Used to be real common from lightning hits.

Hmm, I didn't see one. It does have a multi input with coax and 300 ohm twinleads, and there's a ceramic cap across the 300 ohm terminal. I wasn't using the 300 ohm input, but I tried swapping the capacitor out anyway, and when I removed the cap the ghosting on the RF input went away entirely. Despite not using that input, it appears it is somehow connected to the same circuit (I'm not entirely sure then what the 300/75 switch does if it's still in circuit).

I'm debating soldering in a new capacitor or just leaving it out since I don't use twin leads on VHF anyway.
