[Elecraft] KX3 power drops while transmitting

[Jim Klitzing]

Not sure why the body wasn't posted, so trying this message again:

I use the KX3 as a driver for transverters, and I have the power set at 
around 2.5w in transverter mode; occasionally, the KX3 will suddenly 
drop in output power to a couple tenths of a watt while in USB. Turning 
the radio off then on clears it, but of course this is an undesirable 
'bug'. Anybody else have this happen, or know of a solution? Perhaps it 
is an ALC problem?

Thanks, Jim
