Wade, it sounds like you've got yourself a fine balun (perhaps).
"Triple Cores"...the statement is meaningless unless you say which cores you
use. I'm confident you used the right one, but finish the sentence and
state exactly which core you used.
The balun in the 989C is not particularly good. It's OK but marginal.
The newer MFJ 9982 uses 4x 2.4" cores which IMHO is about right.
According to Jim (K9YC), you might even need 5 cores in some cases when
running legal limit power.
In any case, your choice of the 1:1 instead of 4:1 was spot on! Good job.
The vendors have been misleading people here for far too many years.

Subject: Re: [TenTec] which balun?
Mine is a Homebrew Triple Core in a 1:1 Current Configuration. It makes the
Balun in the back of my MFJ-989C look small. I use it on the 10 foot piece
of RG-213 between my Window Line 450 Ohm and the Tuner. I can't get the
Window/Ladder Line through the window in a practical manner. It is housed in
a Commercial Electrical Enclosure. You may not need so much. I wanted the
ability to run Full Legal Limit with no worries.
