:-) You seem outrageously good at sane requests.

A bit of thread drift: what is Vesper mode for? I've a vesper AIS and had a look at the mode's settings but didn't get to the bottom of it - I couldn't see anything much in the manual either. The AIS (XB8000) is a great bit of kit BTW, that is one software update away from being brilliant (if there were more management and translation options available on the N2K to 0183 interface it would be perfect).

Has anyone got anywhere with getting the UK Met Office model data? I know they've kept it locked away, but I seem to recall some mention to that changing and it's rumoured to be pretty good.

I've an H2000 and replaced my GPS last winter. 

Do you just want the GPS feed into Expedition or into the H2000? Taking GPS data from an H2000 into Exp is not great as there are precision and update frequency issues. If it's a H2000 Hercules then you can send data back to the instruments from Expedition and could feed GPS data that way, but it wouldn't appear as COG, SOG, Distance and bearing to waypoint etc as it would all be in the custom channels. Frankly it's not a great solution. 

A better solution is a new GPS, such as the dualnav,  with a NMEA0183 feed back into the H2000 and a second feed to the laptop, in addition to any connection (NMEA for Hydra, or RS232 for Hercules) to the H2000 for instrument data into Exp. On a Hercules you can then still push exp distance and bearing (I do it as an alternating pair) back to the instruments for display on deck.

I ended up with a new B&G GPS, but that was N2K only (it made sense as I was putting in some other new N2K kit). I then used an H5000 Fastnet gateway to put the H2000 data on the N2K but, but it's one way only (which is a shame, as it worked perfectly - though it needs a firmware update to put H2000 depth onto N2K correctly). I had to use an N2K to NMEA0183 converter to push the GPS data back to the H2000. 

If you're willing to live with only Exp knowing about the position data, then most cheap GPSs will work.

Duncan,

Thanks, that confirms my guess. The question then becomes if it's worth putting the whole lot up the rig or just have it at deck level. If you're getting up to 20nm, then it sounds as though antenna height might not be that critical - though that rather flies against ZeeZee's experience from housing a phone up the rig - unless he was even further off. Though I guess the relatively poorer antenna gain of a phone's antenna would be a factor too. As you observed at the outset there are lots of variables in here.

I've a MiFi type router in the nav station, with one of it's two external LTE antenna connections connected via very heavy coax (RG-12?) to a masthead antenna. It works quite well: the router/LTE transceiver is well protected and accessible down below, but reception isn't as good as I'd hope - more than 5 nm off reception is patchy. My guess is coax length and losses are the issue. I can't recommend the hardware strongly enough, it's reliable and reasonably sophisticated whilst quite easy to set up. I use a Teltonika RUT550, which has now been superseded by the 9xx series. It also is possible to configure it so that it uses the mobile data as an automatic back up to some other WAN connection, such as marina WiFi. I guess I'll replace it with a 5G device in the next year or two, and then the debate will be over the relative merits of a similar arrangement vs a closely coupled/integrated antenna transceiver at the masthead.

Before I tried to do that I'd be inclined to remove the zeus from the N2K and check that the analogues start working again. If you've got an Actisense NGT-1 (or equivalent) on the N2K it should be possible future out what it is the zeus is doing that breaks them - it might well be possible to suppress that (pure speculation on my part!)

For the H3K analogues question:  Tinley are great, but last time I asked they didn't plan to build a n2k to fastnet gateway. B&G's H5000 Fastnet interface only works the other way delivering fastnet data onto the N2K bus (irritatingly the only bidirectional feature is the backlighting). Sailmon or the Tinley A&T processor are the only devices I know that will bridge fastnet and N2k busses. That said, I seem to recall that the H3K analogues were N2K/Simnet devices not fastnet. That would explain why they did work, and suggest that the H5k update stopped the right PGNs getting on the bus. If they are N2K might you be able to put out the right PGNs from Expedition?

For the 2020 question: If you can get get hold of one (Ebay has worked for me) what you really want is a H2K performance processor. That will take some NMEA 0183 in and push it out on Fastnet, but it also allows a proprietary H-Link protocol serial connection which Expedition does support. Then you can output anything you like in the external fields and Exp will do alternating numbers and context switching (pre start, beat, run etc). I've never tried to run a perf processor without a main processor but it might well work. Don't forget the terminating resistors at the ends of the bus. The H2K manual is on Tinley's website and is very comprehensive, including all the details of the H-Link protocol.

For UK raster charts you can do a lot worse than Visit My Harbour's 'unified charts'. They are raster scans of the full admitralty charts, updated annually, with the whole of the UK & Ireland (as in every single UKHO chart) for £33 by download. They work with Exp. The encrypted memory stick version is more, but includes the second years updates... No connection, just a happy customer.
