Question about Futaba 9c 50 mhz output.
It may not be required with the 50Mhz module? Dunno. BTW, just to give you an idea. 700MW's transmitters (should) drain about 145ma of juice. Just to compare 1 watt is only 208ma. Xmitter power does not significantly effect battery drain. Unless it's tuned wrong, then you'll lose power in harmonics and heat.
