One of the Buffalo Police channels I monitor is 460.425, P25 analog, part of an LTR Standard trunking system. It's identical in programming parameters to all the other channels for Buffalo Police which I generally receive fine.
One mystery though: On this particular channel alone *sometimes* a reply to voice traffic comes back in what sound like digital encryption. So, Voice "A" says something like "I just pulled over the Wiener Mobile, is anyone hungry?", and Voice "B" will answer "garbly garbly twisted like an audible train wreck garbly garbly'.
Since the beginning of my foray into Buffalo police scanning I just took this as the default nature of the channel. Perhaps the digitally encrypted replies were from detectives who's traffic was encrypted (not that there is any indication of this in the Radio Reference DB or listing -- the channel is just a metro patrol channel like any of the others, but I figured it a rational explanation even so).
I was content enough since it didn't represent a big problem...until yesterday. Yesterday I humored myself with a visit to Broadcastify and discovered that someone was streaming the Buffalo police. For kicks and comparison, even though I have my own police scanner sitting right next to me doing the same exact thing, I decided to listen to the stream.
Suddenly there was communication from the channel under discussion over the actual police scanner. Voice "A" said something and Voice "B" came back all garbled. And, to my shock, the *same* communication followed in the stream (with a few seconds delay) EXCEPT that Voice "B" came back perfectly clear! I was dumbfounded. This meant that I've been putting up with a mis-configuration or a defect or *something* all this time.
I just don't understand *how*.
As I wrote it's a P25 analog broadcast over an LTR standard trunked system. There are at least 4 other channels that don't behave this way. I have the channel programmed in exactly like the others. So the only conclusion that comes to mind is that there is something amiss with the scanner itself ... which is a PRO-6502, a Radio-Shack branded Whistler.
But that conclusion seems a bit unlikely so I'd be interested if anyone has any thoughts on this anomaly.
