving the receiver just a few degrees to the west made a huge difference, as the hummy background noise level returned to the quiet hush of a dark sky.

Toby's recording of my signal is much cleaner as there are no bright lights when looking towards Mayne Island. It is really interesting to hear the rapid fading, almost a flutter, on my CW signal, as the light passes through various levels of ever-changing haze above the water.


Midway through our one hour QSO, Toby reported that my signal had dropped measurably as had his signal on my end. Although I could see no obvious clouds in the path, I did notice a red glow out in the Strait that had not been there earlier. When I turned off my transmitter, the glow disappeared, indicating that there was indeed some low level haze that had crept up on us, and enough to cause some signal absorption on the path. Thankfully signal levels returned to normal, and actually were a bit stronger, about fifteen minutes later, when the haze thinned and the skies had grown a little darker.

Towards the end of our QSO, I had the chance to test out my #2 receiver. It was built so that I could do some NLOS cloudbounce testing here on the island, without having to separate my main system's transmitter/receiver pairing. At the time, there were no lenses available from the overseas manufacturer, so my quest for a suitable lens led me to a local 'bargain style' hardware importer (Princess Auto), who had a good supply of $5 lenses. The lens seemed to function well in my local tests but it had never been put side-by-side with the higher quality lens in my main transceiver. As it turned out, the $5 lens worked very well, easily detecting the 51km signal although it didn't sound quite as loud since the receiver I built for it was intended to interface with my laptop and lacked the additional audio amp I had built for the main system.

A final interesting observation was made, when on a whim, I placed a large cardboard shield over the bottom quarter of the transceiver's receiver lens. The signal strength didn't appear to change at all. I gradually blocked more and more of the lens but astonishingly, was still able to copy Toby's CW with all but a 1" strip of the lens completely covered! This would tend to indicate that we would be able to communicate with a very much smaller Fresnel or optical glass lens, such as a 4" or even a 2" inch magnifier. As I commented to Toby on CW, the possibilities for experimentation are endless.

All-in-all it was a very successful evening and the mountain-top gang seemed to enjoy the outing as much as I did, and ... the QSL is in the mail.


Hopefully there are other VE7's in or around Vancouver that might be interested in throwing a signal over this way some night ... I'll leave the light on for ya!

The Best CW training app for Android

Morse Trainer for Ham Radio

I'm always on the lookout for useful tools to help increase my copy speed and enjoyment of CW/Morse Code.  Training applications for beginners that teach letters and letter groups are great to get started but after you're making QSOs and copying at useful speeds those apps get a little stale. 

I recently wrote about using the "Morse News" RSS reader application for PCs. What I liked about Morse News was that it would send the text of news articles as CW.  I found it useful as a natural language trainer but I didn't like being tied to my PC during training.  

I wanted a similar application for my smart phone.


Just the mobile ticket to CW training


I'm not sure how I missed the "Morse Trainer for Ham Radio" app up to now but I've been using it for a couple of weeks now and really find it useful.


Morse Trainer in QSO Text Mode


Training Modes

This app has all the standard Morse Code training tools such as letter training, letter groups, callsign training etc. It also can send the most common 500 words as well as a random sample QSO training mode.  That's all great but what I really find useful is the ability to send your own text that you type or paste into the app and even... wait for it... an ebook reader!  

I must really be a geek but I find the ebook reader makes this a must have CW training app for me.  I converted some of my ebooks into plain text (using Calibre) and placed them in the CWTrainer's application folder on my smart phone.  I then choose the ebook mode, choose a book and it will send it as CW to me and keep track of where I left off.  I use this ebook reader mode to break the monotony of my long drive time.  

ebook mode

It's great fun to witness the expression of the person beside you at a stoplight hearing Morse Code pouring out of your car.  Priceless.

I keep the speed higher than I can comfortably copy so I'm missing some of what is sent. There's nothing like reading an action novel where you're missing half of what's going on. Did Tex get shot or not? I missed that word, hehe.

While this app doesn't read RSS feeds like Morse News application for PC's the text and ebook reader modes more than make up for it. The only bug to-date that I've noticed on my phone is that if I rotate the phone while it's playing it will reset where it was reading from back to the beginning. 

Here's a video from the application's author describing it's functions...


And here's a link to the application in the Google Play store.

https://play.google.com/store/apps/details?id=com.wolphi.morsetrainer

I have no affiliation with the maker of this application.  I just wanted to share.



