Hi guys

I've bought a second hand NASA stand alone AIS. With a "stubby" on the pushpit the signal strength bar sits around the bottom 1/4 of the range...can that be right? Its not my BMC connnection as it was a ready fixed one onto the VHF flex.

Also, the unit can be se t to recive channel A or B. Which should it be set to? Going back and forth in the set up is irritating as hell!

Finally, Is it always north up or can it be set to heads up?

Thanks in advance
