Hello, what are the correct settings for FM Repeater Deviation and High filter in USA?
I want to work some local repeaters but not sure what the correct settings are.

Hello John, the NFM function isn't really correct it needs as far as I can tell to be fixed! also note at this time you Also CANNOT add a + repeater Offset period.

Personally, unless your using SSB or a digital mode for 2M the functionally for FM is broken, NFM actually act more like WFM and for repeaters that's is horrible and even basic FM mode the others will also receive a distorted and badly deviated audio from the EESDR rigs, hopefully this gets resolved

Yes I noticed the distortion as well. I hope this gets fixed soon as I would like to use my MB1 to work some local repeaters.
One thing that helps reduce distortion is to enable Mic AGC in the mic selection drop down, The only issue is that the audio level becomes very low?
