Hey everyone, I want to share a project I’ve been building for the community called GopherTrunk (GopherTrunk.org). It is a software-defined-radio scanner designed to follow digital trunked-radio voice calls and decode them directly to audio. I wanted to create something incredibly easy to...

I cannot for the life of me seem to decode POCSAG via PDW with my RTL-SDR or RSP1A. I have POCSAG 1200 baud on 152.480MHz, but I cannot get it to decode. I can't even get PDW to detect that I am attempting to decode POCSAG. I have the VB Virtual Audio Cables installed since I already use...

Hey everyone, I’ve been playing with SDR and programming for about 5 or 6 years now. Like most of you, I’ve navigated the "pain in the ass" process of getting OP25 and Trunk-Recorder running. I’ve become pretty good at manual setups over the years, but for some reason, getting Trunk-Recorder to...

Hi, today I've been trying to install the new version of DSD+ but I'm having problems. I have the "TCP Server" plugin in AirSpy on port 20001 and DSD on the same port, but I'm getting this error. The error keeps repeating in a loop. I've searched for more information online and on chatgpt, but...

Hi all, I've been working on my SDR wall for a few years now and have been working on scanning for things that are a little bit of everything. Using a few diamond discone's in the attic, an LNA and FM block - through to a 16 port antenna splitter/combiner from MiniCircuits I am able to grab an...

Here is a description of all of the features. Mlite-880

I am trying to listen to mass state police with SDRTrunk on osx. I live in essex county. I am using the radio reference connection to create the channels but can not get anything to play audio. Has anyone successfully used SDRTrunk to scan the mass state police? Here's what I am doing 1)...

Hi there! niliBOX is software to handle some type of receivers, including SDR dongles and SDRplay RSP1A receivers. I have recently released the version 1.2.0. It comes with many new functionalities, while keeping the simplicity of older versions. - Works on Windows, Linux, macOS, Android and...

Wondering if anyone has any experience building SDR's by gathering components and integrating them. My main components list so far: Raspberry Pi 5 (4 GB) Elecrow 5 inch touchscreen RTL-SDR v4 I was planning to use scanner antenna via the SMA port. Software stack is OP25/boatbod running on...

The used youloop I picked up has a damaged SMA connector on one of the loop branches and the feed line. Can I just shorten the bad branch, reterminate it and then repeat on the other branch to match the shortened length? How closely do the lengths have to match? I'm assuming I can just shorten...

I have an RTL-SDR Blog v4 currently and want to listen to 40m (particularily 7200KHz). A listing near me has popped up for an AirSpy HF+ and YouLoop antenna and I'm considering getting it. I only have the dipole kit from RTL-SDR blog and I know that's not good for HF, but I'm wondering if I...

I’ve been programming a mobile client for the KiwiSDR protocol, and I finally have something worth sharing: QiwiQ. It’s a dark-theme, portrait-mode KiwiSDR app for Android. Instead of running in the browser, my app processes the KiwiSDR stream locally on your phone. With no official KiwiSDR...

I am trying to get my SDRPlay RSP1B to demod/listen to P25. Bonus points for tracking in real time. I have all the operating systems. My native OS is MacOS, running 128G of RAM. ARM64 arch. But I also have Windows11, and Ubuntu Linux, running via Parallels. Any quick paths to success...

I’m in the process of researching moving my feeds from simple scanners to using SDRs. I know 8 is likely overkill but I have a 8 port multi coupler so I figured why not fill them with SDRs considering they are cheap. Everything will be mostly analog, with some P25 conventional (all public safety...

Just wanted to share my SDR / WiFi / BTLE Monitoring wall with some Amateur Radio PSK Reporter. P25 Control Channel Monitoring / Scanning Trunk Recorder SDR 315/433/915 Mhz for devices that sit in that range Kismet Wireless BTLE Beacons/Probes Monitoring Kismet Wireless RasPi's running...

Sorry for the vague title. I want to get into shortwave radio, but I am not sure where to start really. I found my interest in it through North Korea, they have a broadcast called Voice of Korea as most of you might know, and that's how I found out about shortwave. Had no idea this medium...

Hello all! I am looking for someone in the Austin area who's familiar with setting up SDR Dongles to receive / decode P25 Phase I/II data/signals in SDRTRunk or one of those. I've done it in the past but it was several years ago, and I just don't seem to have the ability to wrap my head around...

I have been running my sdr box on a 4th gen Intel i5 and found a Dell R360 for sale $50. Specs are 2X Xeon E5-2620 v3 cpus, 65 gigs of ram also had 2 Broadcom Quad port nics and a LSI sas card. One broadcom card was removed as well as the LSI card. It has 8 2.5 inch slots of which only one is in...

Well, I hope the title caught you :) I am currently working on my diploma project in Visual Communication and Programming and I need YOUR help! My goal is to create a platform/framework for signal data visualization (and interaction). In simpler words, it's like thermal/x-ray vision but for...

can someone tell me will this amplifer let me listen to vhf and uhf frequencies by amplifying them. Channel, Cascaded Ultra-Low Noise Amplifier
