Hey Denny,
I am running into the exact same problem as gator did with Passport on page 1 of this thread, only this time I am using an RT820 tuner SDR (he was using line-in from a Pro-92 discriminator tap). In both cases the system messages pass the error correction test, but appear to be random in nature - different DCC, Home Site IDs, Talkgroups, Message Types, etc.
Here's an example from the same conversation on the same talkgroup:
Code:00:00:03 Passport Pass CALL TG:43025/**UNKNOWN** SITE:077 CHAN:0139/0.00000 FREE:1259/0.00000 101011000 10 00010001011 1001101 1010100000010001 0000 10011101011 00011010 [b](0x158) DCC:2 GOTO:139 HSID:77 TGID:43025 Type:0 FREE:1259 CRC[/b] 00:29:10 Passport Pass CALL TG:23469/**UNKNOWN** SITE:029 CHAN:0446/0.00000 FREE:1708/0.00000 101011000 01 00110111110 0011101 0101101110101101 0001 11010101100 01001010 [b](0x158) DCC:1 GOTO:446 HSID:29 TGID:23469 Type:1 FREE:1708 CRC[/b] 00:30:19 Passport Pass CALL TG:58997/**UNKNOWN** SITE:002 CHAN:0161/0.00000 FREE:322/0.00000 101011000 11 00010100001 0000010 1110011001110101 0000 00101000010 00010011 [b](0x158) DCC:3 GOTO:161 HSID:2 TGID:58997 Type:0 FREE:322 CRC[/b] 00:32:06 Passport Pass UNKNOWN SITE:041 CHAN:0392/0.00000 FREE:747/0.00000 TYP:12 TG:40258 101011000 11 00110001000 0101001 1001110101000010 1100 01011101011 00011011 [b](0x158) DCC:3 GOTO:392 HSID:41 TG?:40258 Type:12 FREE:747 CRC[/b]
The messages also don't seem to be decoded in real time. They lag behind the conversation (sometimes appearing when nothing is being received at all). I also don't get any "IDLE" messages when receiving the idle bursts every three seconds (which should be type 1 messages indicating the registering LCN and site numbers of neighboring sites). As you can see above, the talkgroup ID varies during the conversation, as do the site number and DCC (which, like an LTR area bit, should stay consistent throughout the system).
I suspect the error is around where the program turns the subaudible data into binary symbols. The 0x158 sync pattern (101011000) correctly appears at the beginning of each OSW and the error detection says "Pass", but what follows doesn't make sense.
For reference, I found an old thread about decoding Passport OSWs I contributed to here (although I've since forgotten everything I knew about it): http://forums.radioreference.com/tr...oding/188-ltr-passport-decoder-project-4.html
Unfortunately not that I can see. Each time they key up (same talkgroup based on conversation, same frequency) it appears as a different combination of DCC, GOTO LCN, HSID, Talkgroup, Message Type and FREE LCN. So far I haven't seen a pattern and it appears to be random. I'll post a screenshot later tonight.
Thanks again!
Hi.
I've got several Nooelec R820T tuners. They all work with SDR# & Unitrunker, but I am unable to get them to work with SDRTrunk.
I have made sure I am using the latest version (with R820T support).
I have reinstalled the latest version of Zadig several times.
Have performed reboots, and restarts of SDRTrunk.
I have also plugged the SDR dongle in, waited 2 minutes, then launched SDRTrunk to see if it would work. All to no avail...
I simply get the following message,
"SDRTrunk does not support RTL2832 with [UNKNOWN] tuner". See image below.
Probably the oddest part of the story is, I did get it to run the very first time I tried it, and was able to monitor an LTR system for a couple of hours . I just haven't been able to get it to work since!
I can't imagine it is a driver issue - since all the other software is working fine with these tuners. I don't really know what else to try at this stage, but I'd love to be collecting some info on the local LTR networks that are not well documented in the RR DB.
System is an i7 laptop running Windows 8.1.
Anyone got any clues on this?

The error is being thrown when SDRTrunk tries to claim the dongle in order to determine the tuner type. A libusb error #12 means that SDRTrunk couldn't claim the device.
Probable causes are A) another application or process has already claimed the dongle or B) your user account in Windows doesn't have privilege to use the dongle.
Since it worked for you previously, I would suspect that A) is the cause. But, all of the troubleshooting steps you've described are what I would recommend to attempt resolving the issue.
Do you have any software applications set to autostart when Windows boots that might be claiming the device?

Rabrol,
I posted a new sdrtrunk build to the download folder that has added DEBUG logging to help in figuring out which specific operation is causing the error. Could you please download and run that version and post the application log file to the google groups support forum.

Your application log file should be stored at:
c:\Users\retka_000\SDRTrunk\logs\
I'm going to be out of town through Sunday afternoon with CAP, but I'll dig into the log file when I get back and see if we can get SDRTrunk working for you.
Denny
Great project! Unfortunately can't try it because local services are using NEXEDGE equpment, so consider this as one more request for NXDN decoder (take a look as this....it may help you NXDN Control Channel Decoder - Anritsu America )![]()
I just started on an fsk4 decoder for p25, so nxdn shouldn't be too far behind that.
