sdr

Sorry for the vague title. I want to get into shortwave radio, but I am not sure where to start really. I found my interest in it through North Korea, they have a broadcast called Voice of Korea as most of you might know, and that's how I found out about shortwave. Had no idea this medium...

Hello all! I am looking for someone in the Austin area who's familiar with setting up SDR Dongles to receive / decode P25 Phase I/II data/signals in SDRTRunk or one of those. I've done it in the past but it was several years ago, and I just don't seem to have the ability to wrap my head around...

I have been running my sdr box on a 4th gen Intel i5 and found a Dell R360 for sale $50. Specs are 2X Xeon E5-2620 v3 cpus, 65 gigs of ram also had 2 Broadcom Quad port nics and a LSI sas card. One broadcom card was removed as well as the LSI card. It has 8 2.5 inch slots of which only one is in...

Well, I hope the title caught you :) I am currently working on my diploma project in Visual Communication and Programming and I need YOUR help! My goal is to create a platform/framework for signal data visualization (and interaction). In simpler words, it's like thermal/x-ray vision but for...

can someone tell me will this amplifer let me listen to vhf and uhf frequencies by amplifying them. Channel, Cascaded Ultra-Low Noise Amplifier

I'm very new to the world of SDR, and I am using a nooelec sesdr smart, but the problem I'm having is that every time I start the channel, it will play perfectly for about 30 seconds, and then it will stop and the only channel in the now playing will be the control. The only way to fix it is by...

Hello again, unfortunately I'm having another problem with digital signals (dmr, tetra) with airspy sdrsharp 1921 and sdr-trunk 0.6.1 final version. I had an old i7 laptop with windows 10 where everything ran perfectly, but unfortunately the video card broke and I had to buy a new laptop. I took...

I found an old RadioShack "Pro-97" while tossing junk out and had an extra antenna suitable-ish for CB, and had a moment of curious inspiration about some of the more incessant yappers I've been hearing lately. There's been some conversations here about whether or not some of these jackwagons...

Hello everyone! I bought an AntSDR U220. But can't figure out how to start using it. There is too little information in the MicroPhase github repository (MicroPhase - Overview). If anyone has experience with this device, I will be grateful for any information! Regards!

I working on fine tuning my SDR Trunk Calls feed and the feed sounds choppy like it keeps dropping the call, need some help maybe the tuner needs retuned

Hi, Im new to direction finding and radio topic in general. I got into it 6 months ago because Ive realized how much we are surrounded by the electromagnetic waves and how much a signal can tell. So now im here doing my bachelor project about RF data visualization in VR/AR and sound...

I have installed op25 but I get a no attribute “get gain names” error… I was I guess completely unaware that op25 doesn’t have a gui. What programs can decode p25 phase 2 that can run on a raspberry pi 3 that have a easy to navigate gui? Thank you! Please help

So I’m trying to host a stream and calls with two dongles on a Pi, is this possible? Calls are separate from an audio stream correct? Would be a P25 Trunked system. Thanks

This Small PCB Assembly allows for use of a short whip antennas at frequencies below 10MHz. These signals are often undetectable due to the antenna impedance ( >1Kohm) compared to the 50 ohm impedance of a typical receiver. This device provides a suitable match to boost signal input into the...

hello i would like to ask where it is possible to purchase sdr in ottawa. thanks a lot.

So yeah I’ve been a ham for about ten years but have just recently been getting into SDR stuff… I mainly need a good quality SDR radio for HF stuff, 3mhz-54mhz. I wouldn’t mind to monitor vhf/uhf stuff too.. So should I get a RTL Dongle V4 with a dipole kit to start out? Or should I just get one...

I have unitrunker set up with two SDRs, trying to listen to mass state police in the eastern part of the state which runs motorola smartzone analog in the 800mhz range. I have the signal VFO which appears to be working but the voice vfo is staying parked and not producing any audio. I have...

I purchased an RSPdx several years ago, and was using SDRuno on Win10. It worked great! I made the mistake of allowing my Win10 machine to access the internet, and was suddenly being forced to do things by Microsoft that I really didn't want to do! So I decided to dump Win10, and installed...

Hello everyone. I have a thing called LibreSDR. As far as I understand, it is something like a clone of ADALM-PLUTO from Analog Device. I have never worked with such devices, but the opportunity and need to use it in my work arose. As I understand it, this thing can scan a given frequency and...

Hey everyone! I just got my hands on the new hackrf h4m portapack version, and I am absolutely thrilled! I've been diving into this hobby of sdr devices, and this is my first high performance sdr. Before, I only had an rtl sdr v4. I am really impressed by this device, and it also looks amazing...
