Hi NorthUp

Thanks for your suggestion, have tried both sites and they just confirm the absence of AIS in our area, nearest AIS signal is Fishguard (Irish Ferry) 30 nm away. Aberporth traffic (12nm) may occasionally transmit AIS but not a regular event.
Will talk to NASA and see if they can suggest something, it would be nice to know it’s working before sailing over to Ireland later this month.
