It's straight forward. Since 2.5 is half of 5Khz you just set your service monitor test tone to 1.5 (half of 3Khz dev) and adjust radio-tune-menu or simple-tune-menu to 3Khz. I assume the same thing would work on an RTCM.

Narrow FM setup

Ok, so is it possible to make a narrow FM setup work and sound reasonable?  With this darn narrow banding stuff.  I have a new NXDN UHF module that I can't get into Wide FM mode (like all my other ones).    So I want to set it up with an RTCM as my replacement mobile repeater (gave it to my brother - yeah I know :)…).

So, can I get some recommendations for setup… I obviously can't generate 3khz, nor do I want it that hot on RX either… I do have a compander that I can enable if that might help…

Just curious of those who decided to try this what they did and how they set it up… this is a full duplex Icom UR-FR6000 module… next to the moto R1225 about the smallest full duplex repeater that I know of :)… and cheap too by repeater standards (for a new commercial repeater that is).

Any *constructive* advice appreciated?

Thanks,

Alan
