There is a way on CHIRP to lock out the TX function. Turn "Duplex" off. It should lock the TX mode out.
Well THAT was flippin easy. SMH. Everything I found online was 5 flavors of convoluted. If rep actually worked right now you'd get lots of it. Thanks! I happened to have my config open still so I turned TX back on and set FRS1 to that and whadda ya know? I couldnt TX on FRS1 but I could on FRS2. (which wasnt set to duplex off)
Gotta love open source documentation/support.
