Been doing some Arduino stuff on the workbench. I saw an article that used an Arduino for a CW Decoder. Built it but it didn’t show anything on the LCD. After some checking, realized that the schematic I was using and the software I had loaded onto the Aruduino didn’t match as far as LCD wiring. After some experimenting with various pin-out configurations, I ended up with a working cw decoder.
I also built up a breadboard for future Arduino experiments and prototyping. I have three books that I bought this last year that deals with Arduino projects and Ham Radio. This breadboard will be perfect for doing most of the experiments detailed in each of the three books.
I am also doing a VFO/Sig Gen project with Todd, VE7BPO. All of the project will be detailed in the Michigan QRP Club’s quarterly publication called the T5W. Todd is doing most of the work, and my part will only be the VFO section. It is based on a project done by Wes, W7ZOI in 2009. Called the 8640 –JR (a humorous namesake after the famous HP 8640 signal generator) this signal generator uses only 1 VFO but covers three ranges by applying HC74 series CMOS logic for frequency division.
That is it for now. Stay tuned for solder fume snuffing while the temps are chilly and the ground is white!
