Sorry... the above is misleading.  To clarify:

If you look at the Molex connector from the front, with the locking tab
at the rear, ground is supposed to be on the left pin and RF/DC+ on the
right pin.  That's what we've tried to define as the TAPR "standard" for
using those connectors.

It makes sense to call the left pin "pin 1" and the right pin "pin 2"
but unfortunately, the pin numbering on the schematic is the reverse --
it shows ground as pin 2.

According to the TAPR convention, J1 and J2 are installed correctly, and
J3 and J4 are reversed.
