    Default Ultra Narrow IF

    Does anyone have any insight into the option for 5.76k or 7.8k settings beyond what is in the help menu?

    Hi. I just recently changed this setting myself.
    You use the 5.76k IF setting for 12.5KHz or narrower channels, and use the 7.8K IF setting for 25kHz channels.
    Since I use my XTS3000 on the ham bands, mine is set to 7.8k.
    The 5.76k setting basically helps to prevent adjacent channel interference.
    Cheers, Chris.

    Read the help. 5.76K is intended for dense urban areas with significant adjacent channel interference. It tightens up the receiver a bit, at the expense of sensitivity. If you don't have this issue, regardless of wideband or narrowband, run 7.8.
