[ARC5] Hmmm...OT....AN/GRC-109 vs RS-6

[Kenneth G. Gordon]

Well, it looks as though I made yet another "ass-u-me" error. From my 
reading various articles from various places, I thought it was clear (at least to 
me) that the AN/GRC-109 was simply a military-nomenclatured version of 
the CIA's RS-6.

But it isn't: it is a militarized version of the RS-1.

I own an AN/GRC-109, but have never seen an RS-6 except in photographs.

The RS-6 is the much later minaturized version of the earlier RS-1 and I got 
them confused in my 73-year-old pea-brain.

>From what Mike Feher recently told me, there appear to be considerable 
differences in the circuitry. For one thing, the RS-6 has, apparently, at least 
one relay in it, and, again, from what Mike mentioned, I now "assume" that is 
an antenna-changeover relay.

Having such would, it appears, preclude the -30 dB "suck-out" which occurs 
in the '109.

Anyway, I humbly apologize to Mike for my erroneous assumptions, and for 
horning in on something I knew nothing about.

I should keep my 73 year-old mouth shut.
