[Elecraft] K1 Instantaneous frequency shift at top of transmission

[a.yoshida]

Hi all

My K1 (#1963) is now ready to go but have a problem.

At the top of transmission I find a little frequency shift

which we sometimes found in old days.

I do not know what I say in a word, "chirp" ???

Following are test condition,

*Dummy load connected
*external PS for 100W class tranceiver
*VFO range is 80KHz
*output power 5W (found the same in 2W setting)

Any suggestion will be appreciated.
