I still have a vivid memory of the day I discovered (and bought) my first QST magazine. It was in February, 1959, and I had recently turned 11 years of age.

It seems I was doomed from a very tender age and, as it turned out, there was little hope of recovery.








It was a Friday night and I had gone with my parents, as we did every Friday night following dinner, to the Eaton's department store in downtown Vancouver.

Eaton's had a new and modern supermarket-style grocery store on their bottom floor which stayed open until 9PM. As my parents did the grocery shopping, I would take the escalator to the 4th floor magazine racks and on that particular night, spotted the fate-determining issue hiding beside the Popular Electronics, Radio-TV Experimenter, Electronics Illustrated, Radio News, White's Radio Log and other nefarious radio publications designed, in part, to lure the allowance money from the pockets of wide-eyed youngsters like myself, already beginning to show symptoms of the dreaded radio-bug.

I recall debating to spend my small allowance on the costlier QST (55 cents) or the cheaper (40 cents) Popular Electronics. I found the technical-looking cover too overpowering, bit-the-bullet, and shelled-out for the QST ... that extra 15 cents forever sealing my fate.

As I sat in the back seat of the car (a '53 Chevy Sedan), waiting for my parents to finish their grocery shopping, I browsed through the QST. In truth, I understood very little but was particularly captivated with the station photographs in Rod Newkirk's "How's DX" column. One photograph in particular has remained in my memory through all these years, that of a young-looking "HS1JN" at the operating position from his exotic location in Thailand, along with Newkirk's equally enchanting description ... powerful stuff for a young mind eager to soak-up all of this new 'radio' stuff.

HS1JN's homespun 40-watt sender and S-40 receiver function faithfully on 20 c.w. in Bangkok where the OM is an officer in the Royal Thai Navy's research lab. After warming up on a fast WAC, HS1JN now aims for WAS and DXCC honors.


A recent internet search turned up snippets of information about the young Naval Researcher, Jamnong Saowanna, now SK, who eventually rose to the rank of Captain in the Thai Navy and was later instrumental in legitimizing amateur radio in Thailand. Apparently, back then, ham radio in Thailand had been unsanctioned and not officially approved by the government. HS1JN's original QSL also shows up, in the collection of K8CX, shown below.

Note that it's the same card shown taped to the front panel of HS1JN's homebrew transmitter in 1959. The K8CX card, for a 15m CW QSO with W6FMK in 1969, shows that OM Jamnong was by then running 500 watts along with a Collins KWM-2 ... quite a step up, but not nearly as alluring as his 'homespun 40-watt sender' and Hallicrafters S-40 receiver.

After absorbing as much as I could from my single copy of QST, I began making weekly visits to the downtown library via bus, every Saturday morning, as it was there that I discovered I could peruse their huge bound collection of QST magazines, and borrow the latest issues, just for the asking! As well, they had a stockpile of colorfully-covered Radio Amateur Handbooks that spanned the past two decades ... it couldn't get any better.

It was at this time that I changed my listening interests from the international shortwave broadcasters and began listening to hams on my old General Electric tombstone, particularly on 20m phone on weekend nights, as the band would be open all night long ... monster Cycle 19 had just peaked and propagation was nothing short of amazing.



   Between the February QST and the old GE, I never really had a chance.

Both the Baofeng UV-5R handheld UHF/VHF radio and the Sainsonic AP510 APRS tracker come with interface cables with pirated chips. These are clones of Prolific USB/serial chips. Since Prolific has taken measures against this, only old drivers will work with them. That means that one has to stop automatic driver updates as explained on the Miklor site for the Baofeng UV-5R. The same is true for the AP510. This is a nuisance.

I got tired of this and got myself some USB/serial modules from Ebay based on the CP2102 chip instead. The cost was US $1.43 a piece so it should be affordable for anyone. I also got some clear heat shrinkable tube.

It wasn’t too hard to follow the instructions on the Miklor site. I ended up replacing the chip in the original Baofeng serial cable. I’m a hardware guy so I think it is a shame not to see the three LEDs for power, rx, and tx so I used my Dremel to make a 12×12 mm cut-out in the original case, and then I closed it by using transparent shrinkable tube. For a picture, see the top of the first image.

If it doesn’t work the first time, exchange the rx and tx connections and see if that works better. According to this site, the boards can be marked just opposite of what you might think.

The Sainsonic AP510 APRS unit has a cable that on first sight just looks like a standard USB cable, but it also contains such a chip. Here I made a completely new cable without any case.  It is important that 5 Volts also passes through as this is used for charging. The pinout can be found on the site of DJ7OO (use Google translate if needed). I enclosed the board in shrinkable tube which is transparent enough for the LEDs to shine through as seen in the bottom of the first image. The board with the fake chip is found in the middle. 

So now I have interface cables for both units that don’t require me to stop updates of drivers or any other special precautions and it is much easier to program the devices from any PC.

According to the following post, the US Air Force still trains a few individuals each year on Morse Code. Also this blog that this post is on is a cool SWL website if you are interested.

This month's Sky & Telescope magazine mentions an interesting study presented in a press release from the International Astronomical Union's 29th General Assembly held this past summer.



Frederic Clette (Royal Observatory of Belgium) and colleagues analyzed the past 400 years of sunspot records and found that the (previously believed) upward trend in solar activity is really a calibration error. They found instead, that solar activity has been relatively stable since the 1700s.

The IAU's summer press release goes on to say ...

" The Sunspot Number, the longest scientific experiment still ongoing, is a crucial tool used to study the solar dynamo, space weather and climate change. It has now been recalibrated and shows a consistent history of solar activity over the past few centuries. The new record has no significant long-term upward trend in solar activity since 1700, as was previously indicated. This suggests that rising global temperatures since the industrial revolution cannot be attributed to increased solar activity.

The results ... make it difficult to explain the observed changes in the climate that started in the 18th century and extended through the industrial revolution to the 20th century as being significantly influenced by natural solar trends.

The apparent upward trend of solar activity between the 18th century and the late 20th century has now been identified as a major calibration error in the Group Sunspot Number. Now that this error has been corrected, solar activity appears to have remained relatively stable since the 1700s

The newly corrected sunspot numbers now provide a homogeneous record of solar activity dating back some 400 years. Existing climate evolution models will need to be reevaluated given this entirely new picture of the long-term evolution of solar activity. This work will stimulate new studies both in solar physics (solar cycle modelling and predictions) and climatology, and can be used to unlock tens of millennia of solar records encoded in cosmogenic nuclides found in ice cores and tree rings. This could reveal more clearly the role the Sun plays in climate change over much longer timescales. "

The graph above shows the Group Sunspot Numbers (GSN) measured over the past 400 years following the new calibration. The Maunder Minimum, between 1645 and 1715, when sunspots were rare and winters harsh, is clearly evident.

I found this graph particularly interesting with regards to long-term affects on propagation as it illustrates the upcoming predicted Gleissberg Cycle, the 'cycle within the Cycle' ... a period of several weak 11-year cycles in a row and lasting from 80-90 years ... great news for low-frequency fans but not so good for 6m diehards. 

Maybe we'll get one more humdinger before it arrives!
