Is there anyway to enable bias t currently with the use of DSD+ fmp24? I saw some posts but they were a bit older and want to know if its an option now?

Hey all, was searching for an answer to my problem and finally solved it and wanted to share here for others having the same issue. (I've seen a few posts having the same issue but are very old, hopefully this helps someone out that has the same issue. ) I have 2 version 3 dongles from...

Hey, Thanks to boatbod's setup, OP25 is running nicely on an old laptop I had running Ubuntu 18.04. The only weird issue is that it seems like the SDR's noise floor's do not change significantly when messing with the -N 'LNA:xx' setting in OP25. The noise floor from what I have seen in GNU...

Hopefully, I'm posting this correctly? Is anyone familiar with what a "libfftw3f-3.dll" Error is?? I downloaded DSD+, DLL files & Fastlane onto my windows 10 laptop. Then I opened DSD+ & copied the files from DLL & Fastlane into the DSD+ file. Next, I edited my control channel frequency for my...

I know the city's P25 system is fairly new (and still seems to be underway), but I was hoping someone had some insight to its current status/functionality. I set up an SDR last week and programmed in the P25 system and was able to pick up fairly decent audio for a few days. All of a sudden, it...

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...

I have new Project need some advice, I like to set up a broadcastify stream, I have an Airspy R2 SDR our local police uses P25 Phase 1 trunk system they will be switching over to Phase 2 in June of this year, I'm looking for something where I could use a Raspberry PI with Sdrtrunk or OP25? like...

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...
