217.00000 to 217.50000, step of 6.25KHz, DMR Tier III
Depends what you are trying to monitor them on. Scanners don't seem to like 6.25K search ranges for DMR and will often pass over all but the strongest signals.
If you are using SDR & software, you should be able to see the spikes.
If you have looked through the existing Eversource thread, you will read that the system has very little voice as much of the communications is via cellphone or IPad devices. The trunk system does carry a lot of data, presumably for grid status and switching.
