As far as Bug-detection is concerned I had posted in december some links links and additional information in the Forum

2 rtlsdr on raspberry /spyserver

Hi everyone, at the moment I'm using an orange pi pc plus as a remote server for spyserver ( I also have a raspberry pi 3). I recently added a spyverter r2 to my setup, where I'm using rtl-sdr blog v3 + spyverter + miniwhip antenna for HF and a generic rtl-sdr blue for VHF UHF with its antenna. I also managed to remotely enable the biast tee on the rtl-sdr blog v3 to power the spyverter.

how to tell the spyserver which of the two dongles to use? default is 0 in the spyserver.config but the second? I tried with 1 but without success. from rtl_test -t the two dongles are correctly viewed but have the same serial ... does anyone have experience with multiple dongles?

Has anyone recorded the nist and decoded it?

Debugging my QFH antenna wiring

I've been wondering why I'm only getting less than 1/4 of NOAA APT and Meteor M2 images using GQRX, rtl_fm using the QFH I installed maybe 2-3 months ago. Someone told me to check the wiring which I will do when it warms up. It's below 0F right now. Anyways, this is how I wired it. I checked many QFH build tutorials and I really think I did it correctly. Please let me know - https://imgur.com/a/fzCyV

RTL-SDR Discussion • Re: How do I pick up stations/transmissions,

Foir HF reception first set the V3 to use direct sampling mode. Instructions at www.rtl-sdr.com/V3.

The tuning goes by the usual 100's seperaters GHz.MHz.kHz.Hz.

For example 4625 khz would be 000.000.004.625

RTL-SDR Discussion • Re: SDR# and HDSDR tuning question

Whole spectrum as in DC to light? That would be huge and no radio provide the *entire* radio spectrum yet.

Or do you mean just a restricted bandwidth? The RTL-SDR can provide up to about 2.4 MHz of bandwidth. Other more expensive radios give you more bandwidth to look at.

Within the currently active bandwidth you can just click on a signal and listen to it.

RTL-SDR Discussion • Re: LImeSDR — anyone use? Or HackRF?

LimeSDR is better in terms of the technology. But the HackRF is more well established and probably easier to get going with more previous work done and examples.
