[Milsurplus] AN/URT-18 transmitter??

[John Vendely]

Is anyone familiar with the AN/GRR-13 receiver, another fixed-station ARC-58/KWT-6 family derivative, though somewhat different from the 310F-6 discussed below.  Back in 1980, I acquired a bunch of GRR-13 stuff, probably enough for at least one receiver with spares left over.  I'd love to restore it, but have rarely even seen mention of it, let alone schematics for it.  It's been on the back burner all these years for lack of documentation.  Does anyone have a line on manuals for it?

73,

John K9WT
