[aprssig] gps/tnc linkup

[Mr Jeffrey L Ross]

hi folks, i have one of them gps cables i got from aea that has a phono plug 
that suppose to plug into a gps, anyone seen a gps with a input/phono plug? 
i have not, anyway wanting to try a garmin extrex hc series or another 
garmin gps that i have to a kpc3+ and wondering how the easy way to do it.
i know im going to have to cut some wires to the gps,s to get the input and 
output for the device. does anyone have any ideas the best way to go? 
wondering why no one is selling the cable to hook  the gps to tnc besides 
the aea phono plug unit. thanks in advance. just would like to give gps/tnc 
aprs a try tracking a vehicle. 73 kc8gkf
