how long of cable run do you have Steve. I have heard to short of a run on
c band analog can cause the sparkles I think a 150 foot run of cable was recommended.thats what I have and don't notice any sparkles.
also you can try adjusting the freq on the analog channels up or down a few Mhz sometimes that helps.
