rtlsdr

Hello everyone, I was wondering if anybody would know why sometimes when I'm using my 2 RTL-SDRs to listen to a P25 system it will pick up all transmissions, but then randomly it will miss one. Does anyone know how to fix this?

I noticed a few months back that one of my blue RTL SDRs (RTL2832U+R820T2) had died. I have a bunch of these dongles and you used to be able to get them for under $10. With a little bit of shielding in select locations (not shown in image) and the addition of a TCXO (at the time I did them...

See image below. For some reason my RTL-SDR has decided that it wants to be USB Device 0. I have no idea how to change that and Zadig does not see the USB radio (SDRSharp does see it) so I'm guessing it's stuck on Device 0. The big problem here is FMP will not accept Input Device 0 (-i0)...

Hey everyone! I figured out how to listen to the Motorola Type-II trunking system using a couple of RTL-SDR USB dongles and Unitrunker. Even though the Motorola Type-II network will be retired by the end of this year, I thought some of you might appreciate this walkthrough in the mean time...

I've recently gotten an RTL-SDR v3 dongle and have been trying to listen around and had a few questions. Getting right to the point, I'm trying to use SDR-Trunk to listen to UCA but I'm unable to get any data from the control channels an I don't quite know why. To my knowledge I should have...

Hello Everyone, I have setup Broadcastify Calls using a RTLSDR dongle, Trunking Recorder v3.1.4790.7807, Unitrunker v2.1.0.58 VB Cable A & B. All is working as it should. However I am scanning a system on only 1 site and it’s busy. For example, I would like to capture as many streams as I...

Hey peeps! I've recently bought a RTLSDR dongle, RTL2832U. I've followed the set-up of both this, VBAudiocable and PDW. I've put my settings to the following, (see file attached). Also included is PDW signal and what's coming out. I can't seem to get over 20% which is very sad since I...

I am looking for a linux based Motorola Smart Zone II decoder compatible to RTL-SDR dongles. I have 3 of them. I tried SDRTrunk but it won't do it. I can't run a virtual box it'll be top much on my laptop. Windows has a few but anything that looks like a 'penguin', or linux, doesn't have one but...

I've got OP25 (boatbod) rx.py working using an RTLSDR dongle, and the audio sounds great. Is there a way to simultaneously receive/decode more than one channel that falls within the RTL's 2.4MHz of spectrum being sampled? The two channels I'm interested in are not trunked channels. They were...

Hey everyone, I want to listen to a trunked system, ICIS https://www.radioreference.com/apps/db/?sid=2856 I have two RTL-SDR's connected, and they both work in SDR#. I'm trying to listen to Montebello's systems, I have Unitrunker's Signal on the primary control channel, and Voice (from my...

Hello RadioReference! I'm using an RTL dongle to listen to LASD frequencies in my area, and I'm confused about a few things. 1. I understand the busy tone, but why is it sometimes a steady pulse of beeps and other times it sounds like morse code? 2. With SDR# I get a waterfall view of about...

Which programs supports spyverter, and where you get them... and setup instructions?

Hello! I'm a bit of a newbie here and with SDR in general, but I had a question about RTL-SDR dongles. From what I've heard and read so far, RTL-SDR dongles are the cheapest way of getting into SDR while still having a fairly quality product. I impulse-bought a dongle a few months ago when I...

Hello, I've finally got Unitrunker up and running with a FunCube and RTL + SDR#, it's great however there's one particular system that I track that gets a TON of activity (Detroit City Simulcast) and so the scanner goes a bit wild switching from one group to the other, sometimes cutting off in...
