Stereo-CW Revisited (Yet Again)

It would SEEM that the topic of STEREO Cw (or even Stereo-anything in amateur radio) keeps coming up in the varied radiosport activities I engage in.  While distantly different, running a radio remote from Ramona or Anza (both in So. California), or running the FT-2000 locally (in Concord),
the audio output of ALL these devices end up connected to the SAME switch panel, and eventually find their way to the pair of Autek QF-1 a filters, which create the "Stereo Radio" effect.

The audio frequency "direction of movement" (low-to-high or high-to-low) can be reversed/altered
in 2 different ways:

• Switch between sidebands (Lower / Upper) on the transceiver.
• Set the audio filter frequency different for each ear (Ex.: Low on left - High on right)

Spend an afternoon tuning around the Cw bands and notice how the different audio filter frequency settings affect the direction and rapidity of tuning through Cw signals.  Then again, next time you are running a frequency, pay attention to how the stations spread out AROUND your listening experience, depending upon their offset from your run frequency.

If need be, you can use the RiT/Clarifier control on your transceiver to shift the station you are working to a different "position" in the received passband.  With logging software like N1MM+ you can declare the F3 ("TU") key macro to "CLEARRIT" after each contact, returning the receive passband back to your original settings.

Because the QF-1A filters ALSO come with an auxiliary notch filter, you can remove offending
carriers (or other junk) as needed; something the digital notch filters can do w/o also eliminating
the Cw signals themselves.

Additionally, several filters can be series-cascaded to provide any additional filtering needed.   
I have accomplished this by way of MFJ-752 & MFJ-784 filters (for the left ear) along with JPS
NIR-10 & NIR-12 filters (for the right ear).  Because any of these filters can be switched out-of-line, virtually any combination filtering and Stereo-Cw effects can be created to enhance the listening experience.  I wrote more about this in September-2021 ([CLICK HERE] to read that).

Cw has been with us for over 100 years.  Stereo-Cw brings us a 21st century solution to a 20th century problem.  Have YOU ever played around with Stereo-Cw?  If NoT, you're missing out.
