If I listen to the control frequency I don't hear anything but listening to "alt control 2" I start hearing audio. I'm also hearing traffic and seeing talkgroups from a neighboring city but those aren't even part of the talkgroup aliases I imported from RR? I'm using an RTL-SDR V3 + RTL-SDR V4...

so i built this linear loaded SWL antenna, a project i found on the swling website, which involved getting a a NooElec 9:1 balun in the middle of two 15ft pieces of romex bound at the ends in a way that it effectively makes a dipole with 45ft elements. this balun is not made for any kind of...

I just tried to visit the Nooelec website, where I bought a couple SDRs previously, and it seems to be down at least for me. How about you guys? If it has been down for everyone, is that recent? Or has that been going on for a while now? I'd hate to think those guys were going out of business.

So far I have used the BCFY RPi4 appliance image and Trunk Recorder with 1 SDR for sending a Calls feed for a single P25 trunked system. My config file has a single device entry under "sources", and a single system defined in the "systems" section of the config file. I'm pretty sure I under...

HI All I'm running into a huge problem that I've been trying to find a solution to for the entire day. If you don't feel like reading, this video describes my issues I just built a new computer to run some SDR projects. This PC was built for this and I think Murphy has his hands in this...

This is the USB unit I bought for my first venture into SDR radio. Unlike some others, it's packaged in a metal housing, which is slim enough to allow two dongles to fit in adjacent USB sockets. It comes with three antennas, including two fixed-length and one telescopic which screw onto a...

Ok, I'm going to keep this simple. Can anyone point me to an online help or video on how to use Unitrunker? I have the control/signal radio working, but for the life of me I can't get the second SDR to actually follow the signal nor have I figured out how to listen in on a specific call group...

So, I'm trying to calibrate my NooElec RTL-SDR RTL2832U & R820T for SDSharp, using the stock antenna, which actually gets pretty darned good reception. Problem is, upon calibrating my signal, so it sits center of the peak, I get this high pitch noise. If I readjust the signal so it sits a bit...

I was one of the many people who struggled with getting the NooElec RTL2832U/R820T getting it to work. Specifically, getting SDRSharp to enable it as RLT-SDR/ USB Vs RLT-SDR/ TCP. I edited,reinstalled, and struggled. Finally, i went to Nooelec's website, and found the CORRECT install package for...
