[Elecraft] Experience with KXPA100

[K8JHR]

Er...  um...  is such a large voltage drop typical?   We don't see that 
happening on Brand X amps using good power supplies.  I understand the 
voltage drop when going from, say, 10 to 100 watts should be minimal, 
like no more than .2 volts.   I have also seen this sort of power output 
weakness in some transceivers which are rather picky about voltage sag 
when running full tilt.

I would check the power supply and try one that does not sag more than 
.1 or .2 volts on full power.  I suspect the amp is good, the power 
supply not.

Just My take.

The voltage drop at this power is about 1.2 V according
to KX3 meter.

The voltage  meter of KX3 shows then 11.1 V at that power.
