This menu allows you to enable / disable the IFB Voting function.
The purpose of voting is to allow transmitter to choose and switch to the stronger signal from two
different ZaxNet transmitters. One purpose of this is if you are on a large set you can place a second IFB
transmitter at a different location and the TRX will choose the stronger signal. Just set the second IFB
transmitting frequency to exactly 2MHz higher than the first unit.
NOTE: This Page only will appear if you have the IFB RX TO TX mode set to NORMAL RX and RX MODE
is not set to OFF. Meaning that if the TRX-900AA will ever be in a transmit mode IFB voting no longer
applies and will not be available.
