TRX-1: Signal Strength, but no squelch break

[jprejean]

I'm just starting to get the scanner set up and I noticed that I often see max signal strength indicated but hear no sound. I get lots of hits of course and so far I'm loving this scanner, but sometimes it just seems like it is picking up a signal (5 bars most of the time) and no audio, does not stop or hit likes it seems it should.

Are you scanning a trunked system? If so my TRX shows the signal strength on trunked system all the time, as it is listening to the control channel. If you are not monitoring a trunked system it might be one of your frequencies is actually using a different mode (P25 vs Conv, DMR vs NXDN, etc) than you have programmed.

I believe the "T" in the display is indicative of receiving a trunked system.

It would help to know your city, county, and state, and which system or systems you are monitoring. Did you create a configuration file or are you scanning from the database?

It's receiving a digital signal and will dwell on it for the time you have set to the system. During that time it will show the signal strength and that T and will only have audio, and show it's information, if there's an ongoing conversation.

I'm located in Virginia... It's a database generated by a TRX-1 utility called the TRX-1 Handheld Digital Scanner Programming System- CDAT. It generates a database by location with Trunked Groups, Conventional Freqs, Analog, P25, based on a State/City or ZipCode. I'm just getting started, planning to generate config files eventually.

Thanks, makes sense.... probably need to play with the time configuration.

Without knowing your city and county and the agencies you want to monitor, it's difficult to be able to help. We need to check the database to determine what could possibly be a problem such as simulcast distortion or encryption and the sites you are using. I have the TRX-1 EZ Scan software also. If you attach a configuration file, we can check it for errors. Click on Attach files and Open the file.

Make sure your squelch is set to about 9 o'clock.

If you in the scanners menu under Global setting set the IF Out to Speaker/HP you can actually hear what the scanner are receiving and can determine if it's interference/distortion or a nice sounding data signal. In each system you will have a dwell timer that are set to 1 sec as default. That's how long it stays on a digital signal and wait for a conversation to start. If it stays longer than that then it might be data information being sent, text or data that it cannot decode. Uniden scanners can get stuck on those channels and I don't know how Whistler scanners handle those situations. My impression are that Whistler has a more refined way of decoding digital signals and shouldn't get stuck on data info channels.
