through 38 and 71 to 78.
e.g
CH01 on Duplex mode will receive on CH01 but transmit on CH31.
CH02 on duplex mode will receive on CH02 but transmit on CH32.
If you transmit on CH01 duplex mode, you are actually transmitting on
CH31.
The repeater station down converts your signal and retransmits on CH01.
Your ULTRA550 allows you to pre-select Duplex operation individually
on each channel.
