Thanks for the FM report. I just realized I never posted the one I did. I added it to post #3 and here:

I got it pretty close; WFFM 0.4 mi at 154°. Either way, it's too strong to ignore.
WFFM on 105.7 MHz has a signal power of -3.3 dBm
WBJY on 89.3 MHz has a signal power of -16.1 dBm
The Antennas Direct FM filter has an attenuation of about 20 dB for WFFM and about 25 dB for WBJY.

sometimes two in series are required.
If you use solution Number 1, put the FM filter between the VHF antenna and the UVSJ.
If you use Solution Number 2, it should go between the dipole and the VHF Kit combiner if it is separate. Some VHF kits have an integrated combiner so the FM filter will need to go just before the 7778 input. If you use the 7778, try it without the FM filter first with the 7778 internal FM filter set to IN which is its default position.
