Got a usb rtl sdr. Used sdr# and virtual audio cable piped to dsd plus..it was working years ago. Now dsd just shows the nac, all audio is garbled.tried changing the levels in sdr, vac, windows audio control panel. Strong signals. Filter audio in sdr# is unchecked and frequency correction is...

@GTR8000 was giving me some info in another thread but we got off topic. I'm working on getting SDRTrunk setup to handle BCFY Calls for my county, but want to ensure I have the necessary configuration. I was informed I'll need a total of 3 SDRs to handle all the frequencies, but my question is...

I cannot seem to get the setup I have working correctly. I have a maxtrac 800 (yes, it is receive only before someone brings it up) line input that works absolutely wonderful and has for a couple of years. I want it to be the channel control for a single SDR being the voice channel. I cannot get...

Hi all, I’m wondering if anyone could help me, I’m ,running SDR# with the fast scanner plugin. I want to know if it is possible to output the active channel frequency name into metadata so radio feed (ProScan) can read this metadata and show it on the audio feed? Thanks in advance.

Hello, I have recently been looking into and researching SDRs and I was wondering if it is possible to use a SDR to discover new P25 trunked radio systems and talkgroups? If this is possible what software should I use? Thanks in advance, Brad

I have a RTL2832U sdr dongle and everything was working fine, but I was encountering a strange error in logs of some programs on both windows and linux using the librtlsdr driver (an older branch with IR support). I narrowed it down to my USB 3.1 port causing it. My solution was to just move it...

This SDR had a reasonably brief stay here. I am the original owner. It is in excellent condition and was always used indoors in a non-smoking environment. Includes original box. This does NOT include a USB cable; SDRPlay did not include them. You must provide a standard good quality USB cable...

Hi Team. Looking for your suggestions on how to accomplish something, if it is even possible! I would like to run a Pi at my cousin's house where the reception is much better than at mine. With 3 or 4 SDRs installed on the Pi (could be a mix of Airspy units, RTL-SDR v3),I would want to be...

I love to experiment with different forms of communication attempting to capture the State of Colorado DTRS Simulcast system in my area. I am now ready to pass this SDR unit to the next radio enthusiast. Below is the description from the company. Asking $49 plus $10 USPS Priority Mail...

Which SDR Windows application do you guys use and the pros and cons of it.

Hi All! I'm having the same issue as this thread: OP25 Audio Slow and Choppy I'm using a brand new RPI 4b (1gig) and new NooElec NESDR smart v4 running raspbian buster. I am trying to listen to the North Fulton Regional Radio System (NFRRSA). My first setup had audio that sounded terrible, so...

A friend of mine wants to set up a stream in his state, he has ordered 2 SDR's an antenna, and a Pi. He wants to use the VIPER on High Peak. Could anyone please advise anything we need to be aware of? And could someone maybe share a config for trunk recorder? Thank you.

Hi everyone, As I wasn't able to find anything on the topic, but think that this can't be my original idea and thus probably is implemented somewhere, I wanted to ask if anyone can give me a hint. I'm looking for a software to work with any SDR (but ideally RTL-SDR devices) which can integrate...

Is there anyway to enable bias t currently with the use of DSD+ fmp24? I saw some posts but they were a bit older and want to know if its an option now?

Hey all, was searching for an answer to my problem and finally solved it and wanted to share here for others having the same issue. (I've seen a few posts having the same issue but are very old, hopefully this helps someone out that has the same issue. ) I have 2 version 3 dongles from...

Hey, Thanks to boatbod's setup, OP25 is running nicely on an old laptop I had running Ubuntu 18.04. The only weird issue is that it seems like the SDR's noise floor's do not change significantly when messing with the -N 'LNA:xx' setting in OP25. The noise floor from what I have seen in GNU...

Hopefully, I'm posting this correctly? Is anyone familiar with what a "libfftw3f-3.dll" Error is?? I downloaded DSD+, DLL files & Fastlane onto my windows 10 laptop. Then I opened DSD+ & copied the files from DLL & Fastlane into the DSD+ file. Next, I edited my control channel frequency for my...

I know the city's P25 system is fairly new (and still seems to be underway), but I was hoping someone had some insight to its current status/functionality. I set up an SDR last week and programmed in the P25 system and was able to pick up fairly decent audio for a few days. All of a sudden, it...
