I have not heard Escanaba on the analog channel now for a few weeks. City of Escanaba seems to have a lot of new RID's along with various small town EMS and Fire. All dispatched by 21P911. Was hoping to get someone in Delta County to verify.
It's true that 154.755 has been used all these years. One thing that I can verify while spending many months up there through the years is a inconsistency with the transmitter power on that frequency. With using an external high gain vhf antenna approximately 35 miles away, there were times that their signal barely made one bar on my Pro106 and other/most of the time the signal would be full quieting which was typical. Not sure what the explanation is, but this weak signal would last a few weeks at a time; I know that it has nothing to do with propagation due to the short distance to my location and that 155.715 Delta Co. Fire/Ems was always a strong signal.
Just another question since we are talking about Esci, do they still use 158.835 for public works or anything?
