PTT is a jack on the K3 rear panel that performs as you describe MOX below when it is shorted to ground. Typically a footswitch is connected to the PTT jack. QSK and SEMI break-in are disabled in this mode. However, the opposite is not true. That is, PTT is still enabled when QSK and SEMI break-in are active. However, in this case, QSK or SEMI break-in will over-ride PTT and put the K3 into transmit whether or not PTT is closed. And, if PTT is released (open), transmission can still continue, or commence, whenever there is a key closure. > Pressing MOX is the same as pressing the PTT and holding it > there until switched off.

It is on every radio, perhaps named differently, that I'm aware of except the K2. All that's happening here is making sure this standard capability is included in the K3. It seems like big deal because of all the discussion and length of the reflector threads. 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
