[TenTec] Omni VI Output Spike

[Robert & Linda McGraw K4TAX]

Just got another Omni VI Plus and noticed that when it used with the Centurion amp in QSK mode that there is an output spike generated on key-up in SSB mode.  I seem to recall reading something about this.  Anybody recall what this is caused by and how it is corrected?  Would appreciate any info you may have or recall.

Will save me a bunch of huntin' and pokin' if you recall such and it will be greatly appreciated. 

Thanks in advance.
