Are you referring to the PL tone? I find it's more noticeable on Gunbarrel and Mead than it is on Thorodin (which has the lowest frequency PL of the three).I felt bad because I kind of bad mouthed (not on purpose) the conventional system that Boulder County uses, talking about a "hum" I hear on it. It seems like since they went to narrow band, there is very little of the hum, except on certain conventional radios where there is like a chunk noise, and a bit of a hum along with the audio.
I've logged a couple of radio IDs affiliating or getting a channel grant for 9100 (ignoring 385013). I also recorded the audio to identify which unit it is.Anyone ever catch any radio IDs used by Erie PD in relation to this as mentioned earlier?
