WTB: Power Supply/Modulator for Viking 500
Good day folks.?
I just obtained a Viking 500 RF deck that over time was separated from its power supply/modulator unit.? It is a long shot, I know, but this group is probably my best chance in finding one.? Even an incomplete unit will be considered.? I guarantee I will bring it back to life.??
?
Thank you.

Re: Need Information on a 'Johnson MATCHSTICK Multi-band Vertical Antenna'
¿ªÔÆÌåÓýJohn,? it's ironic to me that you posted your question just days after I mentioned the Johnson Matchstick to a couple of buddies in an email. When I moved to northwest Illinois in 1986,? there
were still three electronics parts stores operating in Rockford
Illinois, and like most they'd been around for years and at one
time at least had sold ham gear.?? Having started to collect
boatanchors I made the trip to each, hoping of course to find a
Viking Desk Kilowatt in some dusty back room, but of course that
didn't happen.?? However one store (whose name I can't recall)
said the only piece of radio stuff they had was - you guessed it
- the control box for a Johnson Matchstick antenna just like
yours!? It was on a high shelf and the guy said it was probably
only there because it wasn't worth the effort to climb up and
move it.? I asked if they had the rest of the antenna, but he
said the box was all they had, and I suspect that if it was in
inventory, the outdoor components could have easily been
mistaken for junk.? Or if it was installed on the shop as a demo
antenna,? it probably wouldn't have lasted past the next roof
repair.? In any case, the Matchstick evidently did not sell well
for EFJ. Sorry I can't be of any real help as that's the only time I've seen any part of the Matchstick and only recalled it last week while reminiscing about the radio supply stores we used to have.? It wouldn't be difficult to make your own relay-switched base loading coil that could be controlled by it, but there are probably better antenna options today. 73, Bob W9RAN

Re: Free For USPS Postage: Valiant HV Transformer and (2) HV Chokes
Hello Tad!

There was an announcement a while back (which appeared genuine) that ARRL wouldn¡¯t be accepting new individual licensee new email aliases but would continue to offer forwarding for existing users and would be accepting creating @arrl.net aliases for club licenses ¨C a good idea since ¡°who should get club email¡± so often changes with club officer changes. The club announcement is here: If you¡¯ll do an Internet search for ¡°ARRL email forwarding not working¡± or similar language, you¡¯ll find many instances of outages over time. Perhaps this is just another one of them. In any case, I never used @arrl.net other than to try to avoid some spam harvesting of my ¡°root¡± email. Given the number of spam emails I get these days, even with a meticulously set up spam filter, that really didn¡¯t make much difference in any case! We¡¯ll see what happens next! 73! Mike/ K5MGR PS ¨C I did recently get rid of one major spammer whose emails had a provision for ¡°Changing email addresses? Update Here.¡± I kept updating them from my email address to no@... <mailto:no@...> after a couple of weeks it dropped my ¡°spam count¡± by about 40 email messages a day. A major spammer operates with source address range 128.245.x.x ¨C appearing to have ¡°leased¡± that range or a part of it from Salesforce in San Francisco.

Transcrypt Transpeater III
I used to have a copy of the specs and user guide of the Transcrypt Transpeater III but I no longer have it. We used them in the fire service back in the day. Does anyone have an idea where I might be able to find some information on this particular piece of equipment? I spend hours on archive.org and there is some old archives of the websites but no product. I'm searching for anything relating to it, anywhere from an electronics diagram to the piece of equipment itself.
