It's not so long ago that we had a certain anchor manufacturer claiming to have all the certificates for his anchor when they didn't exist. Does New Zealand count as the Far East?
I have a Baofeng UV-5R like that and they are very popular in the Ham radio club of which I am a member. The antenna it is supplied with is rubbish but the transceiver is excellent value. It would be illegal to transmit on PMR channels or on Marine VHF band, but of course it is legal in the ham 2m and 70cm bands. Also it is legal to transmit on any available means if in distress at sea so mine has marine channels programmed in for this purpose. Interestingly it can also pick up the transmission on 406MHz when you test your EPRIB. Actually I think these units are potentially dangerous in unlicensed hands as they could disrupt communications and distress messages. Most ham radios can be fairly easily modified to transmit on just about anything, but the need to look at the circuit board and snip some diodes would deter the casual user.Whilst we are at it, why not buy a nice cheap VHF... http://www.amazon.co.uk/Two-Way-Pro...8&qid=1388583273&sr=8-7-spell&keywords=bofeng
£30 or less off eBay.

Because it's illegal to use it here and could harm others and could get you prosecuted and the £250 cost is not a trivial amount to spend on an unknown unsupported device that may not work from a manufacturer against which you have no comeback.
Would a visiting Chinese vessel be allowed to use one?
Just because something originating from the Far East claims to have the relevant approvals and testing certificates doesn't mean it actually has....
You need a ship radio license from Ofcom if it is a UK flagged boat. You just go in to the Ofcom web site and update your license and it is free. Of course you need this to get an MMSI for your transponder anyway. Except MOB transponders, they come with an MMSI already.Do you need a licence for an AIS Transponder??
who will know & does that really matterNo evidence of CE marking or type approval to allow it to be put into use in the EU.
Sorry, is it just me but IMHO AIS apart from that shown by larger commercial vessels, is a right PIA in crowded waters. On a busy Summer Saturday in the Solent AIS becomes completely useless, especially the volume of AIS ghosts from those with GPS sets that simply don't know where they are. My personal opinion is that Class B transponders should be switched off in crowded waters unless its foggy e.g. Just light fog lights on a car.

Well ok apart from thatIt matters because if it is a crock of sheet and starts transmitting random stuff at random frequencies it could cause interference over 2000 square miles of sea. Use whatever dodgy Chinese illegal import receiver or outboard engine you want, but in my opinion, if you are transmitting, spend another £200 and get the right stuff for everyone's sake and not just your wallet.
I will need to what if any selectivity there is on both the RO4800 and Garmin 750. I can mark targets of interest on the Garmin, but the issue is first picking those out from the cheese clutter all over the plotter screen.Why not filter out the irrelevant vessels in your receiver?

Or don't sail in the solentMy point is that proposals to ask (or force) small boats to stop transmitting in busy areas are addressing the wrong end of the problem. What people should be doing is demanding better filtering from the display manufacturers. Keep the data available, but use and display it more intelligently, that's the proper engineering solution.

Really not much of a problem anywhere else.![]()
I just bought a Matsutec HP-33 A combined GPS and AIS transponder. At £270 + import duty duty it seems like it is good value. Not installed it permanently yet but initial findings on my blog. I have been waiting for transponders to fall in price and it looks like it has now happened. They are not inherently harder to make than a receiver, it is only low power transmitter and these days I am sure it is all done in a software defined radio. You will notice the only visible difference to the HP-33 which is just a GPS is the addition of a coax antenna socket. Mostly it is firmware it seems.
I just got an email from Huayang Tech confirming the HP-33A (and HP-33 and HP-33N) has EU CE type approval. They attached the certificate of conformity.
The first whiff of anti-AIS so far, mild enough I am pleased to see. A year or two ago the Luddites would would have been out in force with their rants against the technology and how the Mk I eyeball was superior in every way, whenever I mentioned how useful I found knowing name and CPA of a rapidly closing threat. It was the only time ever that I put someone on 'Ignore' after a personal attack for expressing such a view.I'm actually not that keen on AIS
