I've used only CTCSS in all my GMRS radios, both HT & Mobile. I've run into a situation where the folks I'll be running with use D223N on the trail. I don't know if they have newer GMRS radios or what. I have the Kenwood software and cable so should be good but I thought I'd ask here if it's an issue before I dive in. Daily use I run with no privacy codes in the remote area where we use our radios.
Also wondering why this particular group is using DCS and if you know any advantage, etc.?
Thanks..
