Silent activity on 10130?
Silent activity on 10130?
Yesterday and today I've noticed that 10130 is becoming active quite alot. There is usually no broadcast, or there are tones sent.
http://scanner.criten.org/recordings/GR ... -10130.wav illustrates the issue.
Some kind of issue?

Re: Silent activity on 10130?
I'm keen to run a packet sniffer on it and see if its real silence frames coming across or white noise or what - theres some clicks and whatnot in that sample, but its not clear if they are actually coming off the GRN base, or the scanner is just having a fit trying to decode the signal..
Re: Silent activity on 10130?
best of luck guys... it hasn't got anything to do with the GRN.... we are investigating a strange problem that appears to be related to the Broken Hill channel. The only reason you are hearing it would be somebody has reinstated a patch after being told not to- its hard to get good help.

I hear you Matt!
Re: Silent activity on 10130?
The popping is an artifact of the Uniden 396T tuning to a P25 channel. It does not appear to be white noise but rather silent frames (I turned it up quite loud).
Thanks for the explanation Richard - I figured you'd know something
At first I thought it may be an illegal radio user, so I'm pleased that it isn't.
The issue happened again this morning btw.

Re: Silent activity on 10130?
We haven't found the actual cause yet but we did find what was needed to make the fault appear. One of the RoIP links was changed over to the alternate route (most FRNSW PMR networks have a primary & secondary link) this morning, and that keeps the fault in its box... very suss that we have a IPR or 619SRI bridge doing something it shouldn't but we should know that on Monday. I did suspect a Centracom yesterday- but a mate proved me wrong!
