Hello, I am receiving the attached error messages while running SDR to monitor a P-25 system using Windows PC. Does anyone know what it means? The decoding is still working as far as I can tell. Thank you

Wondering if I should buy a Samsung Galaxy A7 tablet to run SDR++? Thanks.

Hey Guys, I was wondering if someone could assist me with removing this talk group with the “P” as it is irrelevant and I do not want it being scanned. Any help would be appreciated. Thanks!

I recently built a mobile radio scanner to monitor P25 trunk communication systems based on OP25 (Boatbod). I have been working on the project for 3 years and am finally happy to say that it's done! I am using a NooElec SMArt v3 dongle as hardware, Raspberry Pi 3B for signal processing, 3.5"...

Greetings: First of all, I do not know if I should have placed this thread either in the "Antennas" thread or in the "SDR" thread. If I placed this in the wrong thread, I apologize. My logic was that I am specifically wanting to discuss those micro small SMA antenna connection points on the SDR...

RTL2832U R860 V.3 SDR# V.1.0.0.1872 I have downloaded both the CTCSS and DCS decoders, placed the .dll file in the SDR# Folder, and written the code into the .xml document, but neither one will work to decode. Any thoughts on how to get these working?

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...

Selling my RSP1a. It's basically brand new, but I decided to get an Airplay HF+ instead since I'm most interested in SW listening. Asking $90 shipped. Shoot me a message if interested. Thanks for looking!

Hi at all, I have now tried Openear 1.7.0 on two PCs (one with WIN 7 in the final version, one with Win 10 incl. all updates) on neither PC is it possible to start Openear. It seems that MSVCR.dll files are always missing. First it was the MSVCR100.dll, after I installed it Openear did not...

A question in the round and to the SDR experts. I am new in the matter of SDR reception (with an Airspy mini and SDR#) and I am looking for a Plug-In to make the SDS readable at the Tetrafunk. Is there such a Plug-In for SDR# ? Gladly also another which runs under Windows. Many thanks and...

Great condition Airspy R2 for SDR scanning. Everything works great, including the original USB connector. View more info here: Airspy R2 SDR – Airspy.US

when i try to hear a radio or a frequency like 93.5 or any other and i go to shortwave for example the 93.5 radio is in shortwave (see picture) and the frequency changes when i go "up" in the frequency, and when i go above 200mhz appear like in the screenshot at 416mhz, the antenna can be near...

****SOLD**** Good morning, I've decided to sell this receiver as I feel that I am considerably under-utilizing it and I have some ideas for other projects that might suit my radio room better. I purchased it from HRO in Salem NH on 4/19/21 (.jpg of receipt is attached). Here is HRO's info page...

**SOLD** Great portable SDR. Requires external 5VDC power supply (not included). Also requires speaker (not included). This will display 768 KHz of bandwidth in portable mode and about 2 MHz when connected via LAN. Exceptional receive capability from "DC to Daylight". Includes USB power...

**This sold at QRZ** This is the real one, not one of the Chinese knock-offs. I received it about 6 months ago but I'm just not using it. If you try to buy one new they take a great deal of time to arrive, and in the current world situation, who knows at all. This one can be yours if you're...

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...
