KEY OUT in CW mode is the logical or of straight key, internal keyer and PTT. Turning on VOX neither asserts nor gates KEY OUT To prove that, place in CW mode, and hit the key or the paddle with VOX off and PTT not asserted. If your amp is connected, out of standby, and uses KEY OUT, it will change state with the CW. This *IS* a FIRMWARE directed behavior. It is not implicit in physical circuitry anywhere. The requested behavior change does not require a hardware change, even though the KEY OUT jack is a hard conversion of 7R from zero state to high voltage short at KEY OUT. When in CW mode, with neither VOX nor PTT asserted, leave the K3 in receive mode, use straight or internal keyer assertion to place monitor audio on the three RX audio DAC's only. This is entirely a firmware change, though possibly an ugly one. 73, Guy. ______________________________________________________________ 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
