duPlex button
Duplex operation allows the TX6100 to
transmit on a different frequency to that
which it receives. This allows operation
through repeater stations in your area.
Repeaters automatically re-transmit your
signal over a much wider area, providing
greatly increased range. The Duplex mode
only works on channels 1 – 8 and 41 –
48. With Duplex selected, your TX6100
actually transmits 30 channels higher than
it receives.
To activate the Duplex mode
Select a duplex channel (1 – 8 or 41
– 48). Briefly press the
DUP
button to
toggle duplex on or off on that channel.
When Duplex mode is enabled on the
selected channel,
‘
DUP’ appears on the
display.
Duplex can be enabled or disabled
separately on individual channels.
