-** SCR Date Author Description
-** -------------------------------------------------------------------------
-** 082 03-25-2005 JWS Original multi-tuner support - requires
-** MTxxxx_CNT declarations
-** 096 04-06-2005 DAD Ver 1.11: Fix divide by 0 error if maxH==0.
-** 094 04-06-2005 JWS Ver 1.11 Added uceil and ufloor to get rid
-** of compiler warnings
-** N/A 04-07-2005 DAD Ver 1.13: Merged single- and multi-tuner spur
-** avoidance into a single module.
-** 103 01-31-2005 DAD Ver 1.14: In MT_AddExclZone(), if the range
-** (f_min, f_max) < 0, ignore the entry.
-** 115 03-23-2007 DAD Fix declaration of spur due to truncation
-** errors.
-** 117 03-29-2007 RSK Ver 1.15: Re-wrote to match search order from
-** tuner DLL.
-** 137 06-18-2007 DAD Ver 1.16: Fix possible divide-by-0 error for
-** multi-tuners that have
-** (delta IF1) > (f_out-f_outbw/2).
-** 147 07-27-2007 RSK Ver 1.17: Corrected calculation (-) to (+)
-** Added logic to force f_Center within 1/2 f_Step.
-** 177 S 02-26-2008 RSK Ver 1.18: Corrected calculation using LO1 > MAX/2
-** Type casts added to preserve correct sign.
-** N/A I 06-17-2008 RSK Ver 1.19: Refactoring avoidance of DECT
-** frequencies into MT_ResetExclZones().
-** N/A I 06-20-2008 RSK Ver 1.21: New VERSION number for ver checking.