That's all for now

So lower your power and raise your expectations

Hunting For NDB’s In CLE 206


This coming weekend will see another CLE challenge, this time in the LF band from 190 - 239.9 kHz.

'CLE's' are 'Co-ordinated Listening Events', and NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

One nice catch to try for is 'LU' on 214 kHz shown on the left. The 'LU' NDB is in a breathtaking location, high on a mountain meadow at the foot of the North Cascade mountain range. In spite of the towering mountain peaks to the east and to the south, 'LU' is well heard, being reported as far east as Massachusetts and as far west as Hawaii.
The antenna is a 100' top-loaded vertical with, presumably, an extensive ground system as this is a very large site. The transmitter is a 500 watt Nautel. 'LU' is about 20 miles north-east of the Abbotsford Int'l Airport, Vancouver's alternate.

From CLE coordinator Brian Keyte (G3SIA), comes the following reminder:

Our 206th Co-ordinated Listening Event is next weekend.

Do join in if you can. First-time CLE logs will also be very welcome.

Days: Fri. 22 - Mon. 25 April, Midday-Midday, your local time
Frequencies: NDBs from 190 - 239.9 kHz
PLUS: Normal NDBs on 'half-way' frequencies nnn.5 kHz
(from 190.5 - 999.5 kHz)

Both halves are for everyone to try.

Away from Europe many of the frequencies below 240 kHz are busy with
NDBs. In Europe there are very few there, but some DX ones might be heard from North America and maybe from a few other places.

The normal NDBs (not DGPS) which have carriers on the 'half-way'
frequencies (e.g. 284.5 DY, 333.5 VOG, 370.5 LB, 390.5 ITR, 433.5 HEN)
are scattered across Europe but there are very few of them elsewhere.
'Hot spots' are ENG and ITA.
These half-frequencies give comfortable QRM-free listening and probably
some good catches as a result.
America has only one or two (e.g. 381.5 SJX) but East and West coasters
might hear some DX ones.

We last used these 'rules' for CLE190 in January 2015.

Please send your CLE log to the List in a plain text email if possible
(not in an attachment) with 'CLE206' at the start of its title.
Show on each log line:

# The date (e.g. 2016-04-22, etc., or just 22) and UTC.
(the date changes at 00:00 UTC)
# kHz (the nominal published frequency, if known)
# The Call Ident.

Show those main items FIRST - other optional details such as Location
and Distance go LATER in the same line.
If you send interim logs, please also send a 'Final' (complete) log.

As always, tell us your own location and brief details of the equipment
that you were using during the weekend.

Good listening - enjoy the CLE
----------------------------------------------------------
From: Brian Keyte G3SIA ndbcle'at'gmail.com
Location: Surrey, SE England (CLE co-ordinator)
----------------------------------------------------------

(If you wish you could use any one remote receiver for your loggings,
stating the location and owner - with their permission if required.
A remote listener may NOT also use another receiver, local or remote,
to make further loggings for the same CLE).

Brian

These listening events serve several purposes. They:
  • determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date
  • determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range
  • will indicate the state of propagation conditions at the various participant locations
  • will give you an indication of how well your LF/MF receiving system is working
  • give participants a fun yet challenging activity to keep their listening skills honed

Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted there a few days after the event. If you are a member of the ndblist Group, results will also be e-mailed and posted there.

The very active Yahoo ndblist Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome.

If you are contemplating getting started on 630m, listening for NDBs  is an excellent way to test out your receive capabilities as there are several NDBs located near this part of the spectrum.

You need not be an ndblist member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 'First-time' logs are always VERY welcome!

Reports may be sent to the ndblist or e-mailed to either myself or CLE co- ordinator, Brian Keyte (G3SIA), whose address appears above.

Please ... give the CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.

Portable Ops 18/45: 20 Meters was good today!

I finally got a chance today to play on the radio – my first time on the air since the SKCC WES!  Much to my enjoyment 20 meters was actually playing nice for me!

I went over the local park near my office and got set up – it is a absolutely beautiful spring day here in Kansas.

Setup in my Honda Pilot – J-37 key to KX3 coax out to
31′ Jackite pole with vertical wire from a 9:1 UNUN
 – works great!

After tuning around a bit and not hearing anything, I decided everyone must be listening and nobody seemed to be calling CQ – so today I decided to only call CQ!

And the contacts began almost immediately….

