WSPR signals propagate around the world and allow very weak signals to be correctly decoded. WSPR is some 12-14dB better than normal speed CW. If 10W gets through on CW less than 1W is quite enough with WSPR. My own 10m 500mW beacon, to a simple “nothing special” end-fed wire antenna has been copied on every continent in recent weeks, including Australasia and Antarctica.

The main bonus with WSPR is that all reports can be automatically sent to an internet database (WSPRnet), so anyone can see where signals are reaching and how well. Today though, the WSPRnet database has been in trouble, possibly due to being overloaded. It was not working the last time I checked but was working late this morning.

It's been a while since I've sit down to write down a few thoughts. I've intended on several occasions to sit down and write down my thoughts, but it seems some other priority asserts itself and I can't get the time to write. But not today.

So what's happened since I last blogged.

Tromelin Expedition FT4TA: The expedition team did a great job, making nearly all bands available with good signals, at least in South Texas. I enjoyed both working the expedition, to fill some band slots, but also the event. The daily news, conditions, the complaining, etc.... I worked them on 10m, 15m, 20m, 30m and 80m. All new bands except 20m. My practice, as I have written about here, is to try to work the expeditions, during the last days, QRP. I was not able to do that on this expedition. The pile-ups never really slacked off, which brings me to my point.

Now that many expeditions use Club Log and other online tools to post how many QSO's each caller has logged, the information is leading to much debate. I am on a particular reflector where an individual copied and posted the band scorecard for multiple individuals and berated them for making multiple band/mode contacts when so many needed Tromelin for an all time new one.

My thoughts on this one: As long as an individual doesn't dupe band/mode slots, working the expedition is fair game. If a DXer builds a station that is capable and puts in the time operating to work Tromelin on 20 band slots, why not. Telling him not to is like telling a guy with a Ferrari that he can only drive the speed limit.  If, for whatever reason, a dipole is all you have, you know that working rare DX is a tough proposition. Why should the capable stations be made to wait on those not so capable. In my early days of DXing, not working an expedition motivated me to improve my station, improve my operating skills, improve my understanding of propagation, etc... Failure is often life's greatest teacher.

DX-peditions can control this somewhat by limiting the number of bands they operate on, but those guys paid their money, why shouldn't they have all the fun they can.

Andamans VU4CB and VU4KV:  This team also did a nice job activating a pretty rare place, that from my part of the world, is difficult to work.  I was able to get QSO's on a few bands and was impressed with the operation. I was not able to work these guys on QRP either. VU4VB operated from a rare IOTA which I also chased. So, please all around on this one.

SOTA Activations: I did find time to get in four SOTA activations near my Santa Fe, NM QTH during November. I activated three peaks, along with Fred KT5X and John K1JD, southeast of Albuquerque, NM.

Thanks (again) to Steve G1KQH, these are Android apps for WSPR. I see they now include a TX beacon.

When it comes to the Bruce Kelley QSO Party and the rules involving the use of circuitry and tubes popular in 1929 or earlier, some have enquired..."Why 1929...what was special about that year in particular?"

Over the past few nights I've spent some enjoyable hours reading QSTs from the late '20's. It seems that 1929 was really the beginning of much that we have come to recognize, for all of our lives, as 'Amateur Radio'....but to answer the question, we really need to go back a few more years.

Prior to that time, and especially in the very early years, amateur radio seemed to have much in common with the 'wild-west'. Rules, if any, were difficult to enforce, as was licensing. May hams operated without a licence, choosing their own call letters. There was a lot of crazy stuff happening...bootleggers, broadcasting music and a general 'every man for himself' approach.

The establishment of the ARRL in 1914, by Hiram Maxim, was the beginning of what was to be a tough fight to educate and organize amateur radio activity in North America.




With the appearance of QST, in 1915, membership grew quickly and it soon became a sign of notability to be a League member. By the late 20's radio was thriving and growing at unprecedented rates. The U.S. amateur population grew from 16,000 in 1926, to 30,000 in 1932 alone. By 1938 there were 50,000 licenced hams in the U.S.

However, a federal judgement, in 1926, ruled the Radio Act of 1912, to be largely unenforceable, creating even more chaos amongst broadcasters. Things were getting somewhat chaotic in the amateur radio world as well as in the commercial field. The time was ripe for some serious changes.

In order to gain some control over this new technology and the chaos surrounding its usage, more so in the commercial field (ships, aircraft, broadcasting, telegraph), the U.S. Congress passed the Radio Act of 1927 thus giving more tools to the recently-established Federal Radio Commission, the forerunner of today's FCC.

Although the Radio Act of 1927 gave the FRC the power to enforce regulations, it came down to the international agreements hammered out in the winter of 1937 to make things happen. The  International Radiotelegraph Conference, attended by representatives from 72 countries, met in Washington, DC to grind out some international 'rules' since the growing popularity and surprising success of the 'shortwaves' was now of worldwide concern.

Much as we see today, the fight for radio spectrum had begun. The 172-page Washington document makes fascinating reading and in it we see the basis for many of amateur radio's beloved fundamentals.

It was here, that the new '1929 rules' were established and ham radio would never be quite the same...a very good thing.

The amateur's of 1927 didn't know it yet, but they would soon be deep in rebuilding their stations to meet the 'new requirements' of 1929!

Back in September I attempted to repair a Kenwood/Trio TR9500 UHF All-modes transceiver for a fellow club member. It had a faulty microphone pre-amp which I replaced and all seemed well but it had further issues with the receiver. Cutting his losses and wanting shot the owner sold it to me for the princely sum of £10.

I have had her back on the bench and initially couldn't find anything wrong. However in real use it become apparent that she was in fact profoundly deaf! Picking up test transmissions from the nearby FT857D or Baofeng outputting into a dummy load was one thing but it wasn't receiving anything else!

From the service manual and schematic I deduced that it could be the initial RF receive amplifier. It is a dual-gate mosfet (3SK76) It proved tricky but I managed to source a replacement on eBay and it was a simple job to replace once I'd extricated the PCB.

I can report it is now working and the video below shows it monitoring the GB3EE repeater in Chesterfield. From the coverage map I shouldn't be able to hear it but I can and reception has been marginal at best using other receivers but it repaired TR9500 doesn't have any problems.


I wonder if the rig has been subjected to a high RF field in the past this could easily have damaged the receiver amplifier and an induced RF into the microphone lead could have damaged the microphone pre-amp. It just seemed strange it having both faults.

Tuesday night is the last 432MHz UKAC contest and hope to use her in anger.

My Christmas present arrived last night. Being a patient and practical person, I waited until this morning to open it and as you can see, it’s the 2014 SKCC Club Key from LNR Precision. Click the image for a better look.

I had wanted to get this one in this calendar year as I’m not sure how much longer it will be available. I had picked up the Pro Pump NT9K Standard Version key while at Dayton this year and have been very pleased with its smooth action. This smaller version is just as well-built and enjoyable to use as the “Pro”.

I know that because the new key already has ten contacts to its credit…
