Hi Dick,

No ideas except to accept it. Have you looked inside?? There is
a *reason* it is so small!!! And heavy. It is not really a very
friendly QRP rig-
Receive drain = 1.38 amps (backlight on medium)
Transmit (lowest power) = 4.87 amps
38 volts pk-pk into my dummy load = 3.61 watts
Efficiency at QRP = 3.6/(12*4.9) = 6 % !!!

But I love mine, too. I wish they had allowed for some way to switch
out the
final PA amp, but I wouldn't mess around inside it, although
theoretically all you
need is a 3pdt switch. Switch the PA in / out, and switch off the power
to the PA bias circuit (about 3 amps worth!).

BTW, has anyone been able to wrest a copy of the schematic out of ICOM's
clutches???