AI4UL (6327) – Bob gave me a call from North Carolina with a nice 559 signal – he gave me a 569 report.

VA5CW (4326S) – Bill gave me a call from Saskatchewan Canada – and he was very loud – 599!  He was running 100 watts into a yagi, so I am sure that helped.  He dropped his power to 5 watts and I could still copy him very well.  We had a nice chat, and a nice two way QRP QSO!

KF7WJY (14522T) – Tim returned my call from Nevada, but we both had very weak signals 339 both ways.  It was a slug, but we managed to finish up the QSO.  Thanks Tim!

K2PAY (4304S) – Jerry was very weak when he first returned my call from Long Island, NY – 339 here in Kansas.  He gave me a 459.  QSB got the best of his signal when he was telling me his power, so I don’t know if he was QRP or not – I think he said 50 watts, but not sure. (update: a PM on the SKCC sked page Jerry said he was at 50 watts)

KG7VTO (14714) – Bob called me with a 559 from Pendleton, OR.  After reading his QRZ page, and looking at his SKCC number, I figured out he is a pretty new ham.  He just got his ticket fall of 2015 and joined SKCC in December 2015.  Bob had a nice fist and it was a pleasure to work a newer ham – glad you were bit by the CW bug Bob!

W4RMM (2471T) – last QSO of the day goes to Bill from Alabama!  He was pretty weak here in Kansas with a 339, and he gave me a 449.  We kept it short because I had to get back to work.

Thanks to all that answered me – you provided me a truly enjoyable lunch time portable operation!

What a fun day on the radio!  I picked up several new SKCC numbers towards my Centurion Quest, and just had a fun time with the J-37 key.

The map of the Reverse Beacon Network from my calling CQ today – pretty impressive!

DX Sense and Nonsense

Some notes about DX chasing from both sides – written by an operator who has over 19,000 contacts in 8 years from a choice DX location, and many more thousands from the U.S.

There is no doubt that chasing, and better yet catching, DX is a fun and rewarding part of the hobby of Amateur Radio. The game is to put as many different country entries into you log as possible. However, a few inconsiderate operators can make it difficult to impossible for everyone else. In fact, a few bad operators in a country can cause a DX station to avoid working a band when it is primarily open to that country or region as has happened to Italy and Spain, to name a couple of the worst in my experience.

Of course there are many well mannered and considerate operators in both Italy and Spain, but there are a seemingly growing number of rude and overbearing operators there who poison the DXing for everyone else. For example, as a DX station I have established that I will say “QRZ” when I am finished with the previous contact. I will guarantee that if the band is open to Italy or Spain there will be from 2 to 6 or more stations calling while I am still in QSO with the previous station. Their vocal minority is just as bad about ignoring directed calls from DX stations to other parts of the world. To be fair, other parts of the world, including the United States can be just as bad.

As a DX station, I want to make as many contacts as possible so that everyone gets a chance. I have enough problems with interference of all types that I may not copy you very well. IMPORTANT: If I want anything beyond my signal report, I’ll ask. If I didn’t ask, but told you my name then an appropriate response from you is ONLY 1) signal report and 2) name. Again, if I have time to ragchew, then I’ll give more information; and more importantly I’ll ask for more info from you. Otherwise, PLEASE NOTE, you are just taking up time that I could be spending giving one or two or three more stations a DX contact.

This ragchew rule applies double or triple to the small SSB “DX Window” on 75 meter SSB. If you are stateside (or elsewhere) and operating from 3790 to 3800 (*ARRL recognized); or from 3775-3800 (recognized by the rest of IARU Region 2 and all of IARU Regions 1 & 3) then you are in the SSB DX Window. If I want the weather in New England or New York then I’ll ask. If not, please give someone else a chance at DX. And please, do not hang around to ragchew with your East Coast or Southern buddies on 75 or 40 meters just because you have sunrise. We can still hear you farther west, and you prevent us from hearing the Pacific region.

DXpeditions are some of the worst violators of common sense and courtesy in my experience. Apparently the pure difficulty of the adventure is sufficient reason to believe in your own importance. The band plans seem to have been pulled out of a hat (being nice here)! NO DX station, no matter how rare as the right to the entire band. A number of recent Dxpeditions have been on 12 meters at 24.935 and other frequencies “listening up” or “listening up 5 to 20”. Put 2 or 3 DX stations on 12 or 17 meters and there was no place for anyone else ! Don’t break your arm patting yourself on the back….give me the whole band and I can make many thousand contacts as well!

