This is fairly deep technical question that applies to all SDRs, purely my curiosity, posting on the chance there is an SDR expert out there who can answer it in a simple manner, or post a hyperlink... I have always wondered how the raw ADC samples in the RTL-SDR dongle (28.8 megasamples/second?) ar...

The RTL-SDR.com brand of FM trap does an excellent job of cleaning things up when there's a FM broadcast tower nearby. It even helps me receive signals with a cheap handheld VHF transceiver (5W) that is susceptible to out of band overload. However, transmitting through a filter like this is a dicey ...

I just started to use the Spektrum software with the RTL-SDR dongle to get a picture of wide sweeps of the spectrum. Really impressed so far. One thing though is I wish there were a way to scan the spectrum below 24 MHz, using direct sampling on the Q branch, like you can do in SDR#. That way I coul...

There is one catch to the new SDRplay "trick", though. If you try to run the Spyserver remote software for remote access to the SDR, the SDRplay won't be found, and I haven't been able to find a workaround in the configuration file to force it to "see" the SDRplay.

another one solution by Christophe Marchand bring back ExtIO devices support for SDR# 1600+ versions, also it support latest SDRplay ExtIO dll from official site dowloads, just unpack SDR#_ExtIO_v1.1.zip to SDR# folder, select UHD/USRP source and choose path to *ExtIO.dll or put it into SDR# folder...

I have one of the "official" RTL-SDR.com broadcast band filters, which really helps at my location, since there is a 1340 KHz tower just a half a mile away. Without the filter that AM station shows up all over the place. I would like to use the same filter with a low power (1 watt) HF transceiver (r...
