    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:

Paul? Is there any way to turn the Digital End Code on for a specific system?

Us folks in the DC Metropolitan area that monitor the Montgomery Co MD TRS have developed a new problem with the radio hanging after a comms. Often, you will hear another TGID talk while this is hung. Eventually, like 1-2 minutes later, the radio resumes scanning on its own if there is no talk on any TG. I have identified 4 or 5 different TGs talking while the scanner is hung on a totally different TG. This is being reported by many HP-1 owners on the local Yahoo group.

I think it is happening because of changes the techs are doing to the Quantars in prep to rebanding later this month, but it is extremely annoying to have to hit the bottom bar twice to get it to resume scanning.
I have turned on Digital End Code on my 396T and 996T and they no longer hang.

Please help!!

JK :(

Digital End code is always on (cannot be turned off).

You should also be sure that squelch isn't set too low.

Thanks, Paul.
I am pretty sure it's a system problem related to rebanding preparations. I really think it is a Quantar programming issue, but it does not occur on my other 2 radios (396T, 996T) with end code on (which it was not, previously). pretty strange!

FYI, the squelch is at about 5 bars to work with the conventional systems I monitor, but should not affect digital truncked systems, does it?

When set too low, if the scanner misses the end code it will hang on the channel with open-squelch noise and "bleed" over to the next comm on that voice channel. It will also take much longer for the scanner to determine the control channel for the system.

When set too high, if the control channel signal is not strong enough to break squelch, the system won't be scanned. If it is strong enough but the voice channel is not always strong enough, you'll get interrupted comms.
