He wants to vary the pitch without moving the signal in the bandpass, Don. That's a non-issue using a wide bandpass and one of the reasons I don't use narrow filters except on rare occasions when absolutely necessary.
With a wide pass band I can just move the VFO (I'm *always* in SPLIT mode so TX stays on frequency.) Like Drew, I often shift the tone of the signal as I'm copying based on the nature of the noise, but it's not practical to do with a very sharp filter when straining to make out a weak signal. Losing the signal at all while juggling SHIFT means missing characters and hunting for it again with uncertain results. Ron AC7AC -----Original Message----- Drew, ?HUH? The "pitch" function that you say you want - change the pitch of a received signal - already exists, just turn the VFO knob, it will change the pitch of the signals which are being received. Normally one would want to tune the desired signal to the pitch which matches the sidetone, not the other way around. Just tap the SPOT button to zero-beat, in fact the K3 can do that automatically (within a limited range). Things that are changed by the PITCH control are the pitch of the sidetone you listen to during transmission, the frequency offset used for transmission and the CWT center frequency as well as the position of the center of the CW passband - it does not change the pitch of signals being received. Can you be more specific about what you want. 73, Don W3FPR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
