FT991A Repeater with custom offset

The FT991A is limited to one pre-programmed 'default' repeater shift per band.

Configuring a channel using the RPT option in the function menu applies the default offset for the band. This is convenient in locales where repeater offsets are standardised use a standard offset. The default offset is applied to the VFO. The default offset is not stored with the channel and so any change is applied to memory channels when they are recalled.

To save a per channel custom shift is the channel is saved with a duplex transmit channel using a two step operation.  Duplex channels are distinctly different from split frequencies set with the Split button.
