Over the last year or two, SDRplay and others have generated a lot of applications material in the form of documents, articles and videos – these are designed to make it easy to get up and running with RSP receivers from SDRplay. Attempts to use the YouTube playlist system to catalogue videos...

I have this app, LTE Discovery, in my phone which tells me the LTE UL frequency and power so I went with my SDR and measured the received signal at that frequency and it matched. Now, how can I be sure this is the transmitted signal from my phone? As I made a call to and from this phone and...

Hi Guys Sorry if this has been asked before, I tried a search but didn't find what I was looking for. Just got started with SDR's and have the RTL-SDR dongle loaded with SDR#, this works fine and I ca hear transmissions fine. I then tried decoding ACARS with the Acarsd program and I can't see...

Over on YouTube, ICAS enterprises have posted a video demonstrating “Signal Adaption” using an RSPduo. This is one of the new capabilities offered by a Dual-Tuner SDR and is a good example of the kind of feature SDRplay will be adding to their own SDRuno software in a future release. This...

I searched and have not seen this posted on here. It has been as issue for a while of not having such a plugin. I was using tinytask to start SDR# and now no longer! This plugin will autostart (play) SDR# after five seconds. I am using rev 1666 and the plugin is working...

Is anyone else experiencing an issue on UniTrunker’s website at the Downlaods page? I went there to check if there was any new versions and the entire Downloads section is giving me a “404 - Error” message like the site is down. Thanks!

So, I'm using RTL to decode a P25 phase 1 transmission. Sometimes (rarely, like once every minute or two) I get a clear decoded output. The rest of the time, I either get TDULC or the transmission is choppy. I'm using UniTrunker to do all the other work, no SDRSharp or anything. It sounds a lot...

Hi ... I got my first SDR dongle (just a cheap $10 thing off ebay), and to my surprise I successfully installed the SDR# on the pc, as well as SDR Touch on the phone. My question is .. I've only been able to pick up a couple FM stations, nothing on MW and the weather station (barely) so far. Is...

Is there a simple easy to follow setup for using SDR with the UNITRUNKER program. I have tried the UNITRUNKER instructions that your supposed to follow when using the UNITRUNKER program but there is so much there that I windup getting pretty confused and frustrated with it. I've gotten it to...

I have had two RTL-SDR V3s for over a month now that have been working great. Since they have been awesome I decided to get an AirSpy R2. I got the AirSpy in today and hooked it up. First, the USB cable was DOA, no problem I have plenty of micro USB cables to go around. So now I start using the...

I'm trying to use trunk-recorder to record site 28's traffic from this system South Dakota State Radio System Trunking System, Statewide, South Dakota - Scanner Frequencies...

Does anyone have any information or insight they can share with regard to using a SDR dongle to receive data being transmitted on TTC frequencies (particularly the CIS data channel 423.7375?). Myself and a friend are looking into this using a SDR software but he thinks that the radio data output...

I'm new here, and new to SDR, and I'm having the time of my life. Way back in the late 1960s, the USAF had me sitting at a console, staring at VHF and UHF frequencies on a spectrum display, for reasons I can't really discuss still. My guess is that console cost half a million dollars or so...

I am trying to monitor a number of different radio signals in a tight bandwidth at once. I would like to be able to use one device, like the SDRplay devices that can monitor 10MHz and separate the output into multiple streams around the desired frequencies. Their software allows this but only...

Hello everyone, my name is Wolfgang, located in Germany (DH1AKF). With assistance of a hard working programmer, Pavel Demin (Belgium, Catholic University Louvain), we developed together a stand alone solution, consisting of the Red Pitaya and a STM32F7Disco board with touchscreen. I invite you...

Hey RR users, I've been playing with SDR, And it's really a lot of fun, and a great entrance to the Radio world. I'm wanting to set up a Discone Antenna for general listening, I'd obviously want this on my Roof. I don't come from any engineering or electrical backgrounds, However I know the...

Hi all, I hope the mod will be OK with this post due to the inclusion of SDR use/integration, and that it may be of interest to those that are interested in radio tech (like me) Since TPS went encrypted I have been trying to use other technologies to make-up for this gap in information, so I...

Hi everyone, I am new in the HAB world and I want to track one with a SDR. I am following the Pi In The Sky Manual (http://www.pi-in-the-sky.com/data/uploads/pits-manual.pdf) and the ukhas web to configurate the SDRsharp and the dl-fldigi but I am having some troubles to decode the signal. I...

Hi i have 2 SDR's using unitrunker and dsd+ fastlane to pickup an edacs96 trunking system. all working well. My main question I would like to be able to scan through a list of analog non trunking stations for fire brigade and other standard frequencies. I have seen I can use sdrsharp to tune...

Before I can download a SYSTEM into unitrunker, you have to know the system ID number and the SID number, example: Texas Wide Area Radio Network (TxWARN) (P25) System ID is BEE00-1A7 and SID is 4563. How do I find this same information for system Texas Wide Area Radio Network (TxWARN) Motorola...
