[ARC5] [Milsurplus] "What's Old is New..."

Wed Aug 9 09:24:07 EDT 2017

Keep your eyes open, RF-350Ks get sold for $300-500, working, without the power supply. Without power supply they are 12 volt rigs. If you get a less expensive one which doesn't work I would be happy to help you with it, I've resurrected a number of them.

There is also the added benefit that the MRC-108 was not capable of secure operation that makes it just about useless in a tactical role.
> Don’t get me wrong, I am not disrespecting the KWM-2A but I have worked on them in the past and own one now that I use on twenty meters and the three mentioned difficulties can be easily overcome by a trained operator they are a real problem for people who have never had to deal with such issues.
> The Harris URC-119/RF-350K is a good example of what a modern HF transceiver looks like, direct keypad frequency entry and no tuning. I have a Harris URC-94 as my main radio in the shack today because I have not been able to find a URC-119 that I can afford yet and have been running my GRC-106 in the field for a while now and there is no substitute for direct frequency entry. Have to stop and think every time I use the KWM-2 where I am.

It looks like the Soviet type equipment could not interop with NATO equipment. My MRC-108 was surplussed in 1995 or so by the Ft. Hood DRMO. Inside one one of the storage box there was a pamphlet with instructions in Arabic, French and English. The system was poorly repainted painted sand color  (Maako paint quality).

We had no problems with the URC-119's even though we were routinely sand blasted by frequent Shamals...  And yes, HF CW was used in Desert Storm (I was one of the operators)....We used it for a backup and it worked just fine...

A couple of retired Collins Radio Company employees were "drafted" to "check out" the equipment before it was airlifted to the Gulf States.  I have been led to believe that one of the former Collins employees went along with the equipment to insure that it worked after deployment and to teach the military personnel how to operate the KWM-2A units.
