Before you get too excited its a bit buggered.....
Was working fine, but now has loud buzzing from speaker....suspect shot /poss water ingress.... The data leads have been cut VERY short but could just about be used /connected. Powers up /mic etc all good.
Was heading for the bin today but thought it may be of some us to someone on here.....bin waiting if not (has MMSI entered too, but may be useful for spares?)
Cover postage and its yours... replaced with another Standard Horizon.....which I have checked and seems to be square.....but may benefit from a paint job....orange perhaps?
