Assuming that I cant connect my new DSC VHF to my existing GPS NMEA system (its a long story previously posted here) what is the cheapest way to get NMEA 0183 to my new VHF
GPS feed to DSC VHF

I use a garmin GPS12, bought it reworked from the boat show from MES. Use a cable from maplin with a 12v adapter. Easy peazy, h/h GPS are even cheaper now.

Not sure about VHF but I needed to get nmea to my inherited old Raytheon chartplotter, which needs an active external antenna. I opened up the plug on my handheld garmin power lead and soldered a twin core cable to the nmea pins.
Hey presto - position data on the chartplotter without the expense of an antenna

As I recall, you were trying to connect your Magellan GPS to a Silva repeater, a Standard Horizon DSC VHF and a laptop. In an emergency, the DSC position is rather important so, if you're looking for the cheapest solution, it would be better to use your Magellan to feed the DSC and the repeater, and get a cheap GPS feed for the laptop. You can get USB GPS receivers for only a few quid on eBay. Or buy a cheap used handheld and hook that up to the laptop.

[/ QUOTE ]Not necessarily, in the previous thread it was explained that a connection to the laptop could affect things even with the laptop switched off. Have you tried disconnecting the laptop?
Additionally, do you know that the DSC isn't faulty? Have you connected your Magellan only to the DSC? You need to methodically work through the options to track down the cause of your problems.
If you end up needing a separate GPS feed for your DSC, I wouldn't recommend buying cheaply - go for a decent standalone marine GPS NMEA receiver - it'll cost £100-150, but will be a safer solution.

Today disconected laptop,repeater still not wrking. DSC on its own is fine with nmea as is existing setup without vhf

Not sure if this helps.
I tried for ages to connect my Navman 7100 VHF to my Northstar 550 GPS with Zero results to the point that I was going to send them back as they are both made by the same company, and the Northstar is identical to the Navman GPS but with differant grey buttons.
However by luck rather than judgement I had to 're-set to factory setting ' the GPS to recognise my local C map as it would not when I put it in at first, then clicked Nmea and Bingo everything works great and GPS position is on the VHF also.
Technology is a wonderful thing when it works!

Just a thought, but have you got the baud rate set properly (data exchange speed).
If it isn't then gps won't talk to dsc etc.
