" G'day all, just an update. Although the hybrid balun effected a great
improvement, there was still a 'trace' of breakthrough so I tried
another approach to see if I could obtain any further improvement....and
I did! I used possibly the oldest technique around that of a wire
quarter wave (and unconnected at the distant end) counterpoise cut for
40 m, the only really affected band. All breakthrough is now gone and
all other bands are clean! Regards, Felix vk4fuq."
So you completely fixed the problem with a quarter wave counter poise.
Now we don't know if your hybrid balun was even needed.
