The sketch that aids in testing the LPF is here:
I don't recall there being a detailed checklist to work through... the closet we have a list of all the functions of the LPF that you can test with the software:
? Serial.println("N ? - Select NO FILT band");? Serial.println("6 ? - Select 6M band");
? Serial.println("10 ?- Select 10M band");
? Serial.println("12 ?- Select 12M band");
? Serial.println("15 ?- Select 15M band");
? Serial.println("17 ?- Select 17M band");
? Serial.println("20 ?- Select 20M band");
? Serial.println("30 ?- Select 30M band");
? Serial.println("40 ?- Select 40M band");
? Serial.println("60 ?- Select 60M band");
? Serial.println("80 ?- Select 80M band");
? Serial.println("160 - Select 160M band");
? Serial.println("1-4 - Select antenna 1 to 4");
? Serial.println("XV ?- Select TXVR state");
? Serial.println("HF ?- Select none-TXVR state");
? Serial.println("PA ?- Toggle 100W PA state");
? Serial.println("TXB - Toggle TX BPF state");
? Serial.println("RXB - Toggle RX BPF state");
? Serial.println("TX ?- Select TX state");
? Serial.println("RX ?- Select RX state");
? Serial.println("SWR - Read the SWR");
Is that what you were looking for?

I think my LPF is acting up.? I'm using 66.4.? I built it a while ago and tested it with the LPF testing software, worked great.? But I seem to remember a detailed checklist to be used with the SW that I can't seem to find.? Am I mistaken, loosing my mind or just can't find it on github?? I need to get the hook ups right when testing the various modes.? With the nanoVNA hooked up to the filter board, filters are switched correctly but when I go through the control board I can't seem to get a good result.
Thanks
