sdr

Pretty much the title says it all , how would one go about scanning when there’s no scanning community that shares findings? Ill walk you through the spectrum and my setup here and if you can chime in on how people managed before RR database existed i would be grateful. Aside from the scattered...

Hi everyone, First post here and I don't know a ton about radios, especially in regards to SDR and digital radio. Long story short, I have an SDR dongle. I am using DSD+ and SDRSharp. I can receive and hear FM stations with it, and I can hear the 'static' of non-decoded radio frequencies, but...

I am beating my head on the wall trying to get PDW to work with SDR#. I have attached some pics of the setup with hopes someone can pick out what my issues is/are. I am using RTL-SDR and VB cable. Any suggestions will be greatly appreciated!

I have bought DSD+ Fastlane about 7 months ago and used it for a few weeks and forgot about it until, well today. I was scrolling through my email until I found the email containing my DSD+ Fastlane files. See, I went to the first email I got from them which told me to go to the next email they...

I’m looking for the buffalo police p25 frequencies to program my SDR dongles. Any help appreciated!

I am a long time member of radio reference and a long time scanner user who has recently begun a dive into software defined radios (6 months or so). And I have recently purchased a number a of SDRs (RTL-SDR, AIRSPY HF+ Discovery, and AIRSPY R2 w/ Spyverter). And during this dive with the...

I’m looking at getting a SDR to replace my scanner feed to Broadcastify. I have a few questions: 1) can I just “plug and play”? -if I plug it in will RadioFeed or other software that provides feed to Broadcastify recognize it? 2) playing off the question above, if not what do I need to do to...

Hello! Pretty new to radio, so forgive me if I mix up some terms. I'm interested in tuning into transmissions directly from NYPD mobile units, rather than repeater-broadcast frequencies featuring the dispatcher. I was reading this thread, which states the mobile units use a separate "talk-in"...

I have tried on multiple systems MacOS 10.15 and 10.13 as well as Ubunto 16.04 and it fails every time although i have followed the instructions from the Git Page... has anyone gotten this to work? if so, what are you using and what did you do? Any help is greatly appreciated.

Selling Airspy HF+ , has been indoors since purchased, I am the original owner. For detailed information on its capabilities visit Airspy HF+ (Dual Port) SDR – Airspy.US . This is an inexpensive but superbly performing SDR that works wonders on the HF bands. It works with its "native" software...

Hello SDR fans, I am very new to SDR.. I am planning to buy a RTL-SDR Blog V3 on amazon. It has shortwave HF support. I read somewhere you need to configure SDR's for shortwave to work properly. What values do I need to add or modify and where to put them in the GQRX software? I appreciate...

Airspy & Spyverter combo w/ included accessories. Purchased April, 2016 from AIRSPY.US. PCB silkscreen dated 16 Aug. 2015 and I don’t believe it is the current hardware revision. Firmware was keep current with GitHub (v1.0.0 rc10). Works well with SDR#1700. Several months later I purchased a...

As of today (June 28, 2019), I am finding that most local municipalities have moved to AFRN. On the old JeffCo Pub Services P25 system, I have no problem with my set up. I usually monitor 855.6875 for the control channel in unitrunker, and I route the output from to DSD+ for decoding the audio...

Just started to really get into SDR over the past couple of weeks and wanted to try to monitor local railroads to see how SDR compared to my traditional setup of a Kenwood TK-780 with a 160mhz tuned 3db gain antenna. I attached an identical antenna up to an RTL-SDR stick with the intent of using...

Hi, This is my first post on this form. I'm trying to get back into SDRs again but SDRTrunk is kicking my butt. I need some help building the JMBE.jar file. I'm following these instructions DSheirer/jmbe but every time I run the build command I get this: BUILD FAILED in 44s 5 actionable...

I thought this video was pretty interesting because it shows the many way SDR can be utilized. I am planning to experiment in SDR in near future and have not yet decided the HW platform. So I am just throwing this out.

I'm looking to get back into scanning, I currently live in the Chicago Uptown area and was wondering what kind of equipment I might need. I would like to listen to Police/Fire as well as Marine and Air. I'm currently using SDR for police but having a hard time figuring out fire and air and was...

I recently purchased a RD-5R and can program DMR no problem, but some of the frequencies I can receive in DSD Plus are TDMA. I can receive them fine on DSD, but then I program the frequencies, Color Code and Talk groups. I can't pick up any of there chatter, I have retraced my steps to make sure...

Hello all, I'm new here and to SDR in general so I apologize in advance for any mistakes or incorrect terminology. I was wondering if anyone knows of any software other than SDR Angel that has transmit capability for the HackRF One. SDR Angel works, although it's rare and very inconsistent...
