[Elecraft] Re: QSK K2

[Wayne Burdick]

If you want to simulate the effect of PTT activation in CW mode (e.g.,
for use with a footswitch), you'll need to ground the MUTE line on the
control board. This must be done with a switch or an open-drain or
open-collector driver. Be sure to bypass the line for RF, and use
shielded cable, since otherwise noise might be picked up by the audio
amp/muting circuitry.

When you ground the MUTE line the receiver mutes, but the rig still
won't go into transmit mode until you key it with the key or paddle.
