sdr

I'm curious of it's possible to B-List individual radio's on a P25 system with OP25 Boatbod. A few members of a very special FD are just a bit much to listen to, so I want to block the UID's of their radios.

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...

Good day everyone. First off I would like to thank this excellent community for all the help they offer people. I would like to also thank all the open source developers in regards to SDR and GR. I have a question for the community and hopefully someone out there may have an answer. I have...

Hi all. Based in Gloucestershire, UK. Having spent the last few days looking around POCSAG and Flex, there seems to be only two frequencies that contain anything. Literally anything: 153.025 and 153.350. Although these frequencies are busy - everything that comes through on PDW is up north...

Trade-offs: price -vs- headache factor (SDR dongles -vs- a real scanner radio). There is a lot of talk about hooking up multiple SDR dongles into hubs, using multiple power supplies, gobs of cabling, antenna splitters, with software configuration nightmares, etc. So my question is, how many...

When I boot my laptop running Windows 10 and start an SDR application it's 50/50 chance the SDR device will start and communicate with the software with no issues. I have 4 different software packages, and 2 different SDR dongles. The behavior is the same on my laptop. 1. 4, Installed...

Selling seldom used Afedri LAN-IQ SDR. This is a very versatile standalone SDR that shows 768 KHz of spectrum as a standalone, and 2.2 MHz when connected to a LAN and accessed via SDR Console or HDSDR. Exceptionally sensitive on VHF and above. I never used it for HF reception. It covers 50 KHz...

As a SDR based feed provider for Broadcastify calls, I would find it very helpful to be able to fetch statistics from the Broadcastify database / API. Being able to know how often a node picks up a talkgroup and when can be very helpful to determine if other nodes nearby should also monitor that...

First of all, I am using SDR to monitor ICORRS here in Butler. Specifically op25 on a Raspberry Pi. I stream the audio via Darkice and Icecast. Importantly, I can view my Raspberry Pi display via VNC and see the real-time activity in op25, but my audio is ~1 minute delayed because of the...

I had PDW running perfectly stable for years, but recently it has started crashing after random periods of time (sometimes 10 minutes, sometimes an hour). Reports a BEX error every time. I'm running Windows 7 with an older version of SDR#, but also tried with the new SDR++ and the same is...

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...

I have access to the RAS key for a particular DMR Cap+ system that I would like to monitor using an SDR software. I am currently familiar with DSD+ and SDRTrunk programs. Is there any way to input the RAS key to be able to effectively decode and listen to this system in any of these two...

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?

Just purchased an ICOM IC-PCR100. Tried the Wiki, but broken links trying to get software to operate it. Was suggested to try and run PCRAnyWhere software, don't know if the unit is a dog or even works yet. First of all, assume I'll have to use a serial to USB adapter for Windows 7 or W8...

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...

I have 4 SDRs that i want to use on one antenna for 800MHz trunking. How can i properly figure out how many sdr dongles i can have connected to it before signal gets too low. Im getting a Nooelec LNA that has +20 Db of gain.

I bought a Raspberry Pi 4 (8 gig) to run SDRs on, and other stuff. I have 2 SDRs, a NoElec using an 820T chip, and a DVB with an 820T2. Have OP25 set up and working, but when I try the command line to get the NAC, I get several errors, starting with PLL not locked, and "value error, need more...

I would like to change my OP25 whitelist based on the time of day. I'm running a single instance of OP25 in terminal mode launched with the command line: ./rx.py --args 'rtl' -N 'LNA:47' -S 1000000 -o 25000 -T trunk.tsv -V -w -2 -U 2>stderr.2 --crypt-behavior 2 In the evenings, I change my...
