Re: HackRF - Antenna for getting 2.4 Ghz frequency

2.4 GHz is used by WiFi, so any 2.4 GHz WiFi antenna should work well. You can find these types of antennas anywhere, try Amazon or Ebay.

Re: Newbie needing help ?

For a beginner on Linux i'd recommend GQRX, which is a standard SDR GUI https://github.com/csete/gqrx (git install instructions are on that page too). I wouldn't bother with GNU Radio unless you are looking to do some serious signal processing work. As for Linux driver installation the instructions ...

Re: Help with SDR and Satellite Reception 137 MHz

The RF gain setting is in the gear icon settings. You should increase the RF gain from zero, push the slider to about 3/4 of the way to maximum, or click the tuner AGC button. Don't check the RTL AGC box. These are the most important settings for reception. If the RF gain was set to zero, you won't ...

Re: Help with SDR and Satellite Reception 137 MHz

Hmmm did you turn up the RF gain in the configure menu of SDR#? By default it is set at zero. At zero gain it will receive strong WFM stations, but might not receive your APT signal. The recent changes in SDR# won't affect your reception of the signal. Though, if you want the latest sdrsharp can alw...

Re: Help with SDR and Satellite Reception 137 MHz

What exactly is the difficulty you are facing with SDR#? What is your APT satellite antenna?

Did you set up SDR Console using the instructions on the quick start guide?

Re: Siginal Strength

I think the command line tool rtl_power is what you want. That will log a chunk of bandwidth and record power values for a bin size to a csv file.

Re: Installing CTCSS decoder.

The way SDR# plugins are installed recently changed in the new version. There is now a plugins.xml file that you should add the line to now instead.

Re: Auto anti-drift calibration using pc clock or noah?

You can always use the software kalibrate to get an accurate PPM measurement from GSM signals. Problem is accuracy drifts as the dongle heats. Not sure if you could sync them with PC clocks, would be a good question to ask on the rtlsdr IRC channel (http://webchat.freenode.net/?channels=##rtlsdr), l...
