If your intention is to see if Evans is using NXDN, all you need is FMP24 and DSDPLus open. You really only need what's shown in my video to determine if the system is active and what flavor it is.
After FMP24 and DSDPlus are open, I focus on FMP24 and enter a freq, that I already know is NXDN. Signal shows on spectrum with a narrow bandwidth. So I reduce to FMP24 bandwidth down to 4khz by hitting b on the keyboard, since I am focused in FMP24.
I verified NXDN decoding was enabled, which it wasn't. Once enabled, it instantly identified the signal as Nexedge48, and displayed the system and site numbers, the Ran and the neighbor site in the next county.
