Hi, maybe the radio is not capable of this split but I was under the impression it was.

Radio info:
XTS5000 800 mhz (i think all are 700/800)

H18UCH9PW7AN
540008-001487-7
firmware R20.00.01
tuning R01.08.00
dsp R19.50.00
psdt R04.00.00

Trying to add 769.05625 and a few others to the unit but when attempting to save the invalid bong plays and highlights the frequency as invalid.
Can anyone give me some ideas as to why this is happening?

Thank you for reading and I appreciate any help available!
