Catching the Captain on 6951 AM via the NA5B SDR at a S9 and audio doing good except for some type of high pitch squeal happening. Don't know if it's him causing it or something else. SDR shows 2 signals on the waterfall, 6950 and 6951. ID at 0004 and they are doing a awesome Blue's show! Thanks CMS! Note: Chat says that 6950 could be WMR-Weekend Music Radio.
