I am a ham noobie and I'm trying to maintain comms with my XYL using two 2m/70cm dual band HTs well outside of their simplex TX range while I am mobile. So far, I have been able to accomplish this by either: 1. Receiving on the repeater freq where she is located and TXing on the closest repeater to me. I need to change the repeater on which I am TXing when I move out of range, so she keeps her HT TXing on her local repeater and sets the other channel to scanner mode (of area repeaters programmed in memory) waiting for my TX. 2. I can use an echolinked repeater, but I would prefer to be as much off grid as possible. There are non-internet-based linked repeaters in my area, but I don't know how to use them. When I TX to one of these repeaters, will my signal will be TXed through all of the linked repeaters? Do I have to specify/call a specific repeater using DTMF? Thanks!
