We had a Dragonwave radio that would do something similar a few years
back. In our case, I wasn't sure which end of the link was going wiggy.
As a trouble-shooting technique, I wrapped the suspect ODU in foam
insulation, which actually allowed it to function until we could replace it.

I have an old Exalt ExtendAir RC11000 link from a company we
acquired. Last year, it would stop working if the outside temperate
went below -8 F. Signal level would be fine, but the link would just
stay in the down state, and BER would be sky high. No Reboots or
ethernet bounces on either end, and the link would start working again
as soon as it warmed up. Since it had to be so cold for it to stop
working, that only happened for a few days last year and I figured I
could just live with it. There are only 2 small customers fed off
this site, And I have a low capacity backup link to the site.
The Last 2 nights we had temperatures that dropped below 40 degrees
for the first time, and the link started acting the exact same way.
So it must have broken more over the summer. I'm guessing there's
some sort of heater on the RF chip that's failed. Would that affect
both the RX and TX BER, Or have both ends failed simultaneously? is
there a secret Telnet command to check the heater status?
