Hi Jim,

I believe we are both thinking of the Doolittle GWY-2A transmitter but that is not the radio pictured in the first posting.

I drew a blank on the GWY-2A, other than it was high HF, on a single channel around 24 MHz IIRC and used high-frequency AM plate and screen modulation.

Now, the front panel of the GWY-2A does have similarity with the radio shown, the same latches and of course the maker. I did get the idea that the radios were re-issued late in WW2 under an AN/ reference and that they were used as some sort of "smart bomb" or something like the AZON remote control system.

It is a remote control transmitter, operating
on 23-28 MC and intended to control an early "smart bomb." One of the AN numbers quoted turned up a Google hit regarding the use of the equipment in controlling captured V-2 rockets during post-war tests at White Sands in New Mexico. I'm basing that on the following e-mail, sent to me via the one of the QTH.Net boatanchor forums, several years ago:-

From Ships 242A, January 1945:

and operating voltage.
