[TenTec] Omni VI+ Keying

Could some of these issues be the difference between and Omni VI opt 3 and a 
Omni VI+?  Although the Omni VI with opt 3 installed does have the same 
features as the Omni VI+, from my experience, they aren't the same.  As to 
the exact differences, since I no longer have both, I can't do any 
measurements nor do I recall specifically.  However, I do recall that when I 
acquired the Omni VI+ that it measured different and operated and sounded 
different than the upgraded Omni VI with opt 3.

According to info that I have using the formula  SPEED (WPM) = (DOTS/MIN)/25 
Thus a string of dots that counts 10 dots per second, speed = (10 x 60) / 25 
= 24 WPM.

Comparing dots to dashes, we find that dots should yield about 50% while 
dashes should yield about 75% of the solid carrier mode.  This can be 
influenced to some degree by meter damping.  In the case of a PEP, in either 
case, meter the values should be near 100% of the solid carrier mode.
