Although there are methods for supplying +5V to a receive antenna on the
DBSRX daughterboards, I just wanted a final sanity check to verify that
there is not something similar for the RFX (in particular 1800)
daughterboards before I go and buy an external bias tee.
I’ve looked in the archives, at the schematics, and at the board itself,
I’m not a hardware expert so I could easily miss it.
