 This is a website I like. There are lots of videos with interesting projects such as this one.

Thank you one more time for sharing this one. I wanted to ask you a question. What was the transceiver you were more happy about ? The uu80b or the XBM80-2 ? I only tried the uu80b since is almost like the Pititico and thanks to the uu80b I managed to make it easier to do the frequency offset. In the original Pititico that always gave me headaches (hi). Soon will come the FETer. I really want to try it. I think it was one of my favorite videos to watch when I was working out of see and dreaming to return home and get into amateur radio. 73, YO6DXE.

At 80m the chirp was not an issue, but at 10m it was a real issue! So I created the https://sites.google.com/view/g3xbm4/home/hf-mf-and-lf/homebrew/10m-lesser-chirpy which overcame the chirp. Essentially the 80m radios are the same original design. I think the circuit that gave me most fun was the 10m one, without the chirp!
