VHF/GPS Combined

Does anyone make a combined vhf and gps unit? If not why not? Being an ex-electrician I like to keep things simple eg why connect two independant units if one will do the same job.

Thanks but not quite what I had in mind. What I would like is a vhf/dsc with a built in gps so you don't need to link it up to get a gps signal. No plotter or fancy crap only a stand alone unit that gives position in the event of a distress message being sent.

Uniden has a unit that is a combo hand held GSP VHF radio. Seems like a very slick unit. Unfortunately it appears that there are issues with the marine maps. I guess you can only load one map in at a time. Here is the link to the Uniden Mystic VHF/GPS Mapping Marine Radio unit:

It's a wonder nobody does what you mean. No need for a silly display or anything else. Would add about £10 to the cost of a radio. Ideal for a hand held!!!

I may be at the wrong end of the stick but DSC handhelds used to be available but aren't anymore (possibly only in the EU?). This was because if you hit the red button the MMSI broadcast was that of the parent vessel- the rescue services would be looking for the parent vessel rather than a dinghy or a man in the water etc.

Jimbo or Jon Brooks should be able to correct me if I'm wrong here?

The reason that the Simrad DSC hand held was removed was not for the reasons mentioned, sorry .

The units were actually given their own batch of MMSI numbers so they could be seen as hand helds if they sent a distress.

They were withdrawn as it was felt that they were not a full DSC unit and could not do the same as a fixed unit. with this in mind it was felt they did not meet type approval. The other downside was that the GPS info was only correct if the unit was in its charging shoe, onced removed the info would be out of date very quickly.

Like the Uniden the SH combination will not get through the CE marking part of type approval.
This is not to say that companies are not lookking to produce units that will.
It is far easier to get a radio approved for the US market compared to the EU market.

Codders, £10 is a bit low. not only do you have to consider the input of the device but also ensuring that the GPS engine does not effect the rest of the electronics. GPS engines make a lot of noise, electrical noise, so can be hard to fit inside a unit.

Can't be difficult though - most commercial EPIRBS can already broadcast their own position...

As a suggestion for Alan's original question, some of the packaged GPS antennae should do the job (eg Holux etc). Around £50-80 and they pass NMEA, so you can connect to VHF unit in the same way as your GPS. Just make sure it's serial rather than USB output.

Having said that, you can probably pick up a cheap discontinued model handheld GPS for not much more and get a lot more functionality.

Codders - if you look at the premium of GPS vs non-GPS EPIRBs/PLBs, that's the sort of extra you'd be paying for a GPS equipped radio.
