[aprssig] Receiver overload issues with Kenwood TH-D72

Ah, yes, incandescent lamps. I wonder if the PAR500MFL lamps I have in my stage lighting gear would make good UHF antennas with their built-in parabolic reflectors. ;-) At least they have the wattage rating.

That's not bad! I used to think you could only work line of sight
with CW when using a light bulb for a dummy load... or run
some digital mode at a low bit rate... a very low bit rate! Of
course the newfangled CF bulbs are useless for dummy loads.
The SWR is too high and in any case, they just go up in smoke!
Another reason to buy up at least a few incandescent bulbs
while they are available!
