Background noise - no squelch between transmissions

[wb1f]

I have a new feed - Melrose Police & Fire. I am noticing there is constant digital-infused background noise at all times between transmissions on my port, as if my squelch is open. I do not hear it on other channels. It is not coming from the scanner, and the computer is outputing clean audio at the speakers. So it seems to be inserting on the server end. I am searching the forums for info on this. Any info would be appreciated, perhaps the admins may want to redirect my stream to a clean port. If so, just do it and let me know, I will catch up. No problem if my feed gets cut-off during the transition.

Thanks all!
