[Elecraft] Very LOW RTTY audio solution and request

[Wes Stewart]

I'll confess I probably am not fully understanding your issue.

Nevertheless, when you use "Pitch" to set the tone to 2125 take a look at "Shift" on the IF/DSP control and see if it reads "*2.21".  This should be the default value.  When it is so, then you can change "Width" to limit the garbage you receive around your desired signal.  I assume you have "Net" and "AFC" turned off in your RTTY program.

Personally, I like the 915 pitch, since I like to listen to signals as well as watching them on the RTTY screen and/or panadapter and the lower tone is much easier on my ears. So I set up MMTTY for 915/170.
