I'm most impressed, although we already put longer messages through. And i'm curious about the lower frequencies. 100 transmit hours are over now, and it is raining strongly in the moment BTW. You said a day time carrier can be helpful to calibrate your E field antenna. Even that relatively low signal with 300 mA? If so, i would continue to transmit until tomorrow evening. 73 and TNX for the experiments.
