• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Don't assume that it's related because of the system ID. That ID of 00A is pretty common amongst Harris P25 systems as a "default" ID that sometimes does not get changed.

407.0750 was reported as an EDAC system [never saw anyone ID IT] back in 2012 for Austin

No one is assuming anything. I'm well aware of how many systems use that SysID and WACN. I'm simply hypothesizing that they might be related due to the fact that there is also a national laboratory in Houston.

I would also point out that I obviously did not just look at the SysID, which would be foolish given that there are 81 identified systems in the RRDB using that SysID of 00A. However, using the combination of WACN and SysID, which is the correct way to research something like this, that huge list is whittled down to just three systems:
  • A system in Canada, so we can scratch that off the list.
  • A system for the Aerospace Data Facility East in Virginia, operating in the VHF band and which already has RFSS 1, Site 1 identified with a control channel of 172.350. That conflicts with the OP's observed adjacent site list of RFSS 1, Site 1 with a control channel of 408.625. Scratch that one off the list, also.
  • The Los Alamos National Laboratory system, having a site identified as RFSS 11, Site 11. A DOE installation operating in the federal UHF band, same as the other sites the OP has observed.
My opinion is that it's worth checking out the other DOE national laboratory locations to see if any trunked sites are discovered with a matching WACN-SysID and whose frequency usage and site numbering fit the same pattern.
