I'd like to use my QCX in below-freezing temperatures and, to that end, have been looking for an OLED replacement to the 16x2 LCD screen that comes with the kit. I've found one on aliexpress (link bel

After a lot of thinking and over complicating things, I simply dove into a solution to mounting the LCD to the front panel, using 2.2mm lexan. Shown is the sub-assembly, which will fit on the undersid

Greetings to all. I completed my QCX kit and rather then seeing Select Band in the start up it went directly to an 80 meter freq. I'm trying to set it to 20 meters. I have gone through the alignment m

Hello, I have crashed my OCX for a while. Replace some other parts and I have now to replace the MC. So I bought a "Arduino UNO" Programmer and try to write the files. But, it doesn't work. I can writ
