Two RSP's, same program

I have a RSP1 and an RSP1A. I have no problems running them simultaneously, using two separate instances of a program (in my case, the program Waterfall Bandmap). Another ham radio program, N1MM Logger+, now directly supports ExtIO-based SDR's, such as the RSP's. It also supports running two SDR's s...

RSP Driver Digital Signature Problem

I have an RSP1 and RSP1A. They work fine on one of my PC's, but having trouble getting the current drivers installed on the other PC. The funny thing is that I had it working a year ago with the older MIR API and drivers on the same PC. The error message is "Windows cannot verify the digital signatu...

Re: RSPduo dual API question

Didn't find the RSPduo API spec or API binary on the Downloads page. Where can I find it ? I now have a (free) DLL for the RSP1, 1A and 2 that works with the Afreet Skimmer Server. No doubt, changes will be needed to support the duo.

Thanks,
Steve

Skimmer Server support for SDRPlay RSP's

VE3NEA's Skimmer Server (http://www.dxatlas.com/skimserver/) now supports the RSP1, RSP1A and RSP2 using the driver at http://www.kkn.net/~n2ic/SDRPlayIntf.zip . This provides an easy way to get local CW or RTTY spots using your SDRPlay device, and send the spots to the Reverse Beacon Network (www.r...

Re: Resampling

Thanks to Steve Andrews and the SDRPlay staff for their help. After some hair-pulling, I now have a DLL working using the mir streaming API that samples and decimates to 192 kHz, feeding I/Q samples to VE3NEA's Skimmer Server ( http://www.dxatlas.com/SkimServer/ ). I plan to make this available for ...

Re: Resampling

Thanks ! I think I see what to do now. It helps to walk away and think about these things for a while.

Re: Resampling

At the risk of showing just what a poor developer I am ...

Can anyone point me to C++ code that uses mir_sdr_StreamCallback ? I have looked at Steve Andrew's C# code, and have spent a day trying to figure out how to do that callback in C++.

Thanks,

Re: Resampling

Thanks for the response. My concern is that streamcbfunc is going to start receiving I/Q samples before mir_sdr_DecimateControl has been acted upon by the API. Therefore, the upstream user of the I/Q samples doesn't know when the samples reflect the requested sampling frequency/decimation factor. So...
