[MRCA] MRCA Digest, Vol 184, Issue 18

Sun Aug 18 21:45:38 EDT 2019

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.

> I looked through the parts I have here and found a box of new spares for 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.

> The 5120 KHZ frequency-reference output from my M5, 100Hz Synth, module is only about 40mV P-P even when disconnected from the rest of the radio. Manual says I should have 2,8 VRMS.  I've changed the oscillator and buffer transistors to no avail.  DC voltage seem OK.
