SDRTrunk Second tuner with SDRTrunk error

[KM6IIN]

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?

Is it showing as enabled in the tuner tab?

It is, This is what I am seeing on the tuner tab.

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.

What happens if you start the rtl dongle first, then start the Rsp?

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.
