      Hi Matthew,

      I have only ever build the original v6.0 board, but just taking a quick look at the two schematics appear to be identical including the component numbering, except for R17 in the oscillator circuit from Q2 base to ground. In the v6.0 that had to be connected on the bottom of the PCB, appears the change to v6.1 is that it was then included on the PCB layout.

      I do have Tony's original build notes for the v6.0 RX, so if you want a copy of those, drop me an email directly so I can forward them on to you.
