Hi Jim
I found a serious bug in my previous Ver.6.xx commits. Perhaps you can announce this on the goggle group as I don't have an account. Somehow between Ver.5 and Ver.6 I inadvertently must have erased one line of code, unfortunately a critical one which asserts the chip select for the I/O expander on the LPF board. Yes. Yikes. Ironically since I really only operate on 160m and it doesn't require any LPF relay activity, and my brief tests on other bands miraculously didn't result in any damage, I never realized this had happened. My only guess is I deleted the line while editing comments. I don't know, as I never had any reason to touch that part of the code. My life sometimes seems to be a playground for Murphy's law. The latest commit has corrected this and improved some minor display issues and the auto-band switching via RF detection. The amp must be in MODE == 0 (OFF) for auto band switching to work. I recommend nobody use any Ver.6 FW below Ver.6.05 due to risk to the FETs running into a wrong filter. The new version is up here:
