[R-390] RTTY w/R-390

[Gary Geissinger]

Gentlemen,

That looks just like the AN-GRC26D setup I was issued from Air Force MARS in 1974.  Everything you see in the picture including the cables, manuals, and a busted generator.

It used to be in the Keesler AFB MARS station, but the transmitter developed some nasty symptoms and the entire setup was turned into supply as condemned.  That's how I managed to get it issued to me.  Turns out the T-368 problem was a cracked HV feed-thru which would intermittently arc thru and crowbar the transmitter and the fuse in the wall box as well.  Solved the problem for a buck.

It came with 5 Kleinschmidt teletypes and nearly caused a divorce.  The only outlet in the little rental house we lived in that could support the T-368 was in the kitchen.  Hey, where else could I put the setup?  Seemed logical to me at the time.

I turned it all back into Air Force MARS in August, 1975 when I went back to school.  Unfortunately the base MARS station in Denver broke the unit up and issued a different parts of the GRC-26D to various members.  Too bad they didn't keep it together.

Piece by piece I have been reassembling this configuration.  But not the Kleinschmidts!  I would love to find a good CV-116 though.
