[TenTec] confusion about 563 vs 564

[Ron Pletter]

I have been off this reflector for more than a year and recently
resubscribed.  At one time I owned an Omni VI model 563.  I presently own an
Omni VI Plus model 564.

But I am finding folks posting to the list model 563 which was upgraded to
option 3, and are calling it an Omni VI Plus.  Even the used/demo list from
TenTec uses the teminology "Omni-VI factory upgraded to Omni-VI Plus" for a
model 563.

So my question is:  Is a model 563 with Option 3 upgrade now called Omni-VI
Plus?  Or is the term being used loosely?

Thanks and 73
