R820T internal filter or IF frequency settings affecting tuned signals

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Center tune to one of the stronger NOAA frequencies, like Syracuse: 162.55.
2. Tune that frequency up/down toward the outer ends of the spectral display 
and watch the signal appear toward the ends, and disappear as it's tuned back 
toward center.

What is the expected output? What do you see instead?

Expect the signal to have equal signal strength across the spectrum.  It 
appears that one of the internal filter settings or the tuned IF frequency on 
the R820T is causing the signal to be filtered out as it is tuned toward the 
middle of the spectrum.

Note: This may be unique to the fringes of the defined frequency bands.  Check 
to see if using one of the higher/lower bands affects the filtering of the 
signal and allows the frequencies in the 162.xx range to be received.

Resolved with #161 commit.  Code was not correctly setting the frequency 
divider, integral and sigma-delta modulator registers resulting in critical 
discontinuities in tuning and effectively only tuning half of the frequencies 
correctly.
