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...

I have SDRTrunk 0.6.0 beta 2 and it keeps telling me that it's not compatible even though apparently from the few forum posts about this that I read, they all say it's compatible, but the software begs to differ. Should I just return my SDR for any older one or is there a proper fix?

Hello Everyone! I have been trying for the past 24 hours to get my SDRtrunk to work with my RTS-SDR model V3 and I can not hear any stations. I downloaded SDR++ to see if the dongle was picking up stations and it is. I am obviously missing something I just don't know what. My control...
