SDRplay Limited is announcing the launch of a new Software Defined Radio receiver product – the RSP1B. The RSP1B is an enhanced version of the popular RSP1A powerful wideband full featured 14-bit SDR which covers the RF spectrum from 1kHz to 2GHz. The RSP1B comes in a rugged black painted steel...

So I currently have 2 SDRs that I use to monitor my local P25 system via SDRTrunk. There is someone who already broadcasts the system to OpenMHZ and Broadcastify, and if for some reason they ever take their feed offline I would like to take over for them. I am trying to find a good way I would...

New to this whole SDR thing, bought something off of ebay called a Skyfall SDR. It has 2 of the newer (v3's), not newest RTL's in it supposedly. I can pick up the hum and noise of the control channel. Stumped on how to do the decode, looking to see if anyone knows how to finish setting up Sharp...

hey everyone my first post on this site so forgive me if its in the wrong place! i have a question/problem with DSD+, with the Output level as shown on the 'DSD Interface' plugin. I cannot get this volume level into the green .it constantly stays red and never goes green no matter how much i...

Hello, I'm a new user. I've previously owned an analog scanner and used it to listen to emergency channels before they went encrypted many years back. I decided to get back into it and ordered the Noelec RTL-SDR v5 from Amazon. I understand you ideally need two for trunking, but I wanted to see...

I just hooked up my sdr and I imported from rr my county, however after listening for several hours I noticed nobody is talking. I played around with it earlier changing the control freq and I was picking up neighboring counties traffic. I will post a few screenshots as well. I know my city is...

Hello community, nice to be here. I recently came in the radio world, i find it beautiful to play around. I have a RTL SDR V3 and started playing around with SDR# checking for signals in my arera. I found a DMR signal, always transmiting day and night non stop. Tried DSD+ on it and it says TIII...

I am trying to make it possible to listen to my rdio server outside of my home WiFi. I used tailscale and it worked fine, but I'd like to be able to share it with others without having to have them install tailscale. So I tried the port forwarding. I entered the internal port as 3000...

Hi, I have multiple scanners and dongles running all at the same time, and I've noticed something weird that's been happening lately. I have an analog only scanner that scans the airband frequencies from the nearby airport. One of those frequencies is the guard frequency, 121.500 AM. I have...

Hello, I feed to BCFY feeds, 2 calls nodes, and 2 rdio scanner servers. All of a sudden, and since the lost recent update, everything but the calls node's work. Once a call goes in line for either, it immeidaltey switches from "connected" to "temporary broadcast error) and no calls go through...

I just purchased a RTL SDR v3 upon inserting it into my PC yesterday & setting it to the dongle in the device settings it will not pick up anything what so ever. I am however using a wide range baofeng antenna which is pretty wide range (JUST TO TEST WITH). I was wondering if someone could could...

Searching for FMP24 or any leads for download. Thanks,

Hello, i set up a local rdio scanner server thats connected to sdrtrunk so i can roll the tapes back if need be. ive been editing the talkgroups and organizing everything, and have made some serious progress. however i am having an issue that just popped up out of nowhere. all of a sudden, when...

I'm close to Luke AFB in Glendale, Arizona and would like to listen in if they are not fully encrypted. The link is to the RR frequency information page. For non-military systems, I can find the repeater tower that is broadcasting, but LAFB I'm not seeing anything on the Radio Reference...

Hello, after I figured out how to use Sdrtrunk and became more educated on the matter, I decided to create 2 calls nodes (one for each site), and 1 feed to fill a void in my areas BCFY feeds. Everything has been smooth sailing, but recently ive been running into problems after playing around...

Hello, I live not too far away from the Ottawa airport (MacDonald Cartier international YOW) and sometimes can pick up ATC talking and such. I decode fire pages with PDW, and today, I attempted to decode ACARS messages with PDW because it supports that protocol. There are three different...

Hello. I'm new to scanning and newer to SDRs, but I do actually have 75% of it figured out. I know how to use sdr++, pdw, sdrtrunk, satsagen, dsd+, and all that stuff. After I figured out sdrtrunk, I discovered it was comical Ly easy to create a broadcastify calls node and a feed. So I did both...

I have 2 RTL v3 dongle's, on sdr trunk. Michigan MPSCS system. I have a site that has freq on 774mhz and control and other voice channels are up to 853,855mhz. Question is how do I keep getting getting "tuner unavailable" bulls*** from coming up. I need help understanding how to get this to get...

Hi, I output the audio from GQRX to DSD for decoding using UDP. nc -l -u localhost 7355 | dsd -i- -o pa:2 command is used to launch DSD and pipe in the UDP data. The connection is working fine and I am listening to a DMR amateur radio station. However, I found out that the inlvl is usually more...
