[Elecraft] K2 turning power behavior

[Michael Harris]

G'day,

At the salt mine so not near #1400 at present.

How exactly do you determine that transmission has stopped?  Does the
receive unmute?

On #1400 when I cross the QRP/QRO boundary level, in either direction,
there isn't any unmuting and just for interest I set up as split and
the TX frequency remained selected.

I must confess that the one thing I didn't check for was modulation.
I get the impression that the "feature" is subtle rather than gross.
Will check again at the first opportunity.

Regards,

Mike VP8NO
