ymmThank you for detailed reply.
The ShipXplorer do not provide a forum, and that is why I had to post it here.
I have one, and the specs I have are also very brief: “Dual channel reception on 161.975 MHz and 162.025 MHz.”
Not sure if it is a real dual channel receiver that receives both channels concurrently or a single channel receiver that hops between the two AIS channels?
As regards to your above comment, to receive the 2 channels concurrently, I feel that to do this, the dongle should have dual-tuner. Most likely dual channel reception is by hopping, which is performed by the AIS Software. The lack of specs of ShipXplorer AIS dongle makes it impossible to know all these secrets, unless someone familier with Electronics & Chips opens the cover of dongle and examines what is inside.
Thanks for link to Uputronics 162MHz AIS Filtered Preamp. This seems to be the best available solution to use with a
US $12 Generic DVB-T, no need to spend US $29 on ShipXplorer's AIS Dongle, for which I am not sure what it has in it. Someone has told me that it is simply a DVB-T, and does NOT have a Filter or Preamp or dual tuner, but I dont know how authentic this info is.
I am successfully receiving AIS channels A & B (most likely by hopping done by software), using a
US $10 Generic DVB-T (Black) dongle, and
software AIS-catcher.
To receive AIS using a DVB-T dongle, I have posted the How-To in these forums:
