I managed to make a short 2 minute recording of the audio output from my CRX1. I don’t know enough Morse code to copy what was going on, and it’s going too fast for me to copy anyway. Hopefully it gives you an idea of what the CRX1 sounds like.
I’m really enjoying the simplicity of this little receiver. Attach the antenna, connect a power source and you have two knobs to turn that tune and adjust volume.
Assembling CRX1 was a lot of fun, and really didn’t take as long as I thought it would. Working on it a couple hours a day, it took me 4 days to finish. Don’t let the use of surface mount components scare you away from trying the kit out. As I’ve found out, working with SMD is actually pretty easy once you’ve got a few essential items.
