Re: What is on everyone's SDRplay V2.0 wish list?

A way to switch external filters or aerials depending of the frequency tuning.
Too many internal filters will increase cost and induce problems in the overlapping zones.
May be the use of switched notch filters inside the SDRplay would be a better solution.

Re: Would wrapping the unit in AlFoil tape help shield it?

It is very simple and cheap to try this. My SDRplay is wrapped in aluminium foil since I have it. As said it can only improve so I keep it like this. One of my goal when I did it was that in the FM band with no aerial it receives as little as possible. On that ground it improved a lot. A thing I fou...

Re: will upgrade to 12 bit sdrplay help me?

Hi
There is no mystery as it is frequency modulation well known for having a demodulated SNR better than the RF SNR.
The improvement is related to modulation index and sadly can be quite low in FM stereo .

Re: SDRPlay Performance

I'm new to this board and to SDRPlay and I'm having trouble getting my SDRPlay to work without choppy audio. My system is Windows Vista 32 bit, 4 GB of ram and a 2.40 GHz processor. Hi I never used vista but when I installed Windows 7 64 bits on my quite old PC I had for years problems with any app...

Re: will upgrade to 12 bit sdrplay help me?

Hi
FM reception with the SDRplay is definitely better than with any RTLdongle.
Now noise is a well known drawback of FM stereo so don't expect miracles.
The 12bits dynamic range mainly improves reception of weak signals close to strong ones.

Re: Raspberry Pi 2 + SDRplay: Setup Guide?

Hi I made various test and comparisons between Orange PI and Intel based mini PC's for SDR. Using gqrx under Linux and SDRtouch under Android and various softwares under Windows 10. My conclusion is that Intel devices are much more suited due to the mathematical computations involved. May be a good ...

Re: ATV decoding with SDRplay

Analog satellite uses FM modulation the plugins are designed for AM modulation and useless in that case.

Re: Two Receivers

Hi
That is a good question.
With 2 identical RTLSDR dongles I had problems too.
But sometimes it is simpler to use 2 or more devices instead of a complex mixing/switching antenna setup.
As a bonus you can run them at the same time .

Re: SDRPlay and DRM

There is one thing I forgot to tell when using Dream to decode DRM. It may be useful to disable any kind of AGC on the software driving the SDRplay Dream does take care of that in a way more suited to DRM signals. Actually I'm using SDRsharper feeding Dream via VB cable : http://vb-audio.pagesperso-...
