I initially sent this to just Pete, but found other posts: The intent is that the ATU IN LED be illuminated when the ATU is switched in with the ATU MODE button, and the ATU BYP LED is illuminated when the ATU MODE is BYPASS and also when the current ATU setting, with ATU IN, is “bypassed”. Each ATU full search tune checks the bypassed setting first, and if the SWR with the ATU bypassed is good enough, then “bypassed” is stored as the preferred ATU setting for that frequency. “Good enough” defaults to 1.2 to 1, but you can change that with an SWR bypass threshold menu item. For example, my 20 meter beam is resonant low in the band. Down there both ATU LEDs are lit. Up the band only the IN LED is lit. I don’t have to remember to turn the ATU off at the low end, it remembers the bypassed setting. Early firmware lit one LED or the other, indicating ATU MODE. Field tester feedback suggested lighting both LEDs when the ATU function was switched in and the current ATU setting is bypassed. 73 de Dick, K6KR
