Call me thick if you like /forums/images/graemlins/blush.gif
Trying to sort out the GPS to VHF here, does the NMEA out from the GPS go to the NMEA in on the VHF, and NMEA in on the GPS go to VHF NMEA out ?
All these ins and outs are confusing and my mind isn't quite working at full steam today /forums/images/graemlins/confused.gif
 
I think that the NMEA out from the GPS goes to the NMEA in on the VHF and that is all - it is a one-way conversation (like talking to wife /forums/images/graemlins/grin.gif). Your VHF has nothing to tell the GPS. The NMEA out from the VHF can go to NMEA in on a plotter to show the position of your DSC friends (if you have any /forums/images/graemlins/tongue.gif).

What model GPS are you connecting to what model VHF?
 
There may be value in having the VHF send to the GPS. I think some sets may send the location from a received DSC call to the GPS / chartplotter so you can sail to the emergency site to do some rubber necking. Very much depends on the sets and the sentences they send/receive.
I haven't made the connection myself though. :P
 
Thanks Roger, knew somebody sensible was here /forums/images/graemlins/grin.gif
It's John's GPS 72 and David has already told me which pin to use, so that should be easy enough (he says, knowing something is going to go wrong /forums/images/graemlins/blush.gif )
Can't remember what VHF it is but the NMEA wires are marked so should be sorted now
Had a feeling I had done it like that in the past but couldn't quite remember and didn't want to muff it /forums/images/graemlins/blush.gif
 
I know I'm late, but here goes anyway.......




You are thick!




Happy now? /forums/images/graemlins/smile.gif Why yotties want to have all these complicated electronic bollix on their boats beats me?? /forums/images/graemlins/confused.gif

Never heard of the KISS principal?
 
Keep

Stoopid

and yes, you're late, now sniff off /forums/images/graemlins/grin.gif

Main reason is that I have a DSC set, and a GPS on long term loan so may as well use it. Seems to me that if you use what you have but get by without if you don't, then you're just being sensible really. But then that's just me /forums/images/graemlins/wink.gif
 
Electronics, wont make you safe, only good seamanship will do that.

Relying on electronics as an aid to safety is purely delusional.

Sniff off??? what's that?
 
Ah but then we get into the old argument over using modern aids or not, and I'm of the school where I would rather use than not. Good seamanship only comes through experience though, no argument there
 
To my mind people that fill their boats with electronics, are hoping that the electronics will absolve them from learning seamanship and paper navigation, there are even twonks on here that have a chart plotter at the helm instead of a compass!.....

Anyway, you must do as you see fit. each to their own as they say. I will shut up about it now, because some twat will be along in a minute to tell me I'm a troll.

"Kiss" and "Chrusty" in the same thread is a bit worrying for me......

Uh? /forums/images/graemlins/confused.gif
 
Chrusty, I don't think anyone here is going to call you a troll at all, having fallen victim to the chart plotter at the helm thing in the past I know what you mean /forums/images/graemlins/blush.gif
Steering by nintendo doesn't work /forums/images/graemlins/grin.gif
They do have uses though, but mine is mounted at the chart table and can be viewed from the cockpit if needed. Personally I would love to learn to navigate using a sextant, well anything with the word sex in it has to be good /forums/images/graemlins/laugh.gif
But the chances of me ever having enough money to buy one are very slim, so no real point learning how to use them. Navigation in The Wash can't be done using landmarks either because there aren't many things you can see when out there to give a fix. Might try it next time out though, just to be sure. Think someone said there are one or two things but I've been too busy sailing to look out for them so far
 
So what do you think sailors did before GPS? In the Wash or anywhere else, and I am not talking about Sextants, yes, even cheap ones are pricey, and of limited use for coastal navigation.
