rtl-sdr

Hello all, I am running OP25 on a Pi 3B and sometimes OP25 bugs. I was able to catch that in the stderr file this is what I found: 09/23/23 17:23:10.515841 [0] releasing: tg(50003), freq(772.256250), slot(1), reason(duid15) 09/23/23 17:23:11.738840 [0] voice update: tg(50003), rid(0)...

Hi there, I am very new to the subject of SDR, so please be gentle! I'm based in the UK. I'm getting some work done to my roof, and in the next few days I have an opportunity to change/upgrade my TV aerial. I've been pondering a project for a wee while, to use a Raspberry Pi to tune into our...

Check out my RTL SDR pole i have in my office at work to listen to Mississippi MSWIN while im at work. I found a pole at home I had in some amazon portable photo studio in a bag that held a light. I have two omni antennas and one yagi antenna on this pole along with 2 RTL SDR dongles. I have a...

Is it possible to listen to multiple talkgroups with a single rtl-sdr or are you restricted to 1 talkgroup at a time. Could someone give me a little info on this please?

Thanks to a lot of people who helped me along the way, I have successfully restored the memory image to a damaged RDL-SDR device. Attached is a .PDF file showing the steps I followed. If the procedure is unclear, please suggest changes.

Greetings: First of all, I do not know if I should have placed this thread either in the "Antennas" thread or in the "SDR" thread. If I placed this in the wrong thread, I apologize. My logic was that I am specifically wanting to discuss those micro small SMA antenna connection points on the SDR...

In my last shack, I had everything in one Rack (Box) an 8U Black Woodgrain Rack (24"hx21w"x16"deep) which took up the whole left side of my corner desk, reducing my workspace. Great for the radios/scanners not good for desk space. In this new change, I found smaller narrow standard rack boxes...

Hello all. I've recently had time to get back into SDR after a few years and I'm having some issues with my new tuners and software. The SDR setup consists of a Windows 8.1 workstation with two tuners, the first a Nooelec NESDR v4 RTL-SDR (820T) and another NESDR XTR (E1000). The first time I...

I had an RTL-SDR.com V.3 dongle up and running on Windows 10. Then I installed a FlightAware Pro Stick plus dongle, it runs great! I can't seem to use them simultaneously though. I know they are both essentially rtl-sdr dongles on the inside. How do I run them both simultaneously? Is there a way...

Hi Everyone, Sorry for what feels like a dumb question. I have a (1) RTL-SDR connected to my MacBook (I have another spare SDR if needed). I am starting to use the SDRTrunk Software and hope to move my feed over to this software. My area's police department is on a single P25 frequency. I cannot...

I just got my sdr a few days ago and while scrolling through the spectrum i found some strange signals. It's a continuous transmission and it's not digital or at least not something dsd can decode. Does anyone know what this is?

Hi all, I've done a lot of searching to find any resolutions to a similar issue but am still having problems using Unitrunker and my two new RTL-SDR dongles (https://www.amazon.com/dp/B011HVUEME?psc=1&ref=ppx_yo2_dt_b_product_details) to run as both a Fixed and as a Scanner. While running this...

Hi there, I just entered the wonderful world of SDR and as such I am very new and inexperienced. I have watched a few videos online on how to decode P25 and similar trunked signals but these videos were fairly old. I have two RTL-SDR dongles (one RTL-SDR v3 and one NESDR Smart). I am using SDR#...

I'm having a hell of a time trying to set up my RTL-SDR V3 to decode my local police departments, each one functions on a P25 conventional single frequency. I've seen too many videos on Youtube and have read countless hours of forums and articles on how to set this up to absolutely no avail...

I am new to the SDR hobby. On the positive note, I am able to listen/decode Seattle King County/ValleyCom Simulcast (Motorola Type II SmartZone) in Auburn using UNITRUNKER software. When I switch to the SDRTRUNK, (in hopes of perhaps having more control over what talk groups I listen to) all I...

Hello all, I am looking for some help with SDR#. I am using a single dongle and would like to listen to my hotspot fusion conversations in SDR#. I have this working using FMP24 and DSDPlus Fastlane by itself but cannot seem to get it working in SDR# via the DSD Interface and or DSD+Ui...

I used to be into the old school Radio Shack Scanners, but a few years ago in my area, Idaho Falls, Id (Bonneville County) started encrypting their frequencies. I just recently found out RTL-SDR and purchased two of them to use with DSDPlus Fastlane. I can now hear agencies up to 60 miles away...

HI All I'm running into a huge problem that I've been trying to find a solution to for the entire day. If you don't feel like reading, this video describes my issues I just built a new computer to run some SDR projects. This PC was built for this and I think Murphy has his hands in this...

Nearly 5 years later, I've finally managed to carve out some time to add rtl-sdr support natively to dsd. Any feedback/testing/etc is welcomed. Usage: dsd -i rtl:0 -o pa:1 -c 446M https://github.com/szechyjs/dsd/pull/108
