• 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:

I got a weird one...I stumbled across what sounds like a tow company on 451.625 Mhz, no tone of any sort, definitely analog as a much OLDER Bearcat scanner first heard it.

When searching the RRDB and the FCC ULS, nothing hits locally for that frequency that would indicate a tow company. The "closest" thing is Marin Municipal Water District, DEFINITELY NOT THAT!

Anyone else in the Santa Rosa area able to hear this? It's LOUD in Cloverdale!

Not sure if LTR would be analog like this, IIRC it has a bit of digital to it being trunked, but that's about the closest I'd be able to hear is Geyser Peak.

I'll wait for others to chime in as well.

LTR is analog and it won't show any info on Uniden scanners. On most GRE/Whistler models it will show the LTR channel info.

Don't know if the newer Uniden's do it or not, but I know on older models if you created a 'quick search' range with the 'control channel only' function on (though LTR does not technically have a control channel), some LTR info would show up if there was activity on a frequency. So depending which scanner you have, you can try that.

I wonder if you are receiving an image, if you hear it with a Bearcat and the GRE/RadioShack. No PL I'm inclined to agree with it being LTR.

What model Bearcat are you using.

It first came up on a BC350A. I then put my GRE/RadioShack into search mode around the same frequency range.

This is the old analog LTR on Geyser Peak which is a separate system than the IDAS system. I cannot speak for the validity of the license for that location but my customer information shows this as an active channel.

Likely Site 12, has had additional frequencies added to it
Just a wild wild guess
That might be plausible.

Wouldn't LTR show up as TG: xxxx though on the GRE scanner like other systems do...?

Either way, ALL I hear is tow truck traffic on it.

Do you have a good pair of headphones or an external speaker with decent bass response?

If so, hook them up to the scanner and listen for a low warble during transmissions. The low warble is the LTR signaling data.

I do not. Oh well! I'll just chalk it up as the LTR system with only a tow company being heard!
