With my second floor shack, I have common mode RF issues that have been
well mitigated with common mode chokes of 5 FT240-43 cores, but at 40
and below frequencies the choking could be improved. I ordered several
FT240-31 mix cores and was going to replace the 43 mix, but thought I
might have good luck if I just added the 31 mix with the 43 mix, i.e. 10
ferrite cores in a choke as opposed to five. Are there any
disadvantages to this or perhaps is it overkill?
