Re: How to manage freq management file

Check out the documentation they provide. I don't remember exactly where, but they store a database file somewhere, and the documentation shows where it is.

EDIT: Unless you mean the default frequency manager in SDR#. The data for that is stored in the frequencies.xml file.

Re: new RTL-SDR quit working

Can you test it out by receiving other frequencies such as broadcast FM, or anything else other than ADS-B? Watch the ADS-B frequency in a program like SDR# too. One idea is that you could be getting interference at some times of the day or on certain days, which blocks out the ADS-B signals. Also, ...

Re: Using a Raspberry Pi

I'm not sure if anyone has got the RTL-SDR working on a Rpi Zero before, but it definitely works fine on Raspberry Pi 1, 2 & 3. On the Rpi 3 you can even fairly smoothly run GUY programs like GQRX.

Adding a rotary encoder is possible, but you'd need to figure that out on your own.

Re: [Newbie] Help on choosing coaxial cable.

Great explanation Kevin! I agree that RG-6 coax is generally the best to use. It's cheap, readily available as it's often used in satellite TV installations, and low loss on the frequencies that the RTL-SDR can cover. The downside is that it is usually thicker and more rigid (harder to work with) co...

Re: Help Me Choose My Next Rig

I wouldn't bother with the XTR+ E4000 dongles, unless you actually need the higher frequency range that they provide. The R820T2 based models are better in most cases, and much cheaper. The only reason the E4000 XTR+ model costs so much is because the chip is now rare, since that chip manufacturer w...

Re: About listening to several analog audio stations at once

Like a scanner program? On Windows you can use SDR# and the Frequency Scanner or Fast Frequency Scanner plugin. On Linux or Mac you could use rtl_fm, and use it in scanner mode with the squelcher. Have a look at the guide at http://kmkeen.com/rtl-demod-guide/, and look for the Airband Scanner example.

Re: RTL_SDR missing components?

Those components were for the IR LED and LED light, but we've removed them on ours as they are not needed, and have no purpose especially since we use a metal case. C23 can be 10nF or larger. I wouldn't operate the dongle as you have, with C23 missing. The purpose of C23 is to block the 5V bias tee ...

Re: sharp sdr# does not show a devise in conroller box.

It looks like you havn't run both zadig and install-rtlsdr.bat. The windows driver screen shows no driver installed, and the folder shows no rtlsdr.dll file. When you run the bat file it should download zadig as well as the rtlsdr.dll files. Is there something preventing the bat file from running no...

Re: Marine VHF radio and weather do not work, FM does SDR#

If you are seeing the signal on the waterfall then the device is working correctly, but you might have your software configured wrongly. Marine VHF is usually in NFM mode. You might have the squelcher turned on, or the filter bandwidth set too small. Upload a screenshot of your settings so we can ch...

Re: 88-108mhz fm signals on 24 mhz

Signal Imaging, very strong signals can show up at different frequencies sometimes on the RTL-SDR. To fix it, reduce the gain, get a cheap FM trap, or buy a more expensive SDR with more ADC bits like the Airspy or RSP which have 12-bits.
