Pete, N4ZR There have been some good answers for you. (I saved some to help others.) My answer(s) is to the way I read your question(s).
The 'pitch' is the tone you will hear in your earphones, or speaker, on both receive and transmit (cw sidetone). It is nicely done in the K3. BTW, the 'monitor' knob adjusts the cw sidetone level as I recall. I haven't changed it in a couple years. Assuming you are in CW mode: --First, you have selected the 'pitch' that you like to hear. --You have 'CWT' on. --You tune a CW signal near enough to see a bar appear on the 'CWT' scale. --Press 'spot' and the radio automatically tunes the station in to your selected tone. --The signal will also be centered in the filter, and centered on the indicator. Once you get used to the tone you have selected, you will be able to tune well to that tone without using 'spot', or without looking at the display if you are rushed. However, the CWT indicator is your guide. And finally, you said, "I turn the RIT so that the received signal is lower frequency - say 200 Hz. I transmit. What does the station on the other end hear, assuming he is also using USB-CW? Does my "beat note" go up in his receiver, or down?" As others have said, the RIT does nothing to your transmit. But it does change your receive frequency, so that it changes the tone you hear. Not to be confused with the 'pitch' control. The 'pitch' control only selects the pitch you like to hear when the signal is centered in your filter. From then on, you want to tune the receiver to a tone of that pitch, or let the radio do it automatically for you. As for what the station on the other end hears, that is up to that operator, who will tune to one side of your carrier until he/she hears a tone that is suitable. If you are working a station with a radio that drifts in frequency, you will often need to make a correction to the tone you hear by using your RIT. That is it's function. It was a good question. I think you will enjoy it as you understand the workings.

Hi Pete: The K3 reads the actual transmit carrier frequency. That's the suppressed carrier frequency in SSB and the actual carrier frequency in any mode such as CW in which the carrier is transmitted. Changing the pitch has *nothing* to do with this. It will be the same in any case (the K3 adjusts its internal oscillators as needed to give you the desired audio tone without changing the carrier frequency). To be certain, I turned on my frequency counter and checked the transmit carrier frequency while varying the pitch. No change. RIT means *RECEIVE* Incremental Tuning. It has nothing to do with the transmit frequency. Indeed, that's the whole point: allowing you to adjust the receiver frequency without changing the transmit frequency in any way. 73, Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Pete Smith N4ZR Sent: Tuesday, February 19, 2013 1:36 PM To: Elecraft List Subject: [Elecraft] What does the frequency readout mean? I'm having a hard time getting my head around this. My radio is on 3507.02 USB-CW, with a 500 Hz Pitch setting. I change the Pitch setting to 300 Hz, and the display still reads 3507.02. What is this frequency? The suppressed-carrier frequency plus the CW pitch? Does that mean that when I change the pitch, the radio is actually moving its frequency a little bit? A somewhat related question. Same setup, but listening to a signal on the air. "Beat note" is ~500 Hz. I turn the RIT so that the received signal is lower frequency - say 200 Hz. I transmit. What does the station on the other end hear, assuming he is also using USB-CW? Does my "beat note" go up in his receiver, or down? Sorry to be dim. -- 73, Pete N4ZR ______________________________________________________________ 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
