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.
