I beg to differ with you on this one.  When I compared the non QSK to QSK
output waveform on my 765 I found the QSK element trailing edges were
chopped off by 8 ms.  I added a capacitor across the 765's FULL BK-IN switch
contacts to enable the VOX long enough to complete each element.  As I
recall the Frankfort radio club published the same fix in their news letter.

Keep up the good work.
