Transmit frequency monitoring
Tune
When the is pressed the transceiver will receive on the transmit frequency of a
split transmit / receive frequency channel and the following will be displayed:-
When the key is released the transceiver reverts to normal operation.
When the is pressed the transceiver will transmit full power carrier on the
channel selected, at the of that channel.
When the tune key is released the display will indicate the forward and reverse power being
delivered to the load (antenna) connected to the transceiver. This giving an indication of the
antenna VSWR. The example below shows a load (antenna) with a poor VSWR,
indicated by a low forward power and the high reverse power:-
