PTP 600 alignment failure

We are making a Trial with PTP canopy 600.
During the aligning the tone stays stable for some time but in one or two minuts it starts the aligning process again. Client never got a stabel link. This is an over sea link, LOS, with a length of 27 Km. The througtput seen in the Gui is 14 Mbps.
To me it seems that client is not making a good alignment. Is the any other possible issue regarding the alignment procedure.

Thanks in advance.

did you diable the aligment when you finished? ( don’t mean that rude, i made that mistack once and almost didn’t catch it) also if your are useing the conectrized verson, make sure your poles are correct on both ends, they don’t like being reversed :wink:
