Can an MTX850 go out of band?

[motor59]

I have HVN9067 software, and can read the radio OK.
It says the TX range is 806-865, RX range 851-865.

For what I need it to do, I'd like the TX range to be 806-869 and the RX range to be 851-869.

Any easy way to tweak those 4mhz out of these units?

Thanks in advance

(MTX850 and 8250 are in the same family)

See that - I guess you just need to know what to search for.
Thanks!
