rtl-sdr

Hello! I've configured my RaspberryPi 3 with RTL-SDR according to this guide Raspberry Pi RTL-SDR Broadcastify - The RadioReference Wiki I have my own IceCast server. After I've launch transmission I received sound from IceCast with interruption. It is hard to explain, that's why I...

I have a new RTL-SDR R820T2 and it is acting weird with my Windows 7 computer. SDRSharp and HDSDR will run OK but then suddenly the program crashes and the window closes, but the program still shows as active in the task manager. When I try to start it again, or the other SDR program that one...

Hi, I have applied to be a feed provider. I plan on streaming OKWIN only here in Oklahoma City. I will not be streaming EDACS Provoice due to the nasal (holing your nose and talk) sound DSD Plus has on it. I tried many many different possible DSD Plus tuning values. Even tried the CPU load...

Greetings all, My university uses an unencrypted MOTOTRBO Capacity Plus radio system that I am trying to monitor/scan using a spare Windows 7 computer with a RTL-SDR unit, SDR#, and DSD+. As far as I can tell, my university's radio system has four frequencies across two channels (Channel 1: Rx...

Hello I just got a generic RTL-SDR the other day. I can't get it to install. When I plug it in to a USB port, it either doesn't see it, or I get the response "Windows doesn't recognize device due to malfunction". When I look in device manager, it read "Unknown USB Device (Device...

I'm wondering what the current lineup is for software choices for the RTL-SDR and NooElec Mini 2+. I've read through the posts I can find but a lot are from 2014 or even 2013. Looking for Windows 8.2 x64, free, and on the simple side for my first exposure to SDR. The posts appear to point to...

Hello there I’ve just gotten into sdrs and I need to get a USB hub. is there a certain type of hub I need so that I can get all of sdrs plugged in? Also I need some sort of antenna splitter so that I can use my outdoor antenna on all of the sdrs instead of the cheap antennas they give out. And...

Hi guys, So I was playing with a rtl sdr dongle lately and came across a strange signal exactly at 120 mhz. I am using gqrx for sdr side. Any idea what it is? Here is the gps info of my location if relevant: Latitude:31.70677465 N Longitude:76.52492523 E Sea level: 882 M

It has been found from a post at rtl sdr reddit channel that in certain cases removing the remote diode sensor in the RTL dongle receivers can reduce the amount of out of band interference. I have done this to mine. My personal findings is there is a marginal increase in reception using the HF...

For most experienced software edfined radio users already know what this is. For you that are brand new to the sdr hobby I have a short demo to show you on HDSDR's notch filter usage. Not really explaining it. RR people will explain it. this thread is basically a FYI thing. You can watch the...

Is there a way to use my RTL SDR dongles to feed a 'Radio Reference Feed'? Becoming a Feed Provider - The RadioReference Wiki I have 3 vhf radios and a PC that just had a catastrophic failure and It would be nice to downsize/optimize the setup. Something like ScannerCast but for SDR Dongles...

Hi Forum Geniuses, I'm hoping you can point me in the right direction, If recently got a RTL-SDR USB and I'm using SDR Sharp with it. I'm using it with a range of antenna's ... Homebrew Carolina Windom 80 at 20m, 10m/11m bobtail curtain at 10m and a tunable 2m dipole at roof height. I've...

Hi- I just received the ezcap RTL TV DVB-T USB dongle in the mail- direct from China. Total time from ordering online to my mailbox was less than 9 days. I installed HDSDR, got it going (took hours and hours of reading the instructions, settings, and figuring out why no sound coming out of my...

I'm brand new to radio, software defined or otherwise, so forgive me if this is a particularly stupid question. While listening with my RTL-SDR dongles, one E4000-based and the other an R820T, I can hear broadcast FM on 31.1. The station I hear on that frequency is 106.7, and both dongles pick...

So, I'm trying to calibrate my NooElec RTL-SDR RTL2832U & R820T for SDSharp, using the stock antenna, which actually gets pretty darned good reception. Problem is, upon calibrating my signal, so it sits center of the peak, I get this high pitch noise. If I readjust the signal so it sits a bit...

Hi folks. Just ordered an RTLSDR with the R820T tuner. Although I'd like to have some general fun with it (can be used for TRBO with DMRDecode can't it?) the main reason I got it is to create a feed for Plane Plotter. Got lots of questions, so open to suggestions from anyone who has done this...

I just put together a somewhat comprehensive howto on creating a Police/Fire/Medical radio scanner on instructables.com. It uses a single receiver and works pretty well for the price. Hope it can help anybody interested in putting one of these together! How to Make a $19 Police Radio Scanner
