Need help with PDW 3.12

jfhtm350 · Jan 9, 2015

Cant get the dern thing to work.I have a tapped radio hooked to the line input on the sound card. I can run DSD+ so its not the radio or tap. However I dont know if the digital signal is a pager signal or something else. If I post an audio file of the signal, is there some way someone can run it through and see if it is a pager signal so I can start looking to see if my settings are wrong?

post it up bud someone will figure it out

This is descriminator audio recorded with Audacity. I cut out the static in between the digital noise. The digital noises do not have a set time in between transmissions but they are random. It is a wav file. I didnt know if an mp3 would suffice.

It doesn't sound like poscag or flex according to this page

I decided to try out the ACARS part of it and it wont work either. I can hear the ACARS sound coming from the scanner through the computer but nothing. I have a known ACARS recording so I put it on a tablet and played it through the line input of the computer and nothing.

I even tried all this on a Vista laptop through the mic jack (there is no line input) and still nothing. Its like the program is ignoring the soundcards. I've noticed the meter in the top right corner doesnt move at all. I read somewhere that it is supposed to move with static. I think I will try version 3.1 and see what happens.

That's NXDN, I think NXDN48 . Let me run it through DSD+ and let ya know.

It is definitely NXDN48. I had to convert from 44khz to 96khz so the raw audio was not optimal, but I could decode it.

TG 1401 unencrypted
TG 1102 encrypted

The first little bit of audio was TG 1401 unencrypted. Most of the rest was TG 1102 encrypted.

DSD+ lkes 48khz / 96khz wav files.

Jamie,
That is the Sevier County NXDN trunk system you are hearing.
1401 is the Gatlinburg Police talkgroup
1102 is Sheriff's encrypted talkgroup

Oh. I thought I had run DSD+ on that freq but I cant remember. There are some more digital freqs in the paging band but they were inactive when I made a recording. I'll have to look around again. Well at least I know what that freq is. Thanks guys.

I downloaded pdw3.1 and still get nothing with ACARS. The meter in the top right does move but barely (from the 1st dot to almost the 2nd dot). I think I lied since it barely moves with v3.12. I can jack the volume all the way up and the meter wont go anywhere. When I put the volume all the way down, the meter is dead still. So it looks like the program is seeing the audio but it isnt high enough. I'm fixing to put the program over in the recycle bin and put a 10pass DoD erase over it. Hehe. Maybe I'll try another program.

jfhtm350 · Jan 26, 2015

Well I figured out why PDW wouldnt work. You have to have both left and right channels hooked up to the descriminator. It doesnt work with just one channel for some reason. Maybe this will help someone else.

foxtail · Jan 29, 2015

Maybe your not setting something up right...disc. does work with sound card. Disc. tap is only one tap not two. You could try a stereo plug but most taps I have done are mono...meaning just one. Ring and tip. But then I do also run with a real com port and a 4-level decoder from back in the day.

jfhtm350 · Jan 30, 2015

It started working after I wired my descriminator cable into stereo. It was only wired up on the tip. I dont think it was just a coincidence but anythings possible and it works now.

foxtail · Feb 26, 2015

Question, do see flex pages for A,B,C,D frames or just pages from say A or B? Wondering if the stereo tap will run both channels.

jfhtm350 · Feb 26, 2015

I can receive flex signals with the tap wired to both left and right channels if thats what your asking. I didnt notice anything about frames but it seemed like it was working fine. I just use the program to verify the digital signal is what it is and thats all. Not really interested in the data since it kind of boring to me. Maybe someone else can chime in.

cg · Feb 26, 2015

It has been a while but I recall that Flex C & D require hardware slicer. Things may have changed but I thought there was some that you still needed the box.

foxtail · Mar 2, 2015

That's what I thought. I use a real 4-level slicer on win 98 and Xp and see frames A, B, C, D. When I use the hackrf or rtl with vc software cable it only shows A, B. So it looks like your only getting half the decodes when using the sound card way and not the serial way.
