[Elecraft] K3 FSK power transients

[Joe Subich, W4TV]

Are you using DATA A or trying to force FSK-442 through the K3 in
USB with the TX_EQ enabled?  Again, I see *NO* frequency effects
(crest factor < 0.1 dB at 30, 60 and 100 W) with my K3 when using
DATA A and the LINE In.

Also make sure your sound card does not have any "enhancements"
enabled.

73,
