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?

Re: First contact RTL-SDR.

What exactly doesn't work? As in the code won't run? Post the error message and attach the grc file if you can.

Re: Getting SDR running

There definitely should be a blue light when plugged in, even if the drivers aren't installed. The blue light not illuminating could mean something is wrong with the stick. There is about a 1-2% chance of receiving a faulty stick so contact Nooelec support if you feel it's faulty. But if you're rece...

Re: No Signals RTL2832U 820T

Those spikes just look like interfering noise to me. Is your RTL-SDR connected directly to the PC? Try using a USB extension cable with some ferrites wrapped around it. Perhaps your signals are getting blocked by something. How high are you able to get the antenna? Also can you receive other signals...

Re: RTL Dongle

I have HDSDR and a Kenwood TS440at with CAT Control. I can interface the 440 with Ham Radio Deluxe. I also have Omni-Rig installed. Now, how does the RTL dongle tie into the system? Does the dongle tie into my HF Vertical and is that the RF feed to the computer and the HDSDR program? Also, if the R...

Re: Tuning to Air Traffic Control

The RTL-SDR can tune to 120 MHz without an upconverter. Just tune it in SDR# like you would a normal frequency and choose AM as the mode. For an antenna you'll just need an antenna tuned to around 120 MHz, though if you live near the airport the signals should be quite strong already so any antenna ...
