Re: RSPA1 : Sampling rate vs Bandwidth

If you use the rule to make sure the IFBW is equal to or lower the final sample rate (after decimation), this will avoid any aliasing issues.

Re: RSPA1 : Sampling rate vs Bandwidth

The IF BW values are fixed to those that I listed for both Low IF and Zero IF mode. From a processing load perspective (as well as visual) it would make more sense to specify 2 MHz sample rate, decimation of 4 and a IFBW of 300 kHz this will give you a final sample rate of 500 kHz and only 100 kHz e...

Re: Frequency shift for LNB/Es'Hail

Maybe my misunderstanding, but there is no fault with the RSP product or the drivers. As long as the specified RF frequency to the RSP API is within the 1 kHz to 2 GHz range that we say on our datasheets, then the API and the RSP will function correctly. SDRuno is a free download, it's not part of o...

Re: Raspberry Pi4B

I have tried many SBCs and have them all working with RSPs... RPi3 - RPi4 Asus Tinkerboard Beaglebone Black Orange Pi Odroid C2 Odroid XU4 Pine64 etc. I got the 4GB version of the RPi4B and now have just put it in a case with a fan. CPU Temp is constant at 46deg (it was running closer to 80deg last ...

Re: Raspberry Pi4B

Yes had CubicSDR running this evening - looks like I can run up the sample rate higher than with RPi3B+, but only a quick look. Waiting for fan to arrive before being able to run proper comparative tests.

Looking good though. We'll put an image together when time permits.

Best regards,

Andy

Re: Diversity Demo in Xenia

We have been working hard on getting 1.32 released and after Dayton there were some changes that needed to be made to make the system more robust. The software has been with beta testers and we're working on the last few issues and hope to get it released asap. Yes, I was convinced with our early te...

Re: SDRplay RSP2 appears to be useless on Ubuntu

You don't need to register to get the API if you don't want to - go to http://www.sdrplay.com/downloads and get the API directly. Before executing the .run file you will need to make it executable first by using chmod 755 filename then you can run the installer as you can see in this video... https:...

Re: possible RSPduo driver problem

Please note that SDR-Console uses API 2.13 and this only supports single tuner mode. SDRuno supports API 3.x so therefore can support master/slave mode as well as single tuner mode. If you see the same problem with SDRuno, then I would raise a support ticket (http://www.sdrplay.com/support) SDRplay ...

Re: Scanner Is Pretty Good, But...

The SDRuno scanner is purely a channelised system. If the specified step size is smaller than the specified audio bandwidth and if the threshold isn't optimised, then it could settle on the sides of a signal, but if used correctly that's not really likely.
