Déjà vu.  

I ran into the exact issue back in '92 when I purchased my Omni Six.  I used
a Nye Viking low-pass TVI filter to eliminate everything received above 30

I traced my source of interference to a couple local TV and FM broadcast
transmitters.  Not sure why the front end was susceptible to strong-signal
VHF, but an internal LPF right at the front of the Rx would have been a
welcome addition.
