Craig, the Orion's audio is the most pleasant I've ever heard on
CW, surpassing my previous gold standard, the Kenwood TS-930S. Even
Orion's 100 Hz DSP filter is very pleasant to use because Orion
automatically widens the DSP shape factor as BW is reduced. You must
have been listening to a very narrow filter with sharp skirts on your
Pro, but you CANNOT make an Orion sound bad on CW even if you use the
narrowest filter settings.
I am a musically-inclined person, season symphony ticket holder,
played the Viola in HS orchestra, have a very good sense of pitch and
am sensitive to tone distortion. I will tell you that listening to CW
on the Orion is truly music to my ears.
The contrast to an MP (which I used for 6.5 years previously) is
like night and day. I almost NEVER used the MP's DSP because it sounded
so bad, and now I routinely use the 110 Hz DSP in the Orion. I HATED
having to zero-beat with the MP because the Spot tone had so much
distortion (must have been a square wave). It was truly difficult to
zero-beat because I was never sure which of the multiple harmonics I was
hearing was the fundamental. With Orion I can zero-beat to the exact Hz
because the Spot tone is so pure. I do hope Ten-Tec will extend the
Spot range to 200 Hz and then it will be better than my trusty TS-930S
in every respect (because I like to use very low tones for weak signal
DX-ing on the low bands).
If good CW audio is your thing, you will love Orion.
73, Bill W4ZV
