[Milsurplus] Boehme tape machine printouts

[Rich MC Clung]

The RD-60 was used to record Burst Transmissions originating from the AN/GRA-71 (thru a suitable transmitter and dummy load with a detector circuit to provide acceptable voltages to operate the undulater circuit of the inked pen recorder in the RD-60) by US Army Special Forces Electronic Maintenance Personnel repairing and testing the AN/GRA-71's, at least until 1983 when that was my last contact with them.

Ralph,

>From the American side: I'm only familiar with the US  'RD-60'  inked tape recorder. If I remember correctly it was called undelator tape... maybe not. In the 60's it wasn't used to record CW, but was used as an analysis tool by the non-morse guys. It would have been burned after use each day. I don't believe it was sent back to a higher headquarters. I don't think it could follow high speed (burst) code. (The RD-60 was famous for throwing ink all over.)

But I was a maintenance man, not an op, so I'm not absolutely sure of all  their procedures. I was one of the items I first worked on in 1960.

I don't remember when they were withdrawn from use, but it was probably before the mid 70's... but maybe that was just where I got stationed

The NSA museum at Ft Meade Maryland might have some examples, but I cant think anyone else would have kept them.
