QUESTION ABOUT: Use a frequency offset to place FSK tones slightly above the defined frequency for SSB reception

[geokscott]

I'm programming an RS41 for CATS. I see the instruction in the config.h file say: Use a frequency offset to place FSK tones slightly above the defined frequency for SSB reception.

I'm using and offset of 430502000 for the 430.5 standard CATS freq. When I look at it on a waterfall, it looks like I could go even a little more. Is there a standard offset for this that I should know about? Or do I just have to fiddle with it until it's broadcasting most of the signal just above my frequency?

Thanks for any help or guidance!
