I recently put up an Imax2000. I'm getting a weird sounding signal on 27.190mhz that is wiping out my receive on ch.19. The noise wasn't present on my old sirio gpe27/5/8 wave. It wasn't present on the wilson 1000 in the mobile either. Another oddity is my imax picks up the wx stations beautifully, where the sirio didn't hear any weather stations,not even faintly?! Has anyone else experienced something like this?
