The little Chink generator is easy to crank but voltage dropped very low during transmit with RF power output dropping down to less than 75 mW.
I made an emergency capacitor pack using Super Caps. Cranked until the caps reached  9-10 volts. The receiver could now easily run for an hour and I could now make several short FD exchanges  running 1/2 watt while the Super Caps discharged and when they got down to 6 volts I would do several cranks.
The little 3 phase hand crank generator was a lot easier to crank than the "Clansman" that I used  during a previous FD.

Also easier than pedaling my G-76.

Amazing what you can do with low RF power. Supers Capacitors.  PFM
Happy 4th to all - its good to be here and not overseas to celebrate.
