[Elecraft] Audio Levels for WSJT on K2, etc.?

[Steve Kavanagh]

I'm starting to play a bit with JT65 on HF (using WSJT-X) with my K2 and homebrew interface hardware.  The frequency response of the K2 seems reasonably flat, but occasionally I see power dropouts when the tones change.  This is despite always hitting the requested power at any audio frequency using the "tune" button in WSJT-X. It seems to happen less when I have plenty of audio drive - does it make sense that the K2 power control might get a bit confused by switching transients when there is only just enough audio to get the RF output up to the value set with the power knob? For those who are using WSJT modes on the K2 successfully, what ALC readings do you usually run at ? I'm hoping eventually to get the K2 going with transverters for VHF meteor scatter on FSK441 - is the stock OP1 filter wide/flat enough to work well for this mode?  S/N 4509 is the older of my two K2s. Any other hints for using the K2 on WSJT modes? 73,Steve VE3SMA
