FM deviation on 6 Meters.

When using a local 6 meter I am told that my audio deviation is low. I have the mic gain up pretty high. The display shows NFM 11.0 kHz. This seems wide for NFM. I would think it should be more like 6.0 or 8.0 kHz. I have not seen how to select a narrower bandwidth like you can for SSB. Is there a way that I have missed?

    You want the normal FM mode, which will display a RX bandwidth of 16kHz and a deviation of +-5 kHz. The ham standard of +-5kHz deviation generally occupies a bandwidth of about 13kHz. What the Flex is calling NFM is used in some other countries (and pretty much all US commercial two way) but I don't know of any US ham use of that mode.

    Thank you John, I don’t know why I didn’t try that. Much better into the repeater now.
