Last night was a 40Hz wide signal centred on 137770.0.  Two different
fonts appeared throughout the evening, the simple 8x5 one initially then
the 10x8 font.   Power was up as the antena has dried out and I tried
pushing the amp to nearly 700 Watts - no trouble with a low duty cycle
signal like this but about the limit for IRF840 devices, the heatsink
starts to get warm at 100% duty cycle.
