I have rewired my my 797, bought a gps connector for my Cobra MRF-55 VHF radio so that the HB can send it my GPS coordinates and I can send them to Coast Guard if I ever have to press the DSC distress button.
I have the NMEA pigtail wired in to that connector with the third / red wire wrapped up. I have NMEA output set to "on." However, no gps coordinates on the Cobra screen. &%$#!
I recall seeing something on here that said that the "strings" that output from the HB are atypical. I am just out of luck on this one?
