Sorry but I am using Linux, not OS X Have you downloaded last gr-osmosdr and substituted lib/sdrplay/sdrplay_source_c.cc with modified source from SDRPlay GIT repo? Regards Franco Spinelli IW2DHW Thank you Franco. I replaced the "sdrplay_source_c.cc" with "http://www.transmitter.com/sdrplay/sdrplay...

Re: SDRPlay with GQRX

Please move hardware frequency 2 or 3 kHz away from receiving frequency. What system are you using? Regards Franco Spinelli IW2DHW Well, I did that and no success! (I can hear the sound with lots of noise and hiss) Although it works with CubicSDR without problems. I'm using OS X 10.11.2 on a MacBoo...

Re: SDRPlay with GQRX

I am using SDRPlay on Linux (Ubuntu 14.04/64 bit) with GQRX and with new CubicSDR supporting it by SoapySDR. On CubicSDR I use 10.099.800 Hz for Offenbach Meteo Rtty reception. This is correct. Frequency is 10.100.800 and required center frequency is at 1000 Hz audio in USB. With this program I nee...

Re: Errors with new gr-osmosdr on OS X

OK, my mistake! I'd selected both MIRI and SDRPlay in CMake file. I set the MIRI to Off. It compiled successfully and now I can play with SDRPlay in GNURadio. But still when I build Gqrx, I can't see SDRPlay in its "Configure I/O Devices" window. Anyway, I selected "Other" and typed "sdrplay=0" in "...

Errors with new gr-osmosdr on OS X

Dear SDRPlay team Although there have been numerous topics about OS X support, gqrx, GNURadio, etc, but here I have another problem: First I should say that I've compiled gr-osmosdr (with SDRPlay support) more than two months ago and also compiled GNURadio 3.7.7 and it worked on OS X 10.11 and detec...

Dear Jon and SDRPlay Team
Have you considered releasing a SDRPlay V2 ?
Is it on your roadmap?
(I want to know whether we can expect a V2 in near future)

Impact of USB cable shield on noise

Hi Here's the results of a very simple experiment I did: I chose two USB cables to compare (images are attached) A 0.5 meter unshielded (blue one) A 1.5 meter shielded (the other one) Then I tuned to a local FM station. You can see the effect of shield on the noise. The picture with lots of noise (w...
