Re: QCX+ SSB mod - display blank

Hi Mike,

Great build!

It looks like the fuse settings are incorrect, resulting in setting XCK clock output on enable pin 6.
If you program with Arduino IDE, simply run a "Burn bootloader", or program it manually: avrdude -c avrisp -b 19200 -P /dev/ttyACM0 (or: /dev/ttyUSB0) -p m328p -e -U efuse:w:0xFD:m -U hfuse:w:0xD6:m -U lfuse:w:0xFF:m -U flash:w:R1.02j.hex

Hope this helps. Would you like to document your QCX+ modification when you get it working?  Thanks.
