I can’t hit the local analog repeaters without using the higher power on my HTX242 (yeah it’s old but it’s what I got), the HT I have is DMR (and analog) but I would like to use low power DMR to make the battery last longer. I want to do something like this (see pic). Anyone done something similar?

Note I already have moded the HTX for COS output and made a control interface using a ESP32, I also have a Pi-star hotspot that I could repurpose until I can get another.
