[Elecraft] KPA500 10 meter behavior

[Robert Redmon]

I put my KPA500 on 10 today for the first time and noticed a rather 
unexpected behavior. Often, on the first character of transmission, the 
K3 drive power apparently spikes, driving the KPA500 to more than 700 
watts. This seems to stabilize following that first dit or two, but I 
have to reduce drive to below 12 w before that behavior stops. Seems the 
100 watt module in the K3 is behaving poorly. Anyone else noticed this? 
Doesn't seem to be a problem on other bands. (SWR is 1.3:1).
