Re: Contact Rafael Micro

I don't think they're interested in talking to individuals. They only seem to deal with factories requiring very large quantities. They also only release datasheets to those factories and not to individuals.

Re: Drivers

Did you perhaps change the RF gain in the configure menu (cog icon)?

Re: 2 Nooelec Dongles wont run same time

Did you select the second dongle in the drop down menu? This is what I do 1) Plug one dongle in and start one SDR# session. 2) Plug in the second dongle and open another SDR# session and start it. If I get that error I go to the configure menu (cog) and select the second dongle in the drop down menu.

Re: Locks up after a few seconds

Are you running on a long or poor quality USB extension cable?

Re: 2 Nooelec Dongles wont run same time

What happens when you try to start two? Usually you can just select the second dongle from the configure menu in SDR#.

Re: Keenerd drivers for Linux?

Clone from here https://github.com/keenerd/rtl-sdr.git

And the instructions used to compile the standard RTL-SDR drivers should be able to be used to compile Keenerds. Those instructions can be found at http://sdr.osmocom.org/trac/wiki/rtl-sdr.

Re: R820T2 help

Have you tested the R820T vs the R820T2 with the telescopic antenna? My own tests seemed to show that the R820T and T2 were about the same with ADS-B performance too. But the tests by the hamradioscience.com guy seemed to show a good improvement.

Re: SCMO/SCA channel on FM comercial band

After testing a little more I think I know the exact problem you are having. VBCable seems to distort the output audio a lot. When I switched to Virtual Audio cable I was able to get a proper spectrum of what you should expect to get. I think VBCable is restricted to 48 kHz of bandwidth, which is wh...

Re: SCMO/SCA channel on FM comercial band

Ah I think I see what you are trying to do now. The problem seems to be images of the main audio blocking the subcarriers. SDR# doesn't have audio bandpass filtering so I suggest you download and use HDSDR which does. Then bandpass filter the RDS or SCA signal and pass that audio to SDR#. I attached...

Re: The "Black Box"

I'm looking for a way to receive and view CCTV video. I've seen something on a russian website but I can't get anything to come in to confirm that its working. These devices were designed to be TV tuners, so you would think this would be easy. It all depends on what frequency the CCTV camera is tra...
