Ya, no VNA here. So I'm stuck with the SWR/Power meter to do my investigating. The other problem is the Holyoke repeater is also having issues currently. So it's hard to tell if it's me, or them, or both at times. I have two other repeaters, one nearby (7 miles) and the other farther (17 miles) while the Holyoke is 21 miles. The other two are always good for contact.
I can hit the Holyoke repeater with my HT and during those periods of me not being able to hit the repeater with my base unit, I can also not hit it with the HT. So I've always assumed it's atmospheric. For the entire summer it was full quieting. Winter came along and now it's a crapshoot. The whole thing is just frustrating.
