The user guide for the rtl-sdr dongle mentions filters: I gather I should have a minimum of an LP and an HP, selectable, both with cut off at 14.4 MHz or a Spyverter, and an 88-108 MHz bandstop, Otherwise aliasing and FE overload may be a problem. Are there any good diy filter designs out there, pre...

Re: Help! Using rtl-sdr dongle v3 + sdr# but no real result

I was trying for something under 30 MHz: I realised I don't even know if there are any stations near enough to hear a signal here. I tried the dongle on SDRuno/android and it played some FM at 92.4 (Swedish Radio programme 1), so the dongle works. Antenna: I clamped 4-5 meters of 2mm² copper wire fo...

Sdr# install-rtlsdr.bat doesn't work, wrong url

The install-rtlsdr.bat file in a 64bit sdr# distro downloaded yesterday fails since it references the disused url "http://sdr.osmocom.org/trac/raw-attachment/wiki/rtl-sdr/RelWithDebInfo.zip". Also, the manual driver installation instructions for sdr# on rtl-sdr.com tell you to look in the x32 subfol...

Bulk in interface (Interface 1) gone but zadiq sees it

I had some problems with sdr# and my rtl-sdr dongle, so I accidentally removed bulk in interface 1 when doing stuff in device manager. Sdr# now works, but zadiq sees interface 1 and claims to see a driver there, named RTL2832U_IRHID (V8664.1.1019.2010). Huh? What should I do to make interface 1 reap...
