[aprssig] Kenwood D7 not working with Garmin 76C

[Janet Kirk]

Is anyone using a Kenwood D7 with a Garmin GPSMAP 76C? (or maybe its sister 
60CS)?

My older GPS III+ drove the D7 fine, but my new 76C will not cause the D7 
to send a signal. I checked the 76C output on a terminal program and it 
looks fine. Garmin tech  says the signal level/voltages are the same in 
both units, although the 76C users a newer NMEA spec.

Is it possible that the Kenwood D7 will not work with the latest NMEA specs?

(Also, When checking it with the older III+, I  notice the D7 will continue 
to send out the last posit data it has received from the GPS, without the 
warning that it's an old posit, even after the GPS is turned off. That 
seems like a D7 programming glitch, if true.)
