Satellite Doppler Correction HRD vs. PST Rotator Video
All:
I recorded a short video that compares Doppler correction between HRD and PST Rotator. It would appear that even the finest tuning steps in PST Rotator are too coarse for CW.
I believe I have it set for the best results, but I could be missing something?
Any sugestions?

You won't like my answer. :)
The brain is a powerful computer (my teacher called it a DSP). Just focus on the cw and ignore the tonal shift. Do that for a few QSOs and there will be a point you won't notice. Try not to get frustrated that it is happening.

I've been using CW as my primary mode for more than 30 years so I agree with you. On the other hand, the comparison shows what can be achieved.
