It's possible that the same display is used for other radios
that use FM. FM is not intended for use on the CB band,
but some folks do use it there. They do not use a regular CB
for this. You can't get FM on your AM/SSB radio because the guts of the
radio
is a very different beast indeed.
Although it might have been a good idea for the FCC to
to make use of FM on 27MHz. It would have prevented
"skip" and that would have made them happy.

I own a TRC-485 AM/SSB xcvr.
I noticed when looking at the display that there is an FM indicator.

How can I receive/xmit in FM mode?
Where is the mod for this?

Thank you.
