This long weekend I wanted to experiment with my Airspy Mini SDR and some software called rdio-scanner.
rdio-scanner creates a customizable web interface from which to control your software defined radio. Using it, you can turn a computer, phone or tablet into something that closely resembles a hardware scanner!
Trunk Recorder is the software that decodes the unencrypted P25 signals and records them to disk. Here is it demonstrated working on a large Simulcast (LSM) site.
rdio-scanner reads the audio files. Through the rdio-scanner interface, you are basically choosing which audio files to play.
Have a look at the video, and comment below if you use Trunk Recorder or rdio-scanner with your SDR. Or tell me about your solution!
**You don't need an Airspy product, all this software will also work with the infamous RTL-SDR v3 and NooElec SMART dongles as well :-) **

Really enjoy your videos! Would you be able to do a step by step video on how you are able to listen to the P25 AFRRCS in the Edmonton area? I am also located in Edmonton and would like to listen to the area with a RTL-SDR dongle?

@EverydayJ1786 Год назад

Rob, Jordon here . Very cool insight to a new piece of software that I'll have to try . I'm currently in the process of moving back into Edmonton. Can't wait to get setup and start monitoring AFRRCS again with DSDPLUS .... I also acquired a brand new 100 ft. spool of 14 gauge wire . I Plan on making some kind of HF recieve antenna to connect to my noolec balun one nine . Lots of fun stuff in the works ! . Take care

@FrugalRadio Год назад

Great to hear from you again Jordan! Sounds like you've got good plans for getting the new place set up. Best of luck with the move!

@asaffeig4343 Год назад

I've been using Rdio-Scanner with SDR-Trunk for a couple of months now, also using Rdio-Scanner app on my Android phone so i basicly turned my phone into a scanner, great app.

@FrugalRadio Год назад

Great to hear. I had considered using SDR Trunk instead of Trunk Recorder. I may switch over to it instead for my next experiment. Glad to hear it works well for you, thanks for letting us know!

@KngChrisTv Год назад

How do i setup it up?

@FrugalRadio Год назад

With a bit of trial and error, and a good read through the documentation! I'm certainly no expert, but managed to get it going. I am going to try setting it up with SDRTrunk next time. I used the Docker container available at rdio-scanner, on top of the Dragon OS Focal Linux distro designed for SDR enthusiasts.

welcome back my friend ,Tim

@FrugalRadio Год назад

Thanks!

@colonelangus75 Год назад

I use SDR# with the simple APCO plugin and the Frequency Scanner plugin so that I can listen to both P25 and analog transmissions. It's not the most ideal setup, but it's the easiest way I've found so far to listen to both analog and digital transmissions.

@FrugalRadio Год назад

Great, thanks for filling us in. That sounds like a fast way to get up and running. Would work well for P25 conventional I imagine!

@colonelangus75 Год назад

@@FrugalRadio It should work with conventional P25 as well. One of the main drawbacks with doing it this way though is you can't lockout an unwanted talk group or encrypted transmissions.

@FrugalRadio Год назад

Yes, I can imagine that could get frustrating. Especially if it was a busy system.

@briantooze3415 Год назад

Hi, I am just getting into this hobby and I enjoy watching your videos. Please could you consider doing a video on upconverters. Are they worth purchasing for an existing SDR system or is it best to go for the HF+ Discovery? My current setup is on a Raspberry Pi so any "frugal" tips for the Pi would also be appreciated.

@FrugalRadio Год назад

I'll give that some thought Brian, certainly. Thanks for following along with the videos.

@Mariko_Switch Год назад

I use trunk recorder as and kinda do the same thing that you are showing but instead I have a calls platform on broadcastify not the regular broadcast and gives me a web interface that I can access anywhere I have internet and the calls platform will document all takgrups and also gives you access to all your calls

@FrugalRadio Год назад

Good to hear about another way of accomplishing the same goal. Have you got a web address that gives details of the calls platform?

@jameswhitaker1324 Год назад

I use two rtl-sdr radios, dsp plus and unitrunker to monitor the local p25 Motorola smartzone system locally., not mobile, just at home.

