"Are you saying that with VOX off, and no external source of PTT, your K3 is going into transmit when you operate your key? i.e. you see the red TX LED light? "
Yes to the first, no to the second. To explain - in CW mode the K3 sends a PTT signal on the keying line whenever the key is down. It does not matter if it is a straight key or the memory, the PTT output is still active in sync with the sidetone. The radio does not transmit but that's hardly an issue in my case as its only putting out 1mW at ~28MHz. The problem is the PTT signal when moving rapidly causes a lot of relay chattering and bias supply switching, I have not tried it with my 24GHz which uses a rotating waveguide switch, but I am sure it wouldn't be good for it. In VOX mode with QSK I could understand this hapening, but when VOX is off, you wouldn't expect the key to activate the PTT signal. A way around that is to have a VOX hang, but that appears only to work on SSB. -- View this message in context: http://elecraft.365791.n2.nabble.com/Feature-request-Disable-Break-In-on-K3-tp7578303p7578315.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
