[hpsdr] Mercury: Selection of frequency Segments

[Ahti Aintila]

Bob,

You are almost right, you should be shot, but not alone. We all, the
whole SDR gang, should be shot for playing with the quadrature
sampling mixers and the PowerSDR spaghetti such a long time instead of
concentrating our efforts fully to the direct digital downconversion
and upconversion methods. :-)

Kudos to Phil, Phil et al., shame on us, the lurkers!

73 and Better New Year 2009,
Ahti OH2RZ
