[TenTec] Sweep on O2

It's true that the sweep may not meet everyone's operating needs.  It's
better than it has been previously, and is certainly more than adequate for
my use.

As I indicated in a post last night, I found the SNR -- actually (S+N)/N --
ratio to be improved by at least 10-12dB under VERY difficult noise
conditions when using NR.  I was actually quite surprised at that result.

On 20M this morning, with very differenct noise conditions than last night I
measuredthe SNR increase to be on the order of 20dB.  It was less at very
narrow CW bandwidths, but that's to be expected since there's less noise to
begin with -- the narrow bandwidth itself improves NSR ratio.  At a setting
of NR = 1 I measured about 10dB improvement, and at a setting of NR = 9 I
measured about 20dB overall using bandwidths of 1Khz and greater.

Everyone has to make up there own mind whether that constitutes "broken", I
guess.
