Hooked up a second dongle. My primary is an RSPlay and this new one is an RTLsdr. I have the RSP Monitoring 2m and would like to have the RTL on 70cm. SDR Trunk recognizes the RTL but whenever I try to select it as the prefered tuner I get this message. Anyone have a solution to this?

If you unplug the RSP and start SDRT with only the R820T, does in still say it is unavailable?

Have you tried a different usb port? If not try that, I have a usb port on my desktop that refuses to talk to a R820T even though it loads, when all the other usb ports work fine.

Is it plugged into a usb hub? or straight to computer. Hubs can cause issues if not a powered hub.

Ends up working out the same, when I only have the RTL plugged in SDRt recognizes that the RTL is plugged in but I still get the no tuner available even though the RTL is selected. I then switched the RTL to the port the RSP was using and still had the same issue.

Side note, RTL works just fine when using SDR++

A USB hub is not currently being used.

Did you have any problems setting up the RTL with Zadig? Might try re-installing the driver with Zadig.

Make sure your other channels don't reference it as the preferred tuner, and define the frequency range to something narrower, like 453.0 - 455.0

Alright guys, I got it working! So I installed SDRtrunk on the laptop and the RTL seemed to work fine but I realized on my desktop I was using the old Stable build. I installed the nightly build on my desktop and now everything is working just fine!
Thank you all for your time with helping me try to troubleshoot this.
