Thank you Alan. The drivers are installed properly now. And thank you Ludwig. I can see the audio drivers, too, after following Alan's instructions. However I, still, cannot change the mode nor the

Maybe some steam punk-ish levers?? Momentary contact, of course.? Maybe a gauges of some sort to measure voltage & current?? GREAT looking build.

Larry, I'm fairly certain that you delete them from the band list seen in terminal mode. Manual should help. 73 Alan G4ZFQ

Thank you Ron… that’s precisely why I asked the question because the newer version uses disc capacitors, and I was not certain if it would make a difference. i’ll give it a go and report

The replacements CAN be polarized but don't have to be. The newer versions use 1 uF ceramic caps. Either is OK Ron [email protected]> wrote:

I think they are all this way. I own 3 of them and they all look the same but work. Adding a wave step would add more cost per board. V 2.0 is shipped with firmware loaded so the port is
