If the issue stays at the same site, and does not follow the radio it is an RF path issue… or possibly a power issue causing problems.
Remember you changed frequency bands as well… clear LOS at 11GHz and clear LOS at 18GHz are not the same. My guess would be a Fresnel zone obstruction near the side having issues.

We have a B11 link that is 6 miles clear LOS (we currently have a dragonwave horizon compact plus 18Ghz link in place that the B11 will be replacing). The PCN states we should have a -42.5 the B11 interface states we should have a -40.9. On the near side with is also the AP side we have a -42 (as expected) however on the far side (station side) we have a -53.2. Both sides are using the Jirous 2' dishes. We've tried swapping radios on both sides, i've downgraded to 1.3.1 and back to 1.4.1 and we've moved the dishes 5' vertically on both sides with no change. the station side is always about 10-12db worse. We are not on a sidelobe since the other radio is at expected signal level. Mimosa has stated they are "looking into it" and they have another customer with a similar problem. I've provided them VPN access and they have run some diagnostic scripts. It's been almost 2 weeks since I first contacted mimosa and they don't have any answer other than "we are working on it". I'm ready to switch vendors to another product. We have to get this link live because it's going to start snowing here soon. Anyone else have this issue or have any other ideas of what to try?? -Sean --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
