QCX Transceivers
QCX/QCX+/QCX-mini 5W CW Transceiver kit
OPERATING INSTRUCTIONS
Firmware version 1.07
This is the Operating Instructions manual for the QCX, QCX+ and QCX-mini CW transceivers.
All versions of the firmware are compatible with all PCB revisions and all models of the QCX
family. However there are features which are specific to certain models.
1) CAT control can only be used on the QCX+, QCX-mini, and the more recent PCB revisions of
the QCX (unless you have modified your older QCX to add the three components that facilitate the
CAT port).
2) Control of the LCD module LED backlight is only applicable to the QCX-mini and these settings
have no effect in the QCX and QCX+ models.
