Like with the Backpackers series, you do get to know who is and who isn’t SOTA compliant (as opposed to “complaint” hi). As far as last night goes, I think it was just myself and Robert GM4GUF/P that were good for SOTA. I can’t be 100% sure about Robert either, as although we tried to have a QSO, the QSB rendered it impossible at the time. He has been SOTA compliant on UKAC nights in the past though.
So definitely no S2S contacts for me. You do get to know who the contesters are that are also SOTA chasers (Keith G8HXE, Ron GW4EVX, Roger M0OMB, Neil M0WBG etc) so I tend to chuck in the SOTA ref with the other details if it’s one of those guys. Other than that, if I am running, then I’ll mention SOTA about every 3rd or 4th call.
Generally speaking, other /P stations on UKAC nights are not SOTA, and it’s usually safe to assume that. You never know though.
The headlamp was only needed for the last half hour last night!
