FSDXA announce dxpedition to Kiritimati (Christmas Island/T32)
Last weekend at the RSGB’s convention, my friends at the Five Star DX Association (FSDXA) announced their next expedition to Kiritimati (Christmas Island) – T32 in the Pacific Ocean. The team aim to arrive 28th September, 2011 and depart 26th October, 2011.
The plan is to operate under the callsign, T32C. You can read more about the expedition at the official T32C site
I was very honoured to be invited to join the team, by Neville, G3NUG, though sadly I had to decline.
Having been involved on the inside of an FSDXA dxpedition before, I am absolutely certain that this will give DXers the very best opportunity to work T32. Hopefully, over the coming months, we’ll be able to bring more insights into the forthcoming operation.

QRSS beacon progress
Yesterday I finished building the QRSS beacon kit board. The keyer chip sends the wrong callsign but it that was no reason not to build the kit. It’s a very easy kit to build although there are no fewer than five toroids to wind which is a lot for such a simple project. Some people hate winding toroids though I find them easy to do and can’t see what all the fuss is about.
The only other slight difficulty with the kit is that the potentiometer for setting the output power has leads that are too big for the holes in the PCB. This is mentioned in the instructions, where it is recommended to use component lead offcuts to extend the originals. My junk box was supplemented a few months ago with a Maplin bargain pack of assorted potentiometers and lo and behold it yielded a wirewound trimpot of exactly the right value that perfectly fitted the PCB holes. So I used that instead.
When the board was finished I powered it up using my bench power supply and PM20 QRP absorption wattmeter. In the photo I have breadboarded a regulator from 9V down to 5V as I was toying with the idea of running the beacon from a rechargeable PP3 battery (the board will fit into a case I have which has an integral PP3 battery holder) and wanted to see how much heat the regulator would dissipate.
I found that I could get a maximum of just under 100mW from the beacon with about 120mA current drawn. This is a little less than the specification. The instructions suggest that a bit more than 100mW should be possible, but the shortfall isn’t enough to worry about. For longer battery life I will run the beacon at 50mW which draws a current of around 65mA.
To get the transmitter on frequency and set up the mark/space frequency shift I used my K3 and QRSS VD software. The signal, even on the dummy load of the power meter, was very loud which was helpful getting it into the ball park. I had to disconnect the antenna, switch in the attenuator and back off the RF gain to reduce the signal to a level where I could fine-tune the frequency and see what the signal would look like on the air.
And here it is, sending G4LIO! It’s a bit frustrating not being able to connect it to an antenna and put it on the air because of the wrong callsign. I’ve been promised a new chip and I practically snatched the post out of the hands of the postwoman but it hasn’t come yet. In the meantime I can think about putting the beacon into a nice box. Forget winding toroids, for me that is the hardest and least enjoyable part of any constructional project!

144-MHz SoftRock
144-MHz SoftRock Ensemble II VHF by KB9YIG and VE3NEA Rocky 3.6. Yup, that’s W3APL/B (off the back of the beam) and WA1ZMS/B in the same waterfall. How cool is that?! More later… This has many implications for many projects!

Wouxun go mobile with the KG-UV920R

Alerted by posts by Patrick, WA0TDA and Steve, GW7AAV, I see that Wouxun have announced an entry into the mobile rig market, with their KG-UV920R rig covering 144/432MHz.
Based on the coverage that Steve mentions in his post, there is FM receive from 65-220MHz – so this rig could receive on 70MHz too! In fact, reading the posts, I was wondering whether Wouxun will, in time, consider a 70MHz capable mobile rig.
The Wouxun portables have proved excellent and I am looking forward to hearing more about the mobile rig in due course.

