Yep and likely he had a bunch of external processing and EQ equipment as
well.
I hate to say it folks but we are using a communication audio range which is
typically comprising a frequency response between 200 Hz to 2500 Hz out of
the entire audio spectrum That range is defined by the filter, be it
hardware or DSP, that is part of the SSB generator.
Trying to cram wide band audio through a filter of this bandwidth is like
trying to push a bumble bee through a drinking straw. Nothing nice is going
to come out the other end. Just like I tell the kid in the band, it's easy
to be loud, just buy another amp and crank it to the max. Now being good,
well that takes skill, knowledge and talent.
Now lets try to get the best quality out of the 200 Hz to 2500 Hz spectrum
of audio that's available. It is a lot more of a challenge than buying and
using some external processing and EQ and broadcast type mikes.

I was talking to a fellow Ham on 80/75 meters the other night and I noticed
his audio just didn't seem right. He was running a TS-950s, and a Henry amp
and talking into a D104. I turned my Softrock Ensemble II on and looked at
his transmit signal. Goodness... the bottom end extended another 1 Khz down
the band (KC for others... hi)!!!
I have to give Ten-Tec credit, when I looked at my Eagle's transmit signal
for SSB, it looked pretty dang good. Much better than some new brand Y, and
others I've seen on the air.
I do hope we give up on the 12 V power supply concept much like the auto
industry did with 6 volt systems in autos. It's time for us to move up in
voltage and embrace it. It'll open up a small market for someone to build
devices to combine and balance our existing 12 volt supplies for a 24 volt
feed to our transmitters. Or heck, why not 50 volts...?!?!

How about we all get focused on the broadband noise that all modern
transmitters these days generate, some less so, some more so, and some are
really culprits. Now that's a technical discussion that might someday lead
to improving our hobby!
