A new Menu 24 on the BTECH UV5X3 Triband radio is "SYNC" and is ON or OFF. This is a great addition. You can program a Marine channel 16 and see "CH 16" in one display and "156.80" in the other display. For Amateur repeaters, it's nice to know the repeater callsign in one display and the actual Frequency in the other.
The only downside is dual monitoring.
If ON, and you have FREQ in the A display, and CHAN in the B display, changing either channel, either UP DOWN or by typing in a channel number, you will see the NAME in one VFO and the Frequency in the other display.
On the UV5 models, there is no such capability.
