Kalamazoo Country Fire 154.43 Interference

Has anyone noticed the intermittent Interference on 154.43. I started hearing this Monday afternoon. The interference breaks the Tone Squelch on my radio. Also the signal is wide band. Can be detected from 154.2*-154.4*

Initially I thought it was a birdie on my radio but I tried another and experienced the same.

Does it still do it with the PL programmed?

Yes it did break the squelch even with the PL set. Whatever it was it finally stopped.
