Thanks for jumping in Tom.  Whether all the power is absorbed in the PA does
not matter to me as long as some of it is.  My point is that my transceiver
which is drawing 20-amps DC at 13.8 VDC is dissipating power somewhere in
the radio.  If I take my Omni Six and attach no transmission line whatsoever
or if I attach an essentially lossless length of unterminated line, where is
the power being dissipated?

Let's assume for the moment that the radio cannot attain full power under
this condition.  Where then is *any* power attained being dissipated?