Tuesday night tropo…
I didn’t spend too much time on the radio on Tuesday evening, as the cats were requesting entertainment again – which was a pleasure to provide! Being the second Tuesday of the month, it was the 432MHz Activity Contest and there was still some tropo around. The best DX for me was DF0MU in JO32 – which I was more than happy with. It was also good to work GD8EXI (IO74) – the first time I have worked GD from Longworth on 432MHz. Interestingly, like last month, he was at his strongest when I was beaming southeast. A reflection, perhaps? I was also pleased to hear some northerly IO93/IO84 squares which are less common for me.
Oh. And a special mention to the contester, whose callsign I will not mention, who when I called him first, he only got my suffix. No problem. He asked if I could give my prefix. No problem, I did. Then he proceeded to moan that he hadn’t got my full callsign! I seem to remember mentioning when I wrote the contest column in RadCom, that it’s best to be nice to the people who call you – otherwise they might not call you again. This gentleman won’t be hearing from me for a while, then!
Tropo seems to have faded down mostly now, although there was something weak on 145.650 this morning, either GB3PO or ON0WV – I couldn’t tell. Apparently the forecast for the weekend could be favourable for more tropo. Let’s hope so!

Technology failure
Olga and I went to a dinner party last night and the topic of how we have become slaves to computers came up. When I was a child, the science books promised that technology and automation would make our lives easier so we would work less hours and have more time for leisure. What a joke that seems now. We all work longer hours and the impact of computing and modern communications technology is that people now expect answers instantly instead of when you can get around to it. When I mentioned another promise of the computer age, the paperless office, the entire table fell about laughing.
Kelly, K4UPG writes that he had just spent six hours running updates, fixing the problems the updates created and figuring out how to install the updates that wouldn’t install automatically. His verdict: Computers Do Not Save Time.
The last couple of mornings Acronis Non-stop Backup has displayed a message that it was not running. Kelly’s post made me wonder if this was caused by a recent Windows update. I decided to do a System Restore back to last Monday, before most of the updates occurred, and lo and behold Non-Stop Backup is running again. I don’t have the inclination to spend six hours installing updates individually to find which one caused the problem, nor to ferret through forums searching for a solution, so automatic updates have been switched off for the time being. Having a working backup is more important than receiving fixes to problems I haven’t experienced and probably never will.
The trouble with computers is you have to spend too much time being your own support technician, time you should be spending working, playing radio or whatever the computer is supposed to be helping you with. Once upon a time computers were simple, reliable and never needed updating. What was the name of the operating system they ran? Ah yes, MS-DOS.

KN-Q10 SSB/CW 5W kit – US$280
Recently there was an interesting discussion here on vk2rh.com about some of the barriers to a wider takeup of the new wave of Chinese QRP or DIY ham radio kitset activity. One of the hurdles of course is language and the current lack of an English language user base to grow and deliver email support for kit builders.
Overnight Adam, BD6CR has made available an English translation of the construction manual for the KN-Q10 QRP kit designed by Ke Shi BA6BF. The KN-Q10 is a four band (3.5, 7, 14 & 21MHz) 5W SSB/CW transceiver kit.
Adam has also revived the Yahoo group China_QRP -
“I have made a decision to turn this yahoo group into a forum to support overseas Chinese kit builders and merchants. We will see more overseas kit builders and merchants joining.”
John AE5X posted a report about the manual translation earlier today. He also included a link to a discussion thread about the kit on the Chinese language HelloCQ forum. The photos here are sourced from the designer Ke Shi, BA6BF’s own postings and give some sense of the finish and quality of the project. There’s a large number of photos of the Q10 under construction on the thread.
John AE5X noticed the current lack of a schematic & parts placement diagrams and an operating manual for the kit even though this appears to be referenced in the translation. Certainly this version of the manual doesn’t offer the comprehensive ‘hand-holding’ guidance Elecraft, SWLabs or Softrock kit builders are used to. John sees no inherent problem with this – as long as prospective buyers are aware. I see this manual translation as an important first step towards opening up this exciting DIY/QRP activity to a wider audience.
Today on the China QRP Yahoogroup Adam has explained that he is selling the KN-Q10 kit for US$280 which includes air parcel delivery anywhere worldwide and that he accepts PayPal. If you’re keen to buy, it might be best to contact Adam via the Yahoogroup to identify the appropriate email address for that.
UPDATE 15 October: Adam BD6CR has already posted an updated version of the manual and it now also includes photos and links to the schematic diagram of the KN-Q10 and a Chinese language document with photos illustrating the modification to the encoder.
