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: Why no cheap 2-3 ghz sdrs?

Not sure why you're not seeing results, I get 136 results. Here is one example http://www.aliexpress.com/item/brand-ne ... 33899.html.

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...

Re: DVB-TSTICK serial number problem

This is for watching TV right?

Don't know if it's the same software but this link from a Chinese dongle factory http://download.buytra.com/driver/SPC-0155-Driver.zip comes with a serial number. If you've installed the DVB-T drivers its better to use www.progdvb.com/ for TV watching anyway.

Re: Why no cheap 2-3 ghz sdrs?

Main reason is that the RTL-SDR (e4000, r820t) is an SDR by accident. They're cheaply mass produced in China for a massive world market for watching DVB-T Digital TV. Some clever third parties hacked the dongle and found it had an SDR mode that could be enabled in software and here we are. HackRF an...

Re: ADS-B signal

Not sure if that is ADS-B, it could be if it looks like lots of short pulses. Why don't you try ADSB# or RTL1090 and see if it picks up ADS-B packets?
