[ARC5] TBW pics in field use

[kd3ht at epix.net]

I believe at one of w1nzr radio events, ka1gon brought his tbw/rbm system and set it up.  not a military use, but followed the manual. 
I'll see if any photographs exist I can get a scan of.

Beautiful setup!  According to the book 90 South by Admiral Richard Byrd, a TBW was flown into South Pole Station to serve as its first main HF transmitter during the building of the base in the 1950s.  I don’t know if there are any photos of it.  It’s not stated what the first HF  transmitter used there was, but apparently it was a much lower power unit, based on the discussion about the TBW set’s arrival.  Perhaps an RT-77/GRC-9?
Maybe Mike, WU2D knows!  He did an excellent article for the AWA and Electric Radio on the subject of radios used by the Byrd Antarctic expeditions.
Charlie, KA1GON has a complete TBW/RBM field system, IIRC including the gas powered 800 Hz genset.

G'day all I've never seen a pic of the TBW/RBM sets deployed in the the field other than the staged pic in the manual. I've seen some pics of the set up inside a building..but never in operation out in the Pacific war. Has any one..maybe I've missed something??Tnx PaulN6FEG
