The USAF used a pile of them as well, on the flightline, as well as alert
crew radios.

Ray, don't forget the Systems Saber line of handhelds. IIRC they were built
for the Marines originally. They are an absolutely bulletproof handheld and
I think a secure encrypted version went for close 5 kilobucks back in the
90s. They are almost throwaway now, nearly fallen off the "eBay radar". Now
the Astro Saber handhelds go for cheap and the Systems Sabers are tough to
find.

I got mine nearly fifteen years ago and they were about 100 bucks each then
and I could still buy new nicad packs from Tessco at the time. 
Haven't looked in a while but I'm guessing it would be hard to find new
battery packs any more. But I recall reading somewhere they had one of the
best front ends on a handheld if not the best of all time, and I can vouch
for that.

the TW-100. Included in that lot is a new 100 Hz Synthesizer M5 in its
anti-static wrapper. I removed it from the wrapper and it does show the
5.120 Osc Adjustment so this is probably what you are looking for. It has a
green sticker on it with date 3-10-92. The M5 has been in storage here about
20 years. I no longer have a TW-100 to test it in so it is as-is. $75.00
plus shipment to your place.

Manual says I should have 2,8 VRMS.  I've changed the oscillator and buffer
transistors to no avail.  DC voltage seem OK.
