is a very good thing, but can be bad at times.  My buddy W3BBO describes it as an “obsession” or an “addiction”.  I’d have to agree with him there. Once you get your first taste and get hooked, there’s no turning back. Add QRP power to the mix and,  if you’re addicted to challenges – stick a fork in you, you’re done.

The bands were alive with signals again during lunchtime today.  But yet, I only worked two stations. My addiction got in the way. I worked Laci HA0NAR in Hungary, who I have worked many times before. I also worked LY10NATO, who asked me to spot him, as he was calling CQ without many takers.  Being in the car, away from the Internet, I didn’t have that luxury.

My downfall came when I heard TX6G on 12 Meters. He was LOUD. 599+ loud at times.  I immediately thought, “Wow! THAT loud, here’s my chance to work them QRP.”.  Not today, Grasshopper, not today.

Undoubtedly, if I wasn’t so hard headed, I could have worked at least three or four more stations in my limited time allotment.  However, my stubborn Polish side got the better of me, and I did a Don Quixote, and chased a windmill. 

The windmill won.

My daily routine, I start my day with CW on 14060 KHz. I listen for for activity. The last few days I worked OH9XX/P on 20m, I was using 5 watts. Yesterday UA2FAI, I was using 1 watt. Also worked RG3R with 1 watt but with JT9 on 10m. Of course all with the Yaesu FT817 and my end fed wire. Today we have nice spring weather. Sunny but a little cold about 1,5 C now at the moment. Yesterday also good results with WSPR into the USA with 500mW on 10m.

This is PART 3 of the project “Arduino Frequency Display For a Kenwood TS-520S HF Ham Radio”. This part covers 0.9 volt 38 MHz signal amplified into Schmitt triggered NAND gate for cleanup before going to a divide by 8 ripple counter chip then finally being cleanly counted by the Arduino using multiply by 8 math function to restore counts to 38 MHz. All parts: (PART 4), (PART 3), (PART 2), (PART 1)

Thanks for joining!

Ten Meters was busy after I got home from work – plenty of signals.  I heard TX6G but they were kind of weak, so I decided to check 15 Meters.  They were louder there and their pileup wasn’t quite as busy as on 10 Meters.  So, I started sending my call, with no luck. After a bit, I noticed their signal was starting to fade. Not wanting to lose them, I decided to go QRO and bumped up the power to 75 Watts. Bingo on the first call at higher power – TX6G is in the log for a new DXCC Entity. The group is there until April 1st, which is a week from tomorrow – so I will try throughout the week to try and get them via QRP. That’s a tall order, but do-able if the pileups get smaller as the DXpedition draws to a close.

From there I went back to 10 Meters and listened more than anything.  I heard quite the few JAs and tried calling a few, but 5 Watts just wasn’t cutting it.  Then, I heard a fierce pileup for VP2V/SP6CIK.  I managed to bust that pileup with 5 Watts.

I was amazed at the ferocity of that pileup.  While the British Virgin Islands are an easy hop from the US, I guess they are a rarer entity from Europe and Asia.  I heard quite the few JAs being answered as well as a lot of European stations. Whoever was behind the key was handling the pileup methodically and precisely. Very good pileup management and very good pileup discipline.  I only heard a few “UP”s from the Pileup Police.  All in all, it was a well behaved group.

I didn’t go out to the car at lunchtime today, as winter has returned for a brief visit. It was 27F (-3C) and I just wasn’t in the mood to freeze.  Tomorrow we’re supposed to get anywhere from a dusting to 3 inches (7.5 cm) of snow.  BUT, by Friday and Saturday, it’s supposed to be back up near 60F (16C). That’s the only good thing about late March snows in New Jersey – they tend to disappear fast.

I guess the old Mark Twain quote about the weather in New England holds true for New Jersey, too. If you don’t like the weather in New Jersey, just wait a few hours. It will change – especially this time of year.

Trying to find my way around

Each morning I catch up on my blog reading and on a few blogs that I read LED lighting seemed to be the order of the day for illuminating the shack. I have been up early the last few mornings to see what is on the air waves. I did not find much and decided to work on my contest code I use Morse Runner, this is a good program that adds a very nice contest atmosphere to the operator. A problem became very apparent as I was using the program and it had nothing to do with the program. My keyboard skills were rusty and the lighting in the morning  here at VE3WDM is very dim so cheating and trying to see the keyboard proved to be very frustrating. I really have no problem with the letters or the numbers but it was the F keys I was having problems with. The Morse Runner program uses the F keys for such functions as call repeat,

That's better

exchange repeat and so on. I was really messing up the F function keys because in the low light I just could not see my keyboard. I was getting very frustrated and on two mornings I just closed the program. Then remembering the blogs were I read about LED lighting I went out and purchased an LED lighting strip. It was super easy to install on the roll top desk and it seemed there was a spot just for the low profile LED strip to be placed. I was not sure if this was the ideal place for the lighting strip (lighting up the operating area and keyboard) It turns out that when the natural light went missing and the LED strip was powered up……all is well at VE3WDM and no QRM from it either.

