[Elecraft] turn off head phone monitoring

[David Ferrington, M0XDF]

Yes, this caught me out (for I don't know how many times before) during JOTA, where I was listening with phones, while others were listening on the speaker - so monitor was on (I tend to have it up high, so when I talk, I don't shout, which I have a tendency to do).

Then I key'd the mic and howl!

Just an option to cut monitor on Tx would be good, because by then, I've usually puuled the phones of my head, to hear what people in the shack are saying.
But cutting just the monitor to speakers would be even better.
