[Elecraft] K3 - amp plate current wiggles on fsk

[Dave Hachadorian]

I made a few contacts in the cqww rtty today with a K3. 
Everything seemed to work fb, but I noticed the amplifier 
plate current wiggling with FSK modulation. I never noticed 
this with my old TS-850. I hooked up a hand key to the K3 
FSK jack, and when the key went down, there was a short 
power excursion upwards. When the key went up, there was a 
short power excursion downwards. The final power was the 
same after these excursions settled out (about 0.5 second). 
The power excursions were about 100 watts out of 1500.

Operationally this is no big deal, but I wonder if there are 
transients being generated. Has anyone else noticed this?
