yeah my bad, i tend to group things together that really ought not be.
i have a bc345 or 365 uhhh, well analog 500ch base station with a VOX recorder hooked to it. 364.2 is plugged in on it and occasionally ill get something from that, which is what i presume it was, the location of the scanner being such that the signal has to be close or very strong.
it was a standard EAM(type) message, but the dudes call-out speed was a bit faster than normal, i inferred his tone more serious, and a constant tone played through out the whole time at a volume loud enough, that any louder would have interferred hearing the guys voice. i wasnt sure if it was a deliberate warning tone, like the "this-is-unencrypted-*beep* " you hear on SINGCARS radios operating in the clear, or if the tone was some equipment issue.
sorry for the imprecision.
