Conventional Priority Scan 996XT

[UPMan]

And, I'll cut/paste from the link fxdscon thought was interesting:

I've owned the Radio Shack Pro-95 for two weeks now. It's a good scanner, except for this one annoying problem. Banks 1,2, and 3 are programmed with local frequencies. I've also set NOAA frequency into the priority channel.

While scanning channels with priority turned off, audio is ok. Scanning with priority turned on, when receiving a transmission, audio cuts out briefly approximately every 2 seconds. I know that the scanner checks the priority channel every 2 seconds but, is this normal operation? Has anyone else noticed this?

Seems the check interval is 2 seconds (but, again, not when on a trunked system).

I am so sorry. I just cannot continue this discussion.

So it won't interrupt a trunked system but will an conventional system? That makes no sense. If it's listening as you say it wouldn't matter what kind of system it is. If that's the case what prevents that? The FIRMWARE!

I will bet you $1,000 AND bring this scanner to your house. I am only 30-45 mins away and you can see for yourself. I am not making this stuff up. I have no reason to.

Seriously, ya can't get dere from 'ere...

How 'bout ya reverse engineer what ya got, start your own company and make a mint!

I suppose you could chat about the weather.

In order for a scanner, or for that matter ANY radio that is not on a trunk system (a priority Talk Group('channel') on a Motorola Type 2, EDACS, and P25 trunk system functions very differently) to check a priority(for example: 146.520MHz) channel, WHILE RECEIVING another frequency(ex:147.240MHz) the radio MUST re-tune the reciever from the current frequency (147.240MHz) and tune the reciever to the priority channel(146.520MHz) while it does the the current frequency being received IS interupted just long enough to determin if there is or is not a carrier on the priority channel, then it tunes back to the channel(147.240MHz) it was origionaly listening to, and resumes receiving it. There is not way to do this uninterupted with a 'firmware fix' it can ONLY be done with a SECOND reciever. What part of this do you NOT GET???

....How do you think the scanner handles only one transmission at a time? Why is that?.....

Because it only has one Reciever (AKA RF section)

....Because it closes the banks on other active channels otherwise you would be hearing every transmission that was active at that moment.....

No way, no how that is going to happen. To "hear" every channel in a 1000 channel scanner it would have to have 1000 recievers inside.

....The scanner shouldn't be listening for channels it should be scanning banks for active circuit. .....

Just what exactly is an "active circuit" It is smiply a fact that the way scanners work is that they scroll through frequencies/channels and listen for traffic, and they have to tune to those frequencies in turn for a period of time to make that possible.

....I just found a hidden trick or bug that no one has ever found.

You have found nothing because it was never there to be found and never will be. You are just simply mistaken about what the scanner is doing/how it is programmed or being operated/the scanner is not operating properly and is not actually checking the priority channel.

And with that I must take a page from UPMan's book and say I cannot continue with this headsmashingwall disccussion.

In my 39 years in public safety and being in the scanning hobby, I've used many different scanners, portable radios, mobile radios and base radios from many different manufacturers. Some were reasonably inexpensive others were quite costly.

A great number of them had priority scanning. Each of them would stop listening to one channel then go to the priority channel to listen for activity. Some radios seemed to handle this feature better in that it was less noticeable when the priority channel sampling was done. About the only time it stood out that the radio went from channel B to channel A is when there was a constant tone on B and you'd hear the break.

What I suspect is happening is that Mesquite WX's radio is doing the priority channel sampling some way that is less noticeable due to the systems he is listening to.

Here's the firmware update that Uniden seems to be so unwilling to produce. You're welcome.

Topic Closed

MesquiteWx:

This is not the first time you have shown your complete ignorance on how a scanner works. This is the same sort of argument you tried to use when you were explaining in a related topic on WX Priority that your scanner worked different than any other scanner produced, even the same model. You get some wrong idea into your head and will not listen to the people who know what they are talking about, and then proceed to completely ignore facts when presented to you.

Since this is really the 3rd such topic you have gotten involved with stating this same failed argument and since you have been a member here less than 3 months I can only assume you are either resistant to learning or are a troll. So, if you start another such discussion and use the same sort of non-logic I will just assume you are troll and you can find some other site to troll.