Digital Solves All Your Problems? OK, I admit, that’s pure click-bait. In this episode I talk with Bruce Perens K6BP. Some of you may recognize that name, and maybe not have even known Bruce is a ham. Out there in the real world, Bruce is known for being one of the founders of the Open Source Software movement, and he remains an evangelist for the idea. Here in Ham Radio, he’s turned that focus to things like CODEC2, FreeDV, and the HT of the Future (put some mental reverb on that as you read it).

What we’re talking about begins with the ARRL’s FCC petition to update our rules regarding digital modes to get rid of the reference to Symbol Rate, and replace it with a simple 2.8 kHz bandwidth limit (on HF) into which you may stuff anything that’s legal… BUT, they retain the cw/data – Phone/Image distinction. I just spent a few quality minutes on Wikipedia trying (again) to understand symbol rate, and I don’t get it. But I do get bandwidth.

Our discussion progresses to more on CODEC2 (a free, open-source CODEC for high-quality, low bit-rate voice transmission), FreeDV (a free, open-source program for using CODEC2 on digital voice) and that HT (HT HT HT).

But it’s that 2.8 kHz bandwidth idea that’s got a lot of ham’s undies in a knot. The worry, as I understand it, is that with an “anything goes” 2.8 kHz digital policy, digital will proliferate across the bands, causing interference to analog modes (SSB, CW). And the analog ops won’t be able to tap the digital ops on their RF shoulder and say sri, OM, QRM, pse QSY, tnx. WinLink2000, a fairly wideband and often automated digital mail system, is frequently the focus of their displeasure, as it can tromp on a cw QSO without recognizing what it’s doing (if I understand the argument correctly, and I don’t claim that this is either a complete and correct analysis of the issue).

In the program, Bruce and I recognize the potential problem. We might not think it’s likely to be as serious as some hams think it is, and we don’t have a solution, other than to note that QRM is a fact of life. But it is something worth discussing, and I’d like to have that discussion soon on another episode of HamRadioNow. I’ve got a few suggestions on guests to talk to about it, but I’m open to more (be quick).

We think the ARRL is taking a baby step with this proposal, in that it retains what we think is an artificial distinction between bits that make text, and bits that make image and voice. But last time the ARRL tried anything like this, about 10 years ago with their “Regulation by Bandwidth” proposal (a far more sweeping plan that would have divided the bands into segments that permitted stuffing whatever fit into 200 Hz, 500 Hz, and 3 kHz bandwidths), a large part of the membership got very unhappy. They still are.

So expect the topic to come up in the near future, and periodically for a while, because this won’t have a quick fix. But I don’t think it’s a good idea to hold back progress on future modes because they may cause some trouble with our current modes.

Several months ago I built an UNUN, like the one I use for my portable ops antenna, but this one was going in my attic.

I finally had time this weekend to get this thing installed in my attic.  I cut a piece of wire 30′ long for the radiator.  My shack is in the basement, and one wall is the garage wall.  So I drilled a hole at the bottom of the garage wall, and in the ceiling of the garage.

I then ran my coax from the basement up into the attic – very easy.

Then came the fun part, walking on roof trusses to get the wire installed.  Pretty easy, and luckily it is still cool outside.

Once installed I went down to the shack and hooked up the KX3 to the antenna.  It tuned up nicely on 40 thru 10 meters with the internal tuner.  So I put a quick CQ on 20 meters and was spotted coast to coast on the RBN – success!

About 11:30 pm on Sunday night I had time to get down to the shack again and see what was going on.

As soon as I turned the radio on I heard W1AW/5 (NM) calling CQ with no takers.  So I threw my call out and he came right back with one repeat on my call.  We exchanged 599 and it was fun.

I then spent about another hour messing around with FLDIGI and WSPR – with no success.  More to report on this later….these modes are all new to me, so there is a pretty big learning curve.

So now I can actually have some ham radio fun from home!
