Well, hams did convert command set receivers to receiver/transmitter combos.  I did it myself in the mid-1960s by adding a small crystal-controlled transmitter with a 5763 PA tbe (my favorite) in the dynamotor well, but only using an incomplete and real junker R-26/ARC-5.  Even back then I thought that this stuff deserved preservation.

Now about that Type K.  That was a complete radio set, including transmitters, a modulator, and a large control box for four receivers and two transmitters.  Mike Hanz has an A.R.C. diagram of the system, dated December 1938, at:

No one knows of any surviving transmitters, which is why I chose it as an extreme example for my rant.  Apologies!

Hey, I truely wish there were some under your bench.  Then I'd know that they'd get proper care and preservation.
