VFO mode
A single press on the right button changes the active VFO mode. There are two independent
VFOs named A and B. There are three VFO modes for using these VFOs:
•
VFO A is active as transmit and receive VFO; if non-zero, RIT is applied during receive
•
VFO B is active as transmit and receive VFO; if non-zero, RIT is applied during receive
•
Split: VFO A is used for receive, VFO B is used for transmit; RIT is ignored completely
Split mode is often used by DX stations, they transmit and receive on separate frequencies.

VFO A/B frequency swap
The contents (frequency) of VFO A and B can be swapped by a single long key-press to the right
button. This can be useful when setting up the VFO frequencies.
4.9
Frequency Presets
There are 16 frequency presets which may be used for storing your favourite frequencies, or for
just temporary use, or however you wish!
The presets are labelled 1 to 16, and can be individually edited in the Preset menu (see later).
Often it is more convenient to just save them from the current VFO frequency.
To show the list of preset frequencies in normal operation mode, double click the right button. The
display now shows something like this:
A14,027,50
S 1 14,035,00 L
The top row of the display shows the currently active VFO frequency as usual.
The b
ottom row shows a “1” in the 4
th
character, this is the number of the preset displayed. The
next number (here 14,035,00) is the frequency stored in Preset 1.
Use the rotary encoder to scroll through the list of presets until you find the one you want. Once
you have selected the desired preset, press one of the three buttons to Save, Cancel or Load the
preset, as follows:
•
SAVE the current VFO to the selected preset, by pressing the left button
•
CANCEL the preset operation (back to main operating mode), by pressing the centre button
•
LOAD the selected preset frequency into the current VFO, by pressing the right button
The “S” in the first character and “L” in the 16
th
character at the far right, are intended as a
reminder of which button to press to Save and to Load.
