rotary encoder at the same time. You will see the cursor move to the left or right 1 digit at a time.
Again, the cursor under the comma indicates 500Hz tuning steps.
To cancel RIT tuning (reset the RIT to zero), press the “Exit” button; this returns to main operating
mode and sets the RIT to zero.
To return to the main operating mode, press the “Select” button. Now the RIT is displayed under
the VFO, for example:
A14,060,00
+0,300
Remember that cancelling RIT mode is easy, just double-click the “Select” button to show the RIT
editing, then press the “Exit” button to cancel it (which means, set it to zero).
Transmitting is possible while the RIT display is active. You can also press the rotary encoder
shaft button to select sending a stored message, while the Speed adjustment setting is active.
3.4 VFO mode
A single press on the “Exit” 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.
3.5 VFO A/B operations
Frequency swap: the contents (frequency) of VFO A and B can be swapped by a single long key-
press to the “Exit” button. This can be useful when setting up the VFO frequencies.
Copy VFO A to B: To copy VFO A to B, press the “Exit” button with a long key-press then a single
short press. It is similar to tapping a CW ‘N’ slowly on the “Exit” button.
Copy VFO B to A: To copy VFO A to B, press the “Exit” button with a long key-press then a quick
double-press. It is similar to tapping a CW ‘D’ on the “Exit” button.
3.6 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 “Exit” button. The
display now shows something like this:
QCX operating manual, firmware 1.07, manual edit 0.03