Some other DXpeditions in the past have been almost as thoughtless. It is not uncommon for a DXpedition to call CQ on 3790 say, and listen up 5 to 10! Hold on there! That’s the entire *ARRL SSB DX window for 75 meters that one station is using. A suggestion for the future: Call outside of the window and listen to a SINGLE frequency inside; or call inside the window and listen above or below the window. Or better, tx and rx outside of the window. If your are rare DX, then we’ll find you!

I have personally had to “go split” when operating in the 75 meter window from a DX location when the number of callers on my frequency prevented calling stations from hearing me. It is not unusual for me to listen outside of the ‘window’, or even down at 3745 if that happens to be an open frequency. I do not find it useful to listen “5 to 10 up/down”. If I cannot make out some calls on 1 rx frequency, then I can seldom make them out when they are spread all across the band. To each his or her own, but it does say a lot to me about operator skill.

Ten General Rules for Maximizing Your Number of DX Contacts

  1. Listen first. If you do not copy the DX station, then you will NOT work them. By calling or tuning up on frequency you may very well make my LID list though.
  2. Listen for instructions from the DX station. Are they listening “up 3” or “down 5” or “up 5 to 20 — UGH!”? Or are they ONLY listening for Europe, Asia, S. America, or another area. Don’t call if you are not in the area of the “directed call”. (see #4 below)
  3. Do NOT call when they are working another station. Even a moron can understand that this actually slows down the contact rate for everyone! And, personally I do not take or recognize “tail-enders” who call before I have finished a QSO. I always say “QRZ” when I am ready. It’s just my way of trying to bring order to chaos. ***If you ignore instructions and I copy your callsign then I will NEVER put you in the log, except maybe IW0zzz RS 00 “Lid”
  4. This is a hobby. It is NOT life and death! *Truth be known, YOU are NOT that important to get into my log, no matter where you are and no matter where I am!
  5. As a DX station I have a listed QSL Manager for a number of good reasons. If you choose to ignore that, good luck on getting a card…ever.
  6. If you are a serious DXer you probably have Internet access and access to the DX Summit spots. Please do NOT call CQ on my spotted calling or listening frequencies. What are you thinking
  7. If you are on a DXpedition and have real-time access to spots, please pick a frequency that is NOT already in use. I really don’t care what you announced LAST WEEK as “your” frequencies. **This goes double or triple for your listening frequencies — DO NOT listen on frequencies already in use. You can also ask if the frequency/frequencies are in use. See number 4 above.
  8. Keep your calls short! Timing is more important than the number of calls. I hear many stations continuing to call AFTER I have given a report to a different station and am trying to get my report.
  9. Make sure that your transmitted audio is very clean; not too low pitched and not distorted! Turning up the mic gain to drive the ALC over scale will NOT make you louder!
  10. If you can’t or won’t play by the rules, prepare to be ignored!

In the famous words of late LA resident, Rodney King, “Can’t we all just get along?”

Good DX and good luck in ham radio!

It’s time cooler heads prevail!

The fans
Not wanting to have another Windows blue screen issue due to overheating I purchased two cooling fans for the PC tower. As mentioned in my previous post I did download HWMonitor that keeps track of the temperatures of my Hard drives, video card and CPU. Before the fans arrived I wanted to run the PC and monitor a baseline set of temperatures so I could see how the addition of the fans helped out to lower the PC temperatures. Before installing the fans I took some time to cut out the rear back board on the roll top desk
Snoopy checking on progress
so the hot air was able to escape. Before the fans were installed  my CPU temp ranged from 40C-45C, the video card was 55C-60C. After installing the fans I was pleased with the results. CPU temp was 28C-35C, video card temp's 38C-42C As mentioned I purchased two fans, I put an intake fan on the side panel and an exhaust fan on the rear panel. Ideally a front panel fan would be great but for some reason this tower does not have a front fan option. With adding the fans and opening up the roll top desk back panel the temp's significantly dropped. The high end temp's after the fans were installed was a result of the following programs running Win4k3suite, MRP40, N1MM, Google and also the power supply (which is in the same compartment as the PC). Next thing on the agenda is to organize a system backup for the hard drives because as we know Murphy is always just around the corner waiting for just that moment! At this point I am looking at software and option were to backup too.
Mood fans....:))
