For everyone seeing this video now. This was posted 5 years ago. If I were to make a walk through type video again, I would put more effort into it and do a better job. I know some people like this video and some people don't for different reasons. I'm ok with the constructive criticism for it will help me make better videos on the future. I know there have been quite a few questions asked here. Some I have answered and some I haven't been able to answer. Since this video, I got a digital scanner and haven't played with an SDR or anything like this for a while. I am very happy with the amount of comments and views on this video.

@andygorman3123 2 года назад

I would suggest breaking it into 2 or 3 videos. One on choosing equipment. Second on setting everything up. Third on getting the software and equipment working and how to start decoding a system. Good work!

@WesPsWorld 6 лет назад

Thank you for this video. You explained it better then anyone I’ve seen. I subscribed to your channel. THANK YOU again!!!!

@larrygall5831 4 года назад

"Un-check listen to this device.." Best advice I've got. I watched a few of these videos, and none said this. I was getting staticy calls that were near impossible to hear through, and was going nuts trying to figure it out. I was using Unitrunker and kept changing settings with no luck. _This_ was what fixed it.. my box was checked.

If I were to make a walk through video like this again, I would put more effort into it and do a better job. This was 5 years ago and I was newer with RU-vid videos at the time. I'm ok with constructive criticism.

@stevenA44 2 года назад

I just want to say (for now) that even though you kind of stepped back and forth through this, it sounds like the easiest setup I have found. That being said, if this actually works and I am able to hear the state police that is on P25 in my area, I will come back here and like the video.

@JaredPaxton 2 года назад

Thanks so much for taking the time to walk through this, but I'm still a bit confused. At 13:00 you show the Playback menu in Sounds, with Speaker/Headphone set to default (and VB Cable Input NOT selected as default). You also say, "make sure the speaker you want is selected as default for playback." However, at 16:23 you show VB Cable Input marked as default in the Playback options. Which is it supposed to be?

@w9x7cv3vg6 6 лет назад

This is a very neet video and thanks..good way to go into the next step after getting sir sharp going..but my next step is to jump right to trunked p25 and of course I know the ops frequencies on the local tower other than the data control freq.,but I wonder if I can use this with some kind of trunking control software to monitor the control freq.then of course we have talk groups in there...a little fancier than just monitoring one freq like your doing down there.our p25 stuff is in the 700s and yes I have long range uhf antennas as I just sold my 996xt to a local for his listening pleasure as he is not into high tech stuff like this..thanks have a nice day...

@pclever1 5 лет назад

Hey, I have been trying to get DSD+ to work on my system for a few weeks now with little progress being made. I am using an RTL-SDR and I have everything set up like you did but DSD+ is not able to output any audio. I can see that it is decoding P25 phase 1 data with a good signal strength but it isn't working properly on any frequency I try. Can you give me some advice on what to try next? Thanks!!

Hi like the vid , But can you tell me what folder did you place the VBABLE_DRIVER_PACK43

@n1kkri Год назад

Are there any inexpensive 800MHz beam antennas with pretty good gain. I don't get a strong enough signal to give me good P25. Breaks ups with garbled audio. I am thinking about using a UHF TV antenna mounted vertical unless I can find or build something cheaper. I verified my setup works by driving closer to the P25 transmitting antenna giving me a much stronger signal and I had pretty good audio.

@JaredPaxton Год назад

There are plenty of antenna options on the DX Engineering website.

Install SDR#, place DSDplus files into SDR# folder, install the DSD plugin into the SDR# folder, Install Virtual-Audio cable, then from there you can access DSDplus and adjust your settings, like the bandwidth 12,500, etc.

Audio settings in DSD audio input device #1 (CABLE Output (2- VB-Audio Virtu) initialized audio output device #2 (Speakers (2- AudioBox USB Audio) initialized I also can't set output as anything else, I have set VN cable output as Hyper X headphones SDR# output is [windows direct sound] Speakers (2-VB audio cable)

@phillipwilhelm 3 года назад

can you use sdr# to scan trunked and non-trunked at the same time?

@donmccubbin1740 7 лет назад

Jarred, Thanks for the video. Just wondering how SDR# is setup to use 2 RTL-SDRs with DSD+ to copy P25 (phase 1) the control channel and to also scan the voice channels. The network I listen to has 16 voice channels from 854 to 861 MHz. After watching the video, I see the CC info scrolling but How do I get the 2nd RTL-SRD copying the 16 voice channels? Regards, Don

@Mel0763 5 лет назад

I use Unitrunker version 1 to handle the control channel and voice receiving, then pipe the audio out to DSD+. Unitrunker handles all the trunking aspects. In fact, version 2 of Unitrunker, which is very much still in beta, doesn't even need DSD+ to decode P25 phase 1. It does it all on it's own.

@omw9965 4 года назад

What's the difference between P25 and P25E? I followed the steps and receive some encrypted Fire Dept Radios but one that says P25E was hearing at first but then could not hear again, the only thing I noticed is that the DSD+ message box displays a message after Sync: P25p1 NAC:501 TDU (Muting Encrypted Voice) but I cannot hear no decoded voice.

@garyhopkins7260 4 года назад

I've come across several of these videos yours is encompassing quite a large amount which I did not find in other videos that had five parts to them although what I am suspicious of is that do you need to run unit trunker with this and do you need to SDR dongles I am utilizing mine on the Connecticut State Police to monitor and as others have quoted I do not get any audio now I've gone back several times to recheck my configurations and I do have what you suggested any input would be greatly appreciated

@JaredPaxton 4 года назад

You only need 1 SDR for P25 Phase 1 conventional. P25 Phase 1 or 2 Trunking you need 2 SDR. There may be updated versions of software or files at thise point.

"Mono audio decoding initiated; press ESC to exit..." How do I get this setup running?
