I did a "science" experiment where I ran coherent data collection from two RSP2 under Ubuntu. I wrote a server using the 2.13 API directly. Basically the SDRPlay API doesn't work with multiple radios on a single process with multiple threads. You simply are not allowed to set the device index in a s...

I have 2 rsp2 and a rspduo I got for an experiment. If it's helpful I wrote this rsp "directory" code to dump all the radios and some info. If you know how to compile and build c++ code, this may be useful for trouble shooting. #include <mirsdrapi-rsp.h> #include <iostream> #include <stdint.h> using...

My application relies on phase coherence between tuners and I'm waiting for v3.0. I have a duo and I'm in the process of coding with v2.13. Is it possible to be a beta tester?

What ever. I'm happy just going away.

You do know that a git repository gives you access to the latest version?

I second the request to publish the answer given to the OP. It's most frustrating when engaging a question to have it vanish down a private conversation.

In the limit someone might care, it seems it's not possible using the common clock input on the RSP2 to phase lock two radios. Internally the MSI001 tuner uses a Fractional-N synthesizer (or FLL) and not a PLL like I had assumed. Only the average frequency is maintained between the radios and not th...

Not certain what the issue is but doesn't a sampling rate twice that required only imply that you're over sampling? Why is this a bad thing?

Okay, had a very helpful interaction with tech support and I should post a data dump here. The main source of my confusion was due to my external clock decided to put out 20MHz rather than the required 24MHz while I wasn't looking. The symptom using an external clock too far from 24MHz is the radio ...

Using an Hp3325B function generator set to 24Mhz sine wave @ 1.5 volts peak to peak and the coupling circuit consisting of a 10nF capacitor with the radio side connected to ground through a 1.18k resistor[1] I get the following behavior. The external clock-in line is connected first. I then plug the...
