TX Factor, the UK’s first TV show dedicated entirely to amateur radio has certainly taken off. Episode 1 which launched back in February has seen over 22,300 downloads and the latest release has been viewed more than 7,400 times in the past 14 days. We’re extremely grateful to the amateur radio world for helping to propagate the news of this TV show and to help us achieve a large and appreciative audience. It’s made it all worthwhile!

If you’ve not yet watched an episode, then head over to www.txfactor.co.uk to see what’s on offer.

We’re always on the lookout for ideas for future show topics, so do let us know of any ideas we could consider for future inclusion.

Don’t forget to subscribe to our emailing list or YouTube channel to make sure you get notification of each new episode. Talking of which, episode 3 will be available in mid-May. The show features the famous Military Wireless Museum in Kidderminster with curator Ben Knock G4BXD and the king of kite aerials Roger Stafford G4ROJ. Mike Marsh visits the Exeter Radio and Electronics Rally and Bob takes a look at the new offering from FlexRadio Systems.

We’re currently building up a resource library of extracts from past shows which may be of interest to those who haven’t managed to watch an entire episode.

And if you can’t wait for the next episode, there is now TX Talk, a section of the web site where regular audio features on all aspects of amateur radio are uploaded. Right now, there’s an exclusive interview with FUNcube Project Manager Jim Heck talking with Bob McCreadie about the prospective changes to the FUNcube satellite’s transponder availability.

Agentschap Telecom – which is the Dutch version of the FCC – has decided to cancel the registration of my Dutch call sign PA2BX. And besides me also the calls of some 197 other Dutch radio amateurs who live abroad. Their reason being that since we don’t live in the Netherlands anymore we also don’t use the radio spectrum for which we need to be registered.

They already did so on March 12th, sent out letters to the operators involved on March 14 and then on March 19 informed the VERON, the Dutch Amateur Radio Society member of the IARU, that they were intending to do so. I don’t think I have to explain that I am very disgruntled with all this, and no doubt with me many others. At first sight it seems the AT doesn’t have any legal grounds to take this action and all is not lost, because I can always register again. But for now I cannot claim that I hold the call PA2BX and I cannot operate either in the Netherlands or with a guest licence in many other countries. These civil servants sure know how to waste time and money thinking of silly things like teasing us amateur radio operators.

…and another….and another.

My first ever serious outdoor QRP operation yielded two additional firsts, namely first Trans Pacific QRP QSO and first US CW QSO on 12 meters. KZ5OM a.k.a. K6III was the one who made it possible, and my “thank you” QSL card was mailed to him directly. I didn’t know that Jerry is very active within the SKCC or the Straight Key Century Club. So in his e-mail back he suggested me to join the SKCC, get on the sked page and have another QSO with him. Also because I would be very welcome there.

Always being obedient I filled out the form on the SKCC web site and a couple of hours later K9JP mailed me my life long SKCC number: 12107.
Only after logging on to the sked page did I understand what Jerry meant by being welcomed. Immediately some ops wanted a QSO with me and I got mail asking for skeds. I hadn’t even hooked up my J37 yet, so on Saturday I did and my first every SKCC QSO was with VK4TJ, another very active SKCC member. On Sunday Jerry was also on line and we had our second QSO, although this time not QRP.

Chatting with others on the sked page is lots of fun and the atmosphere is very relaxed there. For now I am only one of three SKCC members in Taiwan and I know the others aren’t very active, so it’s no surprise I am so popular. The SKCC is also very popular, something I did not know. I became member on March 27, with number 12107. As I write this it is March 31 and already 23 other hams have joined after me, brining the total to 12130 members (minus a handful of SKs). Adding almost 5 members a day is quite impressive for a club dealing with such an old communication system.

The SKCC is about straight keys. I have two: my trusted J37 and a Junker NATO issue key. Never liked the latter because of the clicking sound it makes when you release the handle. It is German quality though, and if I don’t start using it I will probably never start liking it. So off came the banana connectors and on went a 5.25 mm jack. Four years of postponing, but done in 15 minutes. But I do like my various paddles and switching between paddles and a straight key meant switching jacks on the back of my IC-7200. Not convenient at all. So on Sunday afternoon took out the materials I had already prepared a long while back and finally made the switching box I had in mind. A year late, but an hour of drilling, fitting and soldering later I had the job done.

So thank you Jerry, it’s all your fault. Because of our QSO I am now member of the SKCC, had a lot of fun on air, started using my Junker key and finished a project.

This is to let everyone know that Wednesday night, Joe Walsh WB6ACU is going to be co-hosting TWiT.TV’s HAM Nation with Bob Heil, Gordon West and Leo Laporte. Will be a blockbuster show with several in- studio guests. Joe will be introducing a new Contest/Dx segment anchor that is joining the show. Watch live and fasten your seat belt!

Most of the embarrassment has faded away, so I can write about it now. Having my Cubieboard up and running I went for the next step, connecting my TNC for APRS operation. The Cubieboard has a UART port, but the supplied cable was for a USB connection. I still had my serial converter from my Raspberry Pi and tried to hook it up to the Cubieboard. Either I made a short or some Volts went where they shouldn’t have gone, but all of a sudden there was smoke and that is usually not a good sign.

So now I have two empty cases on my shelf: one for the Raspberry Pi, one for the Cubieboard. Ah well, that’s life. Luckily these mini-PCs are not expensive, but to me also not cheap, so I will wait a while before ordering another.

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.

Hooked up the 137 MHz receiver to the Cubieboard on Friday night. Wxtoimg installed without a hitch, Cubian already put itself into the dialup group (necessary for serial access for ordinary users) and I was ready to go. NOAA-19‘s next pass was after midnight local time, so I went to bed. The next morning I was greeted by a rather garbled image of east Asia. Hmmm….thinking cap on. I checked the recorded audio file on another computer and it was messed up, so either Cubie can’t handle the input well or the input is not good. Back to basics and after feeding a very clean and stable 12 Volts to the receiver I had perfectly synced images. Because of recent storms I lowered the double cross dipole, so reception is not perfect. But with high passes I now can get some nice images, like this one….
