Agreed Ray! And yes the GO/TBW might be based on the TDE, although the TBW and GO are maybe by comparison lightweights. The TDE and TCK also require a MG set. The 803 is indestructible! They should have never come out with the 813 although it's rated for higher Mhz.

Subject: Ebay TBY now TBW

I built up and ran a TBW for some time, sold it off a long time ago. Fun transmitter. The 803 output tube was almost indestructible! Did a video of it back in the old SD analog days at :

The GO and the TBW always appeared to me to be a light weight version of the shipboard TDE transmitter. Don’t know if that’s the case or not. For a long time wanted a TDE or TCK for playing around with AM but now days all I can think of is how much that stuff weighs.

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?
