Friends,
I'm a beginner, so I have doubts that are sometimes considered stupid.
I use an RTL-SDR v3 with "Wideband LNA by RTL-SDR" and "Band Stop Filter 88-108M".
I'm trying to use SDRTrunk, but I haven't found any configuration in it to activate "bias-t".
Is this possibility available in this software?
I appreciate any help!

LNA should be hooked to SDR, then band stop. Check for voltage on the SMA, CMD line can turn it on if it's off. I check all devices in line to see if they block, short or pass voltage. SMA DC blocks are cheap insurance.
Good Luck!
