ePMP 1000 connectorized p2p radio link became down every evening in winter season. Any solution?
Hi. We'd need to know lots more info. :) What signals, noise floor, what frequency, what firmware version, etc, etc.
Generally speaking, it could be moisture in a connector perhaps. Depending on the temperature, it could be warming up and forcing the condensatoin out of the connector (and the link works) and when it cools down in the evining, the air in the connector contracts and that draws moisture in (or causes condensation in the connector) and the link can stop working. At even lower temperatures, that moisture can freeze and the link can start working again. So, if you see a link dropping off around freezing temp, but it works fine 5 degrees above or below freezing - it might be a poorly sealed connectors.
BUT - that's just a wild guess of one of the dozens of things that can be doing this. We'd all need to know all the stats - signals, noise, frequency, firmware, distances, firmware, antenna types, etc.
