To answer the SSB question. Here is a picture of both rigs listening to band
noise on 80 meters without the NR turned on and with the bandwidth at 1.8
khz.
Notice how the Omni VI's pattern is elevated off the bottom of the chart.
This demonstrates the lack of low frequency response of the TenTec filters.
Note the noise spikes kick up to about 3.5 khz on the Omni but nearly 4.5
khz on the PRO.
The main thing to note here is the density of the noise. The PRO's pattern
is almost solid blue while the Omni's is much less intense. Also look at the
top pattern. The PRO III's signal is significantly more intense.
Obviously, the Omni VI is going to be much easier on the ears under these
conditions. Those big noise spikes come out sounding like clicks on the PRO
but are hardly noticeable on the Omni.
Keep in mind....My PRO III is being checked out. It could be defective. The
jury is still out on this one.

Hi Steve, the Pics are very interesting, and I will follow your saga.
However, being a
98% SSB op that rarely if ever gets narrower than 1.8 in rough conditions
(too much loss of fidelity at narrower bandwidths for me), is a
measurement at
250Hz CW bandwidth going to be something I notice at 1.8 - 2.9khz
settings?
As I said, nothings happening until the QST, and hopefully a Sherwood Eng.
review.
