SDRPlay RSP1A support?

[Ron Webb]

I received an SDRPlay RSP1A receiver today and I am curious if the latest "master branch" version of SDRTrunk includes support for this or should I change to the SDRPlay branch? I am currently at work, so I haven't had a chance to plug in the RSP1A to see if it works out of the box.

I have tried to download the SDRPlay branch and tried to compile it but I'm having problems compiling it. It took a bit of trial and error but I upgraded from Bellsoft's JDK 17 Full to their JDK 19 Full. This reduced the number of errors when attempting to build but I still have an issue. Below is the results I get when I try to build.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

In the message above, you may see that there is a hyperlink… I have actually moved this file to a website so that it can be viewed if it can help point me in the right direction to solve the error.

Just as a small follow-up, despite that error, it appears that it has built the distribution. While making sure to make backups of everything, I changed out my previous master branch build with the SDRPlay branch and restarted SDRTrunk. It appears that it is operating just as well as the master branch ran. Again, I am physically at work and not at home. I will try to plug in the SDRPlay tomorrow and see if it is recognized. My main reason for wanting the SDRPlay is I am having to use two separate RTL-SDR dongles for one of the two systems I am monitoring due to it using more than 2.4 MHz of bandwidth; the limitation of the RTL-SDR.

Despite the SDRTrunk being built from the SDRPlay branch, apparently whatever is crashing might be important. I cannot get SDRTrunk to recognize the RSP1A tuner.

Hi,
This is what Denny answered on the Discord General channel about 2 weeks ago about "ETA for official SDRPlay devices support":

"Yes, that will be the first 0.6.0 Alpha release.  The branch (#52) is 98% ready.  There's an issue when you disable and then reenable an sdrplay tuner that I have to resolve and then it will be ready.  I'm trying to wrap up version 0.5.0 as a final release before I introduce any more new features.  Hoping to wrap up 0.5.0 this week."

I downloaded and compiled the "version_0.6.0_development" yesterday and have been running 3 SDRPlay RSP1a's on it.

I compiled for Ubuntu on BellSoft JDK 19.0.2+9 and did not have an issue.

Nothing I'm doing is allowing it to compile properly. I suck, probably.

Step by Step instructions that you took to get it to compile for you, maybe?

I appear to get it to work on Windows but not Linux. Despite the SDRPlay API running, it doesn't know how to find it on Linux. On Windows, I had to put the SDRPlay API directory into the system PATH before I was able to get the software to actually start. It needed to find a particular DLL file.... which is a Windows thing, not so much a Linux thing.

I am able to compile the software but not without an error. I always get an error of > Task :jsdrplay:test FAILED. It still creates the final program.

I am having difficulties compiling the software on Windows for some reason, despite having the same Bellsoft Java 19.02 FULL JDK installed on both Windows and Linux. I am able to compile it on Linux, copy the program to Windows and start it there. Weird.
