We have a “not great, but better than nothing” solution, we are using a backup transmitter on Lee Hill.
It transmits on 145.430MHz with an optional 141.3Hz output tone.
This transmitter does NOT have frequency paired receiver, so you still need to transmit on 144.710MHz!
You can either work split frequencies or have a very non-standard (-720Khz) offset whichever is easier for you and your radio.
This is a very temporary and sub-optimal solution. No need for signal reports, it isn’t going to be great.
Plans are under way to be ready to visit Mt. Thorodin hopefully in about a month after a bit more snow melts.
