Earlier in the week, I noticed a handheld 50MHz FM transceiver on eBay for £6.99. I read a little and it turned out to be a converted Tandy/Realistic 49MHz handheld. Back in the late 1980s (I think), Practical Wireless ran an article by Peter Julian, G7PRO on how to convert one of these on to 50MHz FM.

There had been a follow up article by Mike Hadley G4JXX and by coincidence, the transceiver on eBay was Mike’s! Unfortunately, Mike didn’t have a copy of his article, although he did kindly send me a scan of the original G7PRO one. I’m sure I can locate a copy of Mike’s article.

The little transceiver arrived today and I wasted no time in putting a 9v battery in it! It works fine and transmits and receives quite happily on 51.510MHz FM. The original article suggests the power output is in the region of 50mW, but I think Mike’s modification is for a little more output.

Actually, my thought was not particularly to use this as a transceiver, although it will be fun to play with the low power and see how far it will go, but in the Es season, to use it as a monitor receiver in the greenhouse/garden and see if I can hear any Es on it.

As for the price, I think it’s provided £6.99 worth of enjoyment already!

Gerrit PA3BYA has created an interesting SSTV Security Camera with the Raspberry Pi.

I could see this set up in the doorway of a repeater building on a remote mountaintop somewhere. It would be priceless to see a vandal’s bewildered face!

Would that jibe with Part 97? 🙂

Jameco recently reached out to me to ask if I’d be willing to ask you about the type of amateur radio products you’d like to see them carry.

Like DigiKey and Mouser, Jameco is one of the larger electronics component distributors in the United States. They’ve taken notice that amateur radio is a growing hobby and that their current inventory selection may not be serving us as well as it could.

So, what type of items do you have trouble sourcing?

Antennas? Batteries? RF connectors? A wide selection of QRP and other types of inexpensive kits? Other components you’ve had to source overseas?

No idea is too crazy — they want to know what’s on your mind and what frustrations you have when trying to get the items you need.

Normally my projects take a long time to finish because I can’t find the right materials (I’ll dedicate a post on that later). But my “Shack-in-a-Box” project was done fairly quickly: only six weeks.

The box is an old German army issue box that my Junker straight key came in. Very sturdy and not too heavy.

I padded it with foam I got from a shop selling notebook batteries; the plexiglass dividers were left-overs from old cosmetic product displays. The little basket was a dollar from the local hardware store and the only thing bought new.

Everything but the antenna is in there: the KX3, LiPo battery (old laptop battery cells from a friend), the touch paddle and various cables. There are ear plugs and an old computer microphone with which I get very good audio reports. With this setup it takes me less than a minute to be operational and packing up is equally fast. This weekend is a long one in Taiwan because of Peace Memorial Day and I’ll be out on the coast doing my first serious stint of portable operation. If you hear me on air don’t hesitate to call me. 73.

Thanks for the sexy, royal blue aluminum finger pieces!  I removed the black plastic ones and put these on. Oh, and by the way, they also sent me a spare pair of black aluminum ones, too!

QRP – When you care to send the very least!

Out for a lunchtime walk yesterday, I decided to pop into the local bookshop for a browse, not particularly intending to buy anything.

However, in the ‘travel’ section, I came across a lovely little book called ‘Pocket Atlas of Remote Islands: Fifty Islands I have not visited and never will’ by Judith Schlansky. As I leafed through the book, beautifully presented, I realised that in a manner of speaking, I had ‘visited’ many of the islands mentioned through the medium of radio.

When we have a contact with a distant island though, it is easy for it to be just a tick on a list and very often we have little sense of what life is like there. This is where this book comes in nicely!

For each island, there’s a map – as well as a couple of pages with some background to the island. In fact, the entry for Annabon relates directly to amateur radio and the aborted DXpedition in the early years of the ‘noughties’.St Kilda’s entry was even sadder, describing the issues of infant mortality that had beset the island.

I only browsed a handful of islands last night, but for anyone who is interested in the big wide world out there, and I’m certain that includes many radio amateurs – you’ll love this book!
