[GreenKeys] Baud rate change

[Roy Morgan]

INTERESTING!!

Early WW-II Navy aircraft carried the GO-9 LF/HF transmitter that ran on 115v 800 cycle AC, provided by an 800-1 rotary inverter. These inverters are now unobtainable. 

I wonder if there are variable speed inverters as affordable as the one linked below that produce 800 cycle output.
