[Milsurplus] Ebay TBY

[howard holden]

Yes there was a TBZ, it's a VHF transmitter paired up with an RBZ receiver. We had one at the USS Ling SS-297. FWIW the TBW, (had one of those too at the Ling) has suppressor grid modulated phone. It also uses the suppressor modulator to generate the tone for MCW. The GO-9 does not have phone, and it uses the 800Hz 120VAC to modulate the tone for MCW. That's what GO-9s ran on in the aircraft. I know, I own one and use it constantly mainly on 40M. In mine the PS is configured for 60Hz.

The PBY Catalina used a GO-9 transmitter, the ground version of the GO-9 transmitter was the TBW. The TBX also fits in there somewhere as being a primitive and troublesome radio to operate, at least in military context because I have owned and operated them before and love that radio and then there is the TBY.  Looks all related to me! Wonder if there was a TBZ?

Well those went fast, but ha ha, when the note said TBY the first thing that came to mind was something else:
