Hi all, 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, but I'm not a hardware expert so I could easily miss it.
Only the DBSRX has an internal bias tee. None of the other daughterboards do.
