Birthday card co-incidences

Today I celebrate my 64th birthday, although it is only 5 minutes since I was 18, so be warned: time passes very quickly and speeds up as you get older!

One strange thing today was some of the birthday cards. When in Oxford a few weeks ago my XYL bought me a card for my birthday, from the OXFAM shop, with the title, "Instructions are for wimps" showing a man operating 1920s radio gear - very apt for a radio amateur. Well, blow me down, I got the same card from 3 people! If you want one to send to your friends, they have plain insides so can be used for an occasion, they come from  www.cathtatecards.com.

Now, to my mind, the operator looks a bit like Julian G4ILO. Perhaps it was his grandfather!

Surplectronics - useful source

Steve G1KQH has just pointed me to Surplectronics who supply all manner of electronics parts at VERY reasonable prices. Several of the crystals they stock are just 25p each and 50MHz clock oscillators (packaged, complete) just 99p.

Tenbox 10m AM crystal

Although I've not finished off the Tenbox 10m AM transceiver yet- too cold in the workshop and too many Christmas preparations! -  I have been looking around for some low cost crystals that would be suitable for the transmitter. Ideally, I was looking for a low cost source of HC49 crystals on 29.05MHz but have not found any. Then I spotted that the German QRP-shop has 29.000MHz crystals at a reasonable 5.5 euros. I may order a couple so I can complete a pair of QRP 10m AM transceivers. I have used QRP-shop before and they give good service.

The Tenbox may not get finished until the New Year now as we have family here for the next 10 days more or less. When there are 4 grandchildren around, amateur radio takes a back seat, especially as my operating shack is used as a bedroom for the 3 and 5 year olds.

JT65-HF QSO

It is some while since I last tried JT65-HF mode for a QSO, so this evening I had a go on one of my difficult bands in the evenings (because of the local noise level) i.e. 80m. A short listen and reply to DK6CS resulted in a very solid QSO both ways with QRP. I must give this a go on the higher bands, although I find the 1 minute TX/RX slots rather slow, with a minute to know if your response to a CQ has been successful. Still it works with weak signals and allows me to work stations that might not otherwise be possible.

Countries worked this year

There is no way I would call myself a DX chaser at all, preferring to build simple kit and use it to experiment rather than "countries chase" as such. Nonetheless, I thought I'd look back through my logs to see how many countries I'd actually worked on each band during 2012 with my 5W or less QRP.  It is quite surprising to see how many countries I did NOT work and also how few QSOs I had on some of my less favourite bands. At the present time it looks like I worked 46 different DXCC countries with 1-5W SSB/CW. Most QSOs were SSB. By far the most countries were worked on 10m. This season I did not do my usual sport of seeing how many countries I could work on 6m and ended up only working 6 countries this year! Some years I'd worked almost 50. Notice also how few countries I've worked on 160m - 12m: hardly any!

Not included in this list are all the WSPR spots I have received and given around the planet. There are several stations/countries with which WSPR spots have been exchanged that have not been worked in 2-way QSOs.

There is no doubt in my mind that had I concentrated on DXCC with 5W it would have been possible to work well over 100 entities this year even with my very compromised antenna system and 5W or less. Maybe one year I'll give DX working a real blast just to see what I can work, but really I prefer to leave this to others in the main and enjoy other aspects of our wonderful hobby.

Selling my Elecraft K1

For some years I've had the Elecraft K1 transceiver that I made. It covers 40, 30, 20 and 15m with a built-in auto ATU.  This is a nice little CW radio, but I rarely use it, preferring to use home designed kit on MF and 10m these days. It has always been used at home and is in as-new condition.

This afternoon I fired it up, using the coax feeder to my 10m halo as a vertical and tuned this against my central heating ground using the internal ATU. It is a far from optimum antenna and suffers from QRM from my central heating controller's SMPSU right next to the feeder on RX.

RBN spots with my K1 today (intermittent operation)

Conditions were not great but several reports were seen on the Reverse Beacon Network (see above) and half a dozen QSOs are in the logbook on 7MHz and 10MHz (in DL, I, EI and LX) in not a lot of actual operating time: we had neighbours around for Christmas nibbles and drinks most of the day!

I really ought to think about selling the K1 as I don't use it enough to justify keeping it.  Ahead of my move next year I should be doing more de-cluttering as well, HI.

Good review of the Argonaut VI by K4SWL

Although I was critical of the price of the Ten-Tec Argonaut VI QRP transceiver at $995, I see it has received a rave review on the QRPer blog today from K4SWL who was one of the beta testers.  In his opinion it is better than an Elecraft K2 with a receiver that is likely to be highly rated in the Sherwood tests.

As he points out, this is not really a "trail-friendly" radio. Rather, it is a small radio designed mainly for home use where its excellent performance, size (a bit smaller than the K2) and good ergonomics make it ideal. He praises the simple uncluttered controls and ease of use and the nice flywheel tuning knob. But, overall he rates it and likens it to a miniature Ten-Tec Eagle with superb DSP performance and RX dynamic range.

The lack of 60m and 12m and an auto-ATU disappoint me, as does that high price tag, but it does look like this is a very capable little radio. It is just such a pity that it is so expensive. It will be very interesting to see a side-by-side comparison against the KX3 in the coming months.

Now if only Father Christmas would bring me either a KX3 or an Argonaut VI, HI.

472kHz WSPRing (now QRT)

It is now clear that the issue of my NoV for today's date was an error, either with OFCOM or the RSGB and that there was, sadly, no intention of releasing the band earlier than Jan 1st 2013. So, I have now gone QRT on the band again until the new year. I question why an NoV should be needed at all: why not just release the new band in the UK to all full licence holders and save the time wasting and paperwork chasing!

In the few hours of operation with my antenna very wet and lossy, so the ERP was around 10-20mW only at best, results achieved were very promising.

472kHz WSPR TX results today (10-20mW ERP)

Reports of my WSPR signal were received from 4 countries with the best DX being from Germany and the far NW of Eire.

I'm now back on 500kHz WSPR for the rest of the evening.

472-479kHz NoV received

Today I received my 472-479kHz NoV via the RSGB website. The NoV for 5W eirp (about 20dB more than I can run!) seems to indicate that the new band may be used by NoV holders immediately judging by the date of issue.

There is some confusion as the OFCOM website says:
"However, as a result of the World Radio Conference, under Agenda Item 1.23 amateur radio has been given an alternative allocation, on a secondary basis, of 472 479 kHz. We propose that Full Licensees should be able to to apply for an NoV to operate in this band from 1st January 2013. Application can be made online at http://www.rsgb.org/operating/novapp/nov-472-479-khz.php" 

My official OFCOM NoV says applicable from Dec 20th start date so I am allowed to operate from today unless told otherwise later by email or phone from OFCOM. This may be pedantic, but they should have checked before sending out the form.

My first WSPR reports have been received from PA3ABK/47 at around -24dB S/N with my ERP currently around 10mW only (too much wet on the antenna). Also received a report from G8HUH (250km) and PA3FNY (360km).

It now seems that the official 472kHz NoVs issued this afternoon (mine was this morning)  now state a Jan 1st 2013 start date.  So, am I legally operating I wonder? If the world ends tomorrow, at least I've got a few 472kHz reports in the log, HI.

10m WSPR today

Today my 200mW from WISPY beacon was not enough on 10m to get any reports. So, I went up to 5W with the FT817 and managed a few reports this afternoon. Conditions were not good. Nonetheless reports came in from North and South America and from Germany.
