You are correct Eric. Did put a pig tail on just to see what it would do. 100 watts of spurs and other messy junk. I was thinking of building a filter that could go between the exciter and the PA. Not sure how that would work out tho.
Its looking like I have a UHF MSR2000 that is useless at this point. Unless I can find a low spit exciter in hopes that FL101 will tune up. There is a Moto rep in town. Going to look into maybe getting a new filter that will work, and replacing it. Not to many options at this point. --- In [email protected], "Eric Lemmon" <wb6...@...> wrote: > > Jason, > > You definitely should not bypass FL101, because it performs an important > function.
