• 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:

The local public service officers frequently move off the regular frequencies to "tactical" frequencies when working an emergency. I find nothing shown in the database identified as tac frequencies. Is there someplace to find these? (I live in Hood Co., Texas).

Thanks.

Welcome kz5x.

Which agency? For Granbury, 453.5500 is tagged as a "Law Tac" frequency in the database.

Some of those officers could possibly be using the statewide mobile frequency, 154.9500, as a 'tac' or car-to-car channel. In some systems, they'll use the repeater input, or output, frequencies in simplex mode (not going through the repeater). This is usually low power, and you'd have to be very close in order to hear it.

Remember that the only thing showing in the database here is what's been submitted as active. Pull up Hood County, then click on the link for FCC licenses, and you'll find more listings than are shown on the main page. One or more of those could be active, just not reported.

Thanks Tom and Hiegtx. Agencies are PD, DPS, SO, and FD. All seem to use some kind of tac channel. I suspected they might be using some variation of the repeater freqs in simplex + no tone to not key repeaters. Will also check your suggested freqs other licensed freqs in county and listen for activity there.
