Hi Tom, et. all,
Nice project, Bob...
I am rebuilding my homebrew amplifier (I use it with my K2) and would very much like to incorporate auto filter selection.??
I have 7 filters rather than 5, so would need to add 2 more output? lines.?
Also, an additional output would be great to enable the amplifier a few 10s of msec after filter relay output is stable -? to avoid hot switching.
Is there any more detailed information about the circuit / schematic?? ...Pinouts, etc.
It has been many decades since my last C programming and I am really rusty (so rusty the brain is seized) also I am Arduino ignorant.?? But, from looking at the code, it appears these might be do-able, just not sure.
Would like to get more info...? My email is good at qrz.com...
Thanks,
Woody?? KZ4AK
