Re: Broadcast FM Reject Filter: loose contacts

The filter was fully functional before I did the resoldering job. I just wanted to make sure the connections didn't come of at some point. By both tightening the nuts and tightening the SMA connectors, there will be some force between the SMA socket contacts and the PCB. Especially if the RTL-SDR do...

Re: RTL2832U v3 install problem

Did you run Zadig as an administrator prior to installing the driver? Rightclick the exe and click "run as administrator".

Broadcast FM Reject Filter: loose contacts

While browsing Youtube I accidentally found this video: https://youtu.be/p4qHqQ1-qY0 Curious as I am I opened my filter finding the same issue. Unfortunately I didn't make a before picture. They used soldering wire which was hard the melt, even on high temperatures. I added 60/40 resin core solder a...

Re: V3 dongle overheating?

I have 3 RTL-TCP V3 dongles. They all become very hot during listening with high RF gain.

Re: SDR# IQ from Sound Card bandwidth

I solved the problem with a different approach: I found a piece of software that's in between SDR# and my RTL_TCP server. In fact it's a splitter that connects to the server and adds an extra listen only stream on another port. I can open 2 instances of SDR# this way.

Re: Wintelive connecting to Linux server? (Tetra decoding)

WinTelive is unstable, too complicated and can(in my case) only decode very strong signals with zero noise. I'm glad I didn't give up looking for a solution. First I wanted to buy an extra RTL-SDR stick but I now got what I want with SDR# and RTL TCP Muxer. It's splitting up the stream into one with...

Re: rtl-sdr keeps active and hot after killing rtl_tcp in Linux

I partially solved it by running rtl_tcp as a systemd service. I can now close it from another SSH session. But it kills the hard way if a client is still connected. I can solve this by starting and stopping it again with no clients connected after the forced kill.

Re: Wintelive connecting to Linux server? (Tetra decoding)

I have GNU Radio connected to my RTL_TCP server, it receives data, MSYS is running and receiving data, but it isn't strong enough for WinTelive to decode. I even played with the gain.
