YepFollowing with interest of course.
innovation is a good thing.
Two people have created mods for these radios.
One doesn't sell it and the other does.
What gives me some pause is when you say you had problems with a diode array.
This diode array should be a non-issue if you are using a microcontroller since you can account for it in software.
Unless I misunderstand and this is just a switch mod made easy?
