Transmit offset (shift)
All Amateur voice repeaters operate on separate transmit
and receive frequencies. Transmit offset refers to the
amount that a transmit frequency is different from a
receive frequency. See "Transmit offset direction".
Transmit offset (shift) direction
Refers to the direction, either plus ( + ) or minus ( - ) ,
that a transmit frequency is with respect to a receive
frequency. Both the direction and amount of offset must
be selected correctly to access a repeater.
See "Transmit offset".
Tuning Encoder Lock
See "Encoder Lock".
VFO (variable frequency oscillator) mode
The mode that allows any individual frequency to be
selected within the range of the VFO only restricted by
frequency step limitations. When in VFO mode,
frequencies are selected using the ENC/SQL control.
VFO Scan
A function that monitors sequentially all frequencies that
can be selected using the ENC/SQL control while in VFO
mode. See "Scan".
