Some additional information:
?
On the QMX on 30m where I measure the drift down in power from 5.2W to 4.8W, the initial current draw is 1.16 Amps.? On 20m, where I don't observe this level of drift, and the power is about 3W, the initial current draw is 0.74 Amps.??
?
On the SW-3B rig measured as a reference, when the output is 5.2W (22.4V on the DVM), the current draw is 0.76 Amps.? It is a more efficient PA.??
?
So the drift seems to follow high current draw of > 1 Amp.? Just looking to see if this is a typical behavior.
