"...I'm looking to get some feedback concerning through-line loss of the
Ameritron QSK-5. Loss is not specified by Ameritron as a function of
frequency and after recently measuring loss through my unit, I'm seeing
approximately 1.5 dB on 10m, and 0.8 dB on 40m. For those of you using a
QSK-5, are these typical loss parameters, assuming the PIN diodes are
being
fully biased? The 10m loss is certainly a bit more than I would have
expected...(etc.)"
My rough math indicates that 1500 watts out and 1 dB loss dissipates what,
300 watts in the QSK box?? Can't be? My QSK-1500 runs cold. Also, I don't
see any significant loss on the power meter, but I haven't measured closely.
