5.4 Channel selection
There are two modes of operation: Frequency (VFO) mode, and Channel or Memory (MR) mode.
For everyday use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO) mode. However,
Frequency (VFO) mode is very handy for experimentation out in the field. Frequency (VFO) mode is also used for
programming channels into memory.
In Channel (MR) mode you can navigate up and down the channel by using the
▲
and
▼
keys.
Ultimately which mode you end up using will depend entirely on your use case.
5.5 Frequency (VFO) mode
In Frequency (VFO) mode you can navigate up and down the band by using the
▲
and
▼
keys. Each press will increment or
decrement your frequency according to the frequency step you've set your transceiver to.
You can also input frequencies directly on your numeric keypad with kilohertz accuracy.
The following example assumes the use of a 12.5 kHz frequency step.
