Stereo Ssb: It's STILL Easier than you Think

For WQ6X, the use of stereo receive audio has revolutionized station operations, especially
when it comes to running radiosport contest events.  While stereo-Cw makes for most stereo
audio processing, I have also found dual-channel audio separation to be effective when running
RTTY contests; and yes, even in Ssb GiGs.  Here is what I have said about it before:

• [X] - Stereo Cw: It's easier than you think
• [X] - Stereo Cw: Advancing the Art of Equalization
• [X] - Stereo RTTY - Is it Possible?
• [X] - Stereo Cw - Enhancing your FAVorite Radio receiver
• [X] - How Stereo-Cw becomes Stereo Ssb
• [X] - Stereo Cw - Learning to Navigate PILE-Ups

Yes, I have found many ways to leverage the stereo audio facility built-in to the Yaesu FT-1000mp, and now this year, the Yaesu FT-2000.  While I have used many different audio filters and DSP units, the Autek QF-1A SSB/Cw AM Filter is in a sense the most versatile of all the filters.  

For the 2022 CQ W.W. Ssb contest, I used a pair of QF-1A's to process the dual-receive audio
from the Yaesu FT-2000 and the remote audio from the K3/0.  As I said in my write-up about the event, the QF-1A's provided notch-filtering and audio shaping that neither the Yaesu or the Elecraft transceivers could match.

With Stereo-Cw, the goal is to have stations arrayed audio-wise around the more-or-less 180-degree (left-to-right) listening experience.  With Stereo Ssb, the goal was to process the audio differently in the left and right ears to make a given voice become readable. 

Bottom-Line: Stereo audio processing can be JUST as useful for Ssb operation as it can be for Cw and RTTY.  And, with devices like the Autek QF-1A's I get more knobs to twiddle, enforcing the illusion that every signal can be copied through all manner of uncomfortable conditions.

Have YOU ever run stereo audio processing in your station operations?

How DiD it work out for YOU?
