Hi Cecil, It might seem logical, but I am trying to avoid the coax solution because I'd like to avoid an antenna mounted LNA if possible. The LNA cannot be broadbanded, so it prevents me from using the RTL-SDR on other frequencies. And, my purpose is to chase aircraft band DX, so being able to hear ...

Hi All, I discovered, the hard way, that having a quarter wave antenna on the RTL-SDR doesn't work-the computer makes to much rf noise. So, I need to relocate the RTL-SDR away from the computer....actually I could relocate the antenna-but coax is expensive and lossy in terms of being able to copy we...

IC! I can't imagine the time to lock the clock multiplier PLL's would allow scanning at any decent rate. I have experience with clock multiplier based local oscillators connected to rotary encoders, allowing the user to 'tune' using the hand instead of the mouse. Even for frequency excursions of a f...

I believe 5v and 3.3 volts are needed, and I thought I saw power conversion inductors on the PCB-so I assumed that those inductors were attached to switching supplies. And, I thought I heard some chatter about the need to relocate them in order to improve the receivers sensitivity? Perhaps I was mis...

Unless you really need GNU radio for development work or advanced functions, I suggest you use gqrx. Without following any of the instructions that come with your RTL-SDR, make sure you have the universe and multiverse repositories enabled and use Synaptic to install gqrx. It will download all the d...

My translation is that the OP wants suggestions for eliminating the coax run by using a wireless (full duplex) transceiver to transfer digital data that would normally be sent over the usb cable. This is also an area of interest for me, I have a 100 foot tower, with power available for an RTL-SDR in...

Is there any chance your windows punchbox did an OS update? These can wipe out drivers that you added manually.

You are seeing proof, right before your eyes that the RTL-SDR is overloading. It can happen in the tuner as the result of marginal mixer operation or in the A to D converter (when it's maximum total power input is exceeded). With the RTL-SDR's 40 db dynamic range and lack of tuned input filters, it ...
