MHFD has some patch running between their VHF radios and GCRCN. A week or two ago their radio service was out there testing some sort of station pagers on the system. Since then they seem to have a squelch issue or some interference issue getting in to the system. Sounds horrible, and it is tying up both a channel in GCRCN but the same noise is going out over on 154.31 when it occurs.
