[VHFcontesting] transverter modification

[Zack Widup]

You might be better off building the Paul Wade 222 MHz transverter from
scratch.  Although it was originally designed to work with the FT-817,
there's no reason you couldn't use it with any rig if you adjust the power
to the transverter correctly.
