I just witnessed my FT-891 transmit during an "Incoming Connection Request" message. This is very disappointing since I had the Disable PTT box checked. I run an 80 meter end fed with a multi-tap toroid to match various bands. The tap is currently set to perfectly match 40 meters, but I had switched the program over to 20 meters just to check the band for activity. Not sure if the rig has self protection against high SWR. Is this an expected event, or should I be able to trust my rig will NOT transmit when I tell it not to?
As a follow-up question, I have occasionally left the program running just to see how many stations have beaconed or called CQ overnight and in the morning noticed the "Incoming Connection Request/No luck. Maybe next time" message and have wondered: Since I do not send beacons unless I am sitting at the rig, does this mean someone has randomly tried to connect with me even though I have not been active for many hours?
