While most of the communications remain on VHF, there have been a few reports of activity on HF as well. Several people have reported hearing phone patches and fishermen discussing the BP oil spill on 8650 USB.
Another frequency to keep plugged in is 5320 USB. This is used by the US Coast Guard and was quite active last night and this morning. Reception here in California wasn’t all that great, but I did manage to snag a little audio.Listen to audio clip
