..in the specs it again gives reference to hooking it up to a fixed mount gps, so I'm not sure why a person would do that if it's already built in.
I believe the radio can output GPS information for use by appliances on big boat-- for example a chart plotter-- not much use for kayaker.
...it gives reference to a $65 3 yr flat rate, so I'm assuming that is not a flat rate of $65 per year but for all 3 years.
The warranty is 3 years. If something happens after that, it costs $65 to fix, whether its a broken knob or busted LCD or flooded radio. There is no charge for DSC/Distress.
for someone like myself I would need to know if it works in Canada (Quebec in particular).
...same with the weather alerts are they in both languages ? (I assume they would be just like a VHF if your up there.)
I am not sure you want to get an MMSI from Boat US if you are using it in Canada. The databases are not merged. In fact any American who wishes to transmit in Canadian waters has to pay for an FCC license and has to get an MMSI from the FCC, afaik. I do not know if the Canadian agencies have deployed the equipment to receive the distress call.
In America, its a big deal and the program is called Rescue 21. Also, the Canadian frequencies are different, and you have to setup the radio to use the Canadian channels. Most VHF's support US, International and Canadian channel numbers.
(I would want to know how many days it can send a distress call)
It will continue to send distress calls until someone acknowledges the distress or its batteries die. From what I read, any boater will receive your distress call, as well as the Coast Guard...its like peer-to-peer rescue. Finally, larger maritime vessels have radios which hear your distress call and retransmit the distress call...again like peer-to-peer data sharing.
I like the feature of being able to call kayaker buddy if you know his MMSI number. I think you can set the radio to go to a chat channel like 67 or 68 after your buddy's radio acknowledges the call. Also, if that buddy has permitted his radio to do so, you can query his position and get a distance and bearing...might be useful for a leader and sweeper in less than ideal conditions...well Ill just admit Im a big gearhead, lol.
