Correct Frequency for Houston Co Sheriff

[charlied]

Can anyone give me the correct Frequency for Houston Co Sheriff.
They list a UHF frequency but there is also info on the database page that references a trunked 800 system.

Thank you.
That's the one I'm listening to and getting the squelch break every 8 to 9 seconds.

It's a LTR system and it sends out a burst of data every 10 sec or so, Years ago a program called
LTR analyzer would decode the data and show the channels (?) assigned, but not the frequencies.
I haven't used it in quite a while and I've had a couple of computers die in between but I'll try and
find it just for something to do.
Can you tell me the freq. that Hartford in using? About 3-4 months ago someone was looking for
that freq. I looked at all the fcc and radio reference info and listened but I couldn't find them. I'll
look in the archive section and find him and see if he still needs that freq.

Hartford has gone to NXDN.
Their frequency is 159.255 with RAN decode 10.

Any further on the squelch break I am experiencing?

LTR breaking squelch

I don't know of a scanner that will null LTR squelch breaks. But my last scanner is a BCD996T and it
doesn't allow but for RF and audio tone squelch to be set. I've been using a RTL-SDR usb radio for the
last 4-5 years and when I listen I use HDSDR software and It has an audio filter that I slide up to filter
out the LTR data sent along with the audio and I slide the squelch up to where the LTR burst won't
break the squelch but regular conversation will. Crude but it works for me when I listen to Houston
County. Newer scanners may have an LTR type squelch system, don't know.
