Gang, I think everyone should be informed of this effort by JH3BTK. He did modification for JT-65 and FT-8 before and now he is supporting CAT for

Gang, https://youtu.be/8ZXhJMG3lvQ Finally I got the OMRON switch and completed the Pixie 2 build. I hope you will love it. As a bonus, I introduced NE602+LM386 receiver build. Thanks, Adam
