[1000mp] Strange bahaviour on 80 meters

[1000mp@mailman.qth.net]

Actually, thinking about it, transmitting into a dummy load will
not really show anything, because the swr will be flat over
the spectrum, and the issue here is whether or not out of band
energy is getting past the output filter. If it is the latter,
it will not show up into a dummy load, but only when using resonant
antennas.

Thanks again for the input.

cheers, Paul - VA7NT
