I heard Eje telling folks at ISPCON that the chip that selects the
antenna port for diversity on that module (I believe) was VERY sensitive
to static discharge. Someone mentioned seeing about 20 db of attenuation
when it fries. It sounds like you may have seen this first hand? Eje, if
you are here can you confirm that this is the same module you said was
quite susceptible to this damage? How did you say you have protected
against this damage? I am sure it is surge / lightning protection but I
think you mentioned a particular product that had given you good
protection from this failure issue with these modules and was very cost
effective. I assume Eje is on here?

Have you tried replacing the SR2,
we had just replaced two, we were getting -80s on a small backhaul, MT to
MT, and after we swapped the radio, we were back at -60 .. Why, got me!

When I use sr2 my ack timing is all over the place, like 300 and the
links are crap. I drop in a cm9 and all the ack's fall to 30's where
they should be. This is all on MT.

The cm9 is rated for 17db
The sr2 is rated for about 26db....
we are happy with the sr2, sr5 and sr9. all deployed and work well....

I replaced a star os/sr2 with a mikrotik/cm9 setup on an omni. I
thought it would help my noise issues to get rid of the amped up
sr2. It may have helped a little but now I have signal that I think
it quite a bit less at the clients. What level of power is the cm9
at by default in a mikrotik and if I switch it to manual what could I
push it to?
