Marine Radio GPS Signal

3 posts in this topic

I have a Cobra MRF45 DSC VHF Radio and put in the Shakespeare 4' antenna. I know now that i want to get the 6 or 8' antenna for the longer range...but i wanted to know about the GPS cabability.

I hooked this radio up myself, but there is no GPS coordinates displayed on the screen. Do i have to have a GPS antenna seperate for this feature to work? I'm assuming it doesn't work of the VHF antenna. Just looking for some insight here. I have the Lowrance internal IGPS Locator hooked up to my boat. Is there a way to connect it to that to get the coordinates? There is 2 wires coming off the radio, but i dont know what to hook them to?

thanks in advance for any help.

The one thing I do know about "GPS" is you need to have a "GPS" antenna to get signal. I would think you have to buy a GPS antenna for the correct application. I would contact Lowrance and see if they ave an adapter for this.

Just my 3 cents shocked.gif.

You have to interface the radio and the GPS via NMEA0183, colors may differ from various manufacturers. Read your manuals and determine which wires to connect. GPS and other navaids will send out signals called sentences, your radio will be able to read the date, time and position sentences. NMEA0183 is the communication protocol standard to marine electronics. There should be diagrams,some showing which electronics use which wires, normally for a simple radio connection it is a positive and negative and a signal return,(NOT 12 VOLTS) usually a green, yellow and blue wire, but read the manual first, if you don't understand it, bring the books to an experienced electronics retailer/installer, and have them show you or call the manufacturer for technical assistance. I have no experience with those makes of electronics. But they should be very similar if not exactly the same wires.

      So it was a legit test then. Yum maple syrup nothing better! Stay safe if you venture out. Things are getting sketchy.

      What are you using the rod for?  Bass if so what lures are you going to be using, the reason I ask is that if you're using a Jig you're going to want to up your line weight to something like 17#.  You mentioned that you're new to baitcasting, a couple of tricks I used when I was first learning to cast to help manage backlashes, is set the tensioner knob so the lure just pulls out the line, then make a long cast and pull off another 20-30' of line from the reel, place a piece of electrical tape across the spool and reel the line back in. Now the backlash will only go as deep as the tape.

      Sorry for the late reply, but no, the first 5 to 6" was soft but the rest was solid. I've been busy in the woods making maple syrup that I haven't got time to get out. I hope to get out tomoorrow.

      Thank you very much! I appreciate the information. I think I will run straight fluoro then.

      I have been using the Alberto knot and really like it, it's easy to tie and one of the strongest knots when going from braid to Fluoro.  I mostly have been using that knot on a spinning rod, for baitcasters I usually just like to run straight braid or straight Fluoro.