@FrugalRadio Год назад

Thanks for your comment James. Are you using both Unitrunker and Dsdplus for audio? Monitoring different agencies on the same system, or different systems?

@jameswhitaker1324 Год назад

@@FrugalRadio Pretty sure the DSP+ is just there for the control channel. The P25 system has a few thousand talkgroups, but I mostly just monitor my local PD. Sometimes I'll listen to other talkgroups, too, depending on what's going on.

@FrugalRadio Год назад

Yeah, some of these systems have a lot of talkgroups! It's really important to be able to pick & choose which we listen to. Things get far too crazy if you end up hearing everything!

@unhinged17 Год назад

I own a 3 year old Airspy HF+ Dual Port SDR that I am having a devil of a time getting up and running well. All the tech support and attention has gone to the newer HF+ Discovery, hardly any support information is available anymore for the once "lauded" HF+ Dual Port. Do you have any advice? I have a Youloop antenna I'd like to use with it but for the life of me I cannot figure out how to do the R3 surface mount mod inside the bloody thing without the risk of breaking/bricking it. Do you ever do one-on-one sessions that can help me figure this out please? I have a Nooelec NESDR Smart and an RTL-SDR dongle that far outperforms my Airspy, so what gives?

@FrugalRadio Год назад

Hi Jason. Sorry to hear about the problems you've been experiencing. I wouldn't be keen on removing a surface mount component myself either. I've never owned that version, so I would recommend joining the AirSpy group.io page. Some of the users in the group have that version and I'm sure would be very happy to assist.

@briangutierrez7404 3 месяца назад

Is there any way to add new frequencies to Rdio Scanner? Just got it for my county but they don't have most towns. Any tips?

@FrugalRadio 3 месяца назад

Rdio-scanner only plays what you have already recorded from somewhere else. To add frequencies you would need to use your SDR & recording software.

@briangutierrez7404 3 месяца назад

What antenna are you using?@@FrugalRadio

@FrugalRadio 3 месяца назад

I use different antennas based on the band in listening to. This was probably done on a 700 MHz dipole, but could have been a Larson 150/450/ 758 tri band mobile antenna as I have a couple of those as well.

@KngChrisTv Год назад

Are you going to make a setup of Rdio-scanner videos?

@FrugalRadio Год назад

I'm not planning to at the moment. This project was a proof of concept test, but I don't have time to implement it just yet. If I decide to pursue it for a set up, then I might make it into a video.

@KngChrisTv Год назад

@@FrugalRadio Ok. I have a question, do you know any antenna that can I use for SDR and radio/scanner altogether, like a wide band I think?

@FrugalRadio Год назад

There are 2 routes you can go. 1 - use a wideband discone for general coverage such as amzn.to/3jNPHx0 2 - make or buy an antenna for the band you listen to most, and accept the lower performance on other bands.

@KngChrisTv Год назад

@@FrugalRadio How do I use SDR Trunking /Trunking Recorder with Rdio Scanner?

@FrugalRadio Год назад

You set up a folder for trunk recorder to drop the audio files. Then you tell rdio-scanner what folder to monitor.

@attribute-4677 2 месяца назад

What is the latency for Rdio to play the call after it ends?

@FrugalRadio 2 месяца назад

I didn't measure the time, but I found the latency to be higher than I would prefer. An entire transmission has to be completed before the message plays back. It is quite noticing when there are long transmissions, especially if you have another SDR or scanner that is monitoring the frequency / transmission live.

I haven't heard of it. Feel free to post a link here. If it relates to an antenna for receiving TV signals specifically, then probably not. If it is an antenna for receiving utility signals in VHF / UHF / Satellite bands, then I might be interested based on how it might benefit viewers of the channel.

@windvane_npk5844 Год назад

Why do you need a data card, you can’t use this set up “off grid”?

@FrugalRadio Год назад

If you are just running it on a PC, like the Toughbook in Tablet mode, then you can run it all on the one computer. This would allow you to do it off grid. It would necessitate using other software though, such as SDRTrunk as the recording platform. This would need a more powerful PC.
