Well, it looks like I've got some water ingress into my antenna or cable somewhere. I was wondering why I had some funny stats days and now when I think about it it was days it had rained......

This afternoon after a fine day we had a rain storm come through.... my main system which feeds here and FR fell over, whilst my portable system soldiered on.... sigh......

The lightest blue trace is the telling one

Looks like I have some investigating to do next weekend :cry:

Had a chance this afternoon to bring the antenna (a Jetvision A3 https://shop.jetvision.de/epages/64807909.sf/en_GB/?ObjectPath=/Shops/64807909/Products/67020) down ... not good news.

Found water dripping out of the N connector when I disassembled everything. I think its getting in where the plastic joins the metal base. I'll let it dry out inside for a few days and then try to reseal it.

Have pressed the Maxrad unity gain antenna that I normally use with my portable setup into service for the interim.

Following several days of heavy rain, my performance plummeted. My antenna is pretty inaccessible so I could not get to it to examine. Then we had a very cold spell, well below freezing, and my range improved, the best ever! With a thaw, I again lost range, but as things dried out, performance returned. Hope to change out antenna next week!
