OK, I am open to learn new things. If I say I want to talk to you on "channel" 19, is there a way to communicate if, or if not, there is a PL filter involved?
If we agree on a "channel" AND a PL filter what would that be called?
And if we use that same combination over a period of time do we have to continue to say "channel 19 with code 141.3" or could we just say meet me on the "trail" channel?
