K3 PTT -- done!
Locked

******************************************************************** Joe and all, I have the same questions. Since no one has explained the difference between 'Transmit mode' and "the K3 is now transmitting since QSK has been started with a keypress" - I would believe that the PTT input is redundant when in QSK or Semi-break-in modes. Yes, a little clarification (or language lessons) seem to be appropriate here. How is 'Transmit mode' different from 'transmitting already because the key was tapped'? Does closing PTT when in QSK mode inhibit a return to receive until the PTT is released? - that is the only thing I can think of. It certainly seems that the generation of RF is controlled by the paddles in any case (except for the new TX inhibit condition). A few things were clarified, but confusion still reigns high in my mind. 73, Don W3FPR ******************************************************************** Am I missing something or is this PTT stuff simply the same as MOX (in a Yaesu)? Pressing MOX is the same as pressing the PTT and holding it there until switched off. TX light is on, RX is muted (ie "Transmit Mode") and hitting the key will transmit RF - it overrides both QSK and VOX. MOX will only actually put out RF of it's own accord in AM or FM modes that involve a carrier. In QSK, both MOX and VOX are disengaged and "Break-In" is switched in. Now hitting the key simultaneously kicks in the PTT and transmits RF but only for the duration of the key press. I thought this is pretty standard stuff and would assume the K3 would more or less follow this protocol. But as I say maybe I've missed something subtle in the discussion in which case I'll apologise and go back to sleep. 73, Stewart Rolfe, GW0ETF _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Thanks for good explanatiion of PTT in K3.
I would also hope that the K3 carrys forward the 8R feature built into the K2. This keys some amps perfectly well. de Joe, aa4nn _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

> as MOX (in a Yaesu)? 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: [hidden email] You must be a subscriber to post to the list.
