Re: [Elecraft] Choice of CW pitch
OK, that explains why what I've been doing has been working! I set the sidetone pitch I want and leave it alone. Everything else seems to work out fine. I do have my RXEQ set to reduce higher and lower frequencies but the RXEQ is pretty broad and probably isn't contributing much regardless of my PITCH setting. I thought for awhile that that also improved the operation of the CWT indicator but finally decided I was just making up fake news in my head.

Re: [Elecraft] Choice of CW pitch
Is the center frequency of the K3 Audio Peaking Filter adjustable? I didn't think so but honestly don't really know. The coast marine station I worked at in 56/57 supplied 1 Khz [well 1 Kc in those days] sidetone to each position. It was higher than most liked, we had receivers to listen to our TX channel and most used them. Something more comforting about hearing your own signal rather than a disembodied concoction from the RX site. The older I get, the lower my sidetone goes.

Re: [Elecraft] Choice of CW pitch
I get the best response for CW pitch volume from the K3 stock speaker with my 60 degree deflector horn on top. The length was determined by experiment and gives a very noticeable boost at my desired pitch of 500Hz.

Re: [Elecraft] Choice of CW pitch
When you've got a weak signal peaked in a narrow filter or APF, that's the time you'd like to optimize the pitch. Adjusting the VFO/RIT for a different pitch is not really an option at that point. You're right though, PITCH as implemented is mainly meant to pick your favorite tone and pretty much stick with it; not for trimming up individual signals like you would with AF/RF gain. 73, Drew AF2Z On 09/22/18 07:11, Nr4c wrote: Come on!!!
