TX/RX signal strength

We just put in a new 14.5 mile link using RouterOS on 5 gig with CM9s. Last night the station end of this link started disconnecting and connecting at about 1 am. I found it this morning when I got up and found I could reach the station at first. It disconnected a couple more times then the rest of the day it has run ok.
Something that I noticed is on the station end under the wireless status, the TX side of the TX/RX would drop to 0 about every three seconds. As the morning went on, this drop gradually became just occasional and the link has remained up all day. I assume that the TX reading should not reflect a 0 but should be stay around the strength we had on alignment. Is that correct? If so, then I assume I may have a power supply or board issue?

Thanks

You should send a supout file to support@mikrotik.com so that they can check the configuration.
