Newbie to the world of SDR. I have DSDPlus Fastlane working with a SDPlay RSPdx. I have it decoding P25 after a day of research. How do I tell FMPP which antenna to use and to turn on the bias-t?

Thanks,
Mike

From Notes.txt file included with FastLane --

FMPP 1.0

DSD+ compatible SDR software for SDRPlay RSP2 receivers.
Other SDRPlay receivers are not supported, but some functionality may be possible.

Operation is similar to FMPA; refer to FMP.txt, FMPA.txt and
FMPA feature updates documented in this change log.

Use Notepad to add your SDRPlay serial number(s) to the FMPP.cfg file.
