60km wireless link problems

Hi

I have setup an 60km Wireless link with full line of sight using 34dbi dishes and RB52hn Mikrotik Radio Cards.

Ive got an RX CCQ of 80%
and TX of 70%

As soon as I push Data more than 2mb through the link it drops completely.

TX RX signal of -77 but jumps around between -75 - -80
Im using Mimo

Disabled data rates above 18mbps allready and Im using 5Ghz A - NSTREME

Please help me get to the bottom of my disconnects!

I think you should realign your antennas.

regards
