The transmitter was capable of CW, MCW and AM putting out something like 35 Watts carrier depending on which band it was used.
Indeed a early 30's design but with a correct power suppy stable enough for the purpose it was used in, short messages from aircraft to ground.

Hans - yes indeed, sorry for posting about the line-up relying on my memory, which is now getting a bit rusty - I was putting one of these brutes on the air over ten years ago. For some reason I was thinking of the Command sets which have a separate modulator.
As you rightly say - it was good enough for air to ground comms.
