[TenTec] 2.059d: BinRx still broken

[Dick Green WC1M]

As in previous V2 releases, BinRx doesn't work in 2.059d. It changes the
audio, producing a sort of "surround sound" effect, but doesn't create any
spatial differentiation between CW signals of different pitch.
 
In V1, signals matching the selected sidetone pitch appeared centered
between the headphones, signals lower in pitch were shifted towards the left
headphone and signals higher in pitch were shifted towards the right
headphone (the "spread", or degree of shifting, should have been greater,
but it was useful nonetheless.) In 2.059d, signals of all pitches appear
centered between the headphones. The difference between the two versions is
readily apparent when tuning across a CW signal.
