I am clueless as to why the CW failed to work AT ALL when USING a balun.
The internals of the balun look fine. Any thoughts?

1. Baluns are designed for a narrow range of *resistive*
impedances, e.g. 50/200 ohms (plus or minus). Over what
range of impedances are you asking your balun to function
properly? Baluns don't handle massive reactance very well.

2. A misapplication example: 300 ohm twinlead with a 10:1
SWR can take the impedance seen by the balun down to 30 ohms.
Then the 4:1 balun tries to take 30 ohms down to 7.5 ohms.
That's a lossy situation for a tuner.
