As Kruser said " Phase I only at this time. I see hiegtx is watching a Phase II system. Maybe that's the difference".
THIS - Uniden handles phase2 differently than phase1. I do not remember exactly why. I know Paul ( Upman) explained it, but don't remember. I think there is a data bit that may show in PH1 that is not present in PH2, but just a guess.
I only have PH1 in the area and never hear anything on the Enc channels. Nothing on Proscan either. I run Pro96comm on a 325 to log and can clearly see the Enc channel.
Are some users possibly thinking that signals badly affected by LSM are encrypted? A signal badly affected by LSM can sound just like encryption even though it's really in the clear.
For these instances, ProScan will usually log them along with the UID. But... if the scanner see the E flag, the Unidens basically skip the conversation like they should and continue scanning and ProScan will not log anything as the scanner never even really stopped anyway.
I do see Uniden's pause at times for a very brief time period when they encounter an ENC signal but more times than ever, they totally ignore it and keep on looking for the next signal you can actually understand. This is the preferred behavior in my eyes.
The above can all be seen with the likes of Pro96com as you mentioned which is exactly how I keep an eye on enc traffic. It works great plus I sure don't need to hear the sound of gibberish coming from my speakers while the Uniden is missing clear traffic that would be missed if it is stopped to listen to ENC noise.
For those that want them to stop, Uniden would need to offer a setting to allow that in firmware. This has been asked for many times but has never been acknowledged by Uniden. Something like that would probably be welcome by all so the majority of us don't need to hear the ENC signals that do nothing but tie up scanning for clear signals. A simple electronic ENC pause on/off switch in the firmware would suffice.
Of course
@n1chu will say that is against FCC rules.
I really don't know why all my running instances of ProScan have never logged encrypted traffic from a Uniden but they have not. At least not on any of the Phase I or conventional P25 traffic I monitor.
I have nearly two dozen Uniden models at my disposal ranging from the early P25 models to the SDS series and they all behave the same in regards to nothing at all being logged by ProScan when an encrypted signal is seen.
They all also skip over encrypted signals with usually no pause at all. If the radio does not even pause on an encrypted signal, how the heck could ProScan log it! There's nothing to log so naturally ProScan would not log anything.
In all the years that Uniden models could receive P25 and all the years ProScan has logged those models, I've used virtually every version of ProScan ever released along with all the Uniden models I own and have never had them log any encrypted traffic in ProScan.
It's possible with the really old models that used the P25 card like the 796D etc., that they may have stopped on encrypted signals but it's been a while so I can't remember. I guess I should hook one to a computer and see.
If there's a setting I've overlooked in the radios or in ProScan, I'm all ears so I can change it and see if ProScan will then log this traffic!
Something tells me I'd have discovered this by now if this were true however.
One question, if a system uses other than AES encryption, how does a Uniden handle that? That being for P25.
For DMR signals, none of my DMR capable Unidens pause on encrypted DMR signals either. And no, they don't log to ProScan either if a encrypted DMR signal was detected!
I will confirm that is true with Basic Privacy mode as well as AES encryption for DMR. I watch DMR and NXDN signals with DSD+ and it will see the encrypted traffic on DMR and NXDN systems but the Uniden's simply ignore this traffic as well.
I don't have a ton of NXDN traffic here and most is in the clear but for the little that is known to be encrypted, the Unidens never pause on those signals either, just like they work for P25 and DMR.
