Got to learn how to use that database LOL. If you have a rooftop then these are the frequencies you should monitor for the Delaware River and Philly. The port of Philadelphia is channel 14... Most of these are Coast Guard frequencies or Port frequencies and here we go. CG 121, CG 409, Channel 6, Channel 9, channel 12, Channel 13 all boats must monitor Channel 13 and channel 16 on the river. All of the lift Bridges operate on channel 13, Channel 16, channel 22, Channel 81 and Coast Guard auxiliary is channel 83 out of Bordentown. There you go.
I guess what threw me was the reference to San Francisco Bay on Channel 14.
It is difficult learning frequencies, it took me a few moments to write that post, it's all in my head, I've been listening to marine radio for 55 + years. The only thing really new is the conventional digital VHF and UHF channels with a standard NAC of 296. These are all national frequencies, it just depends on what a locality uses of those National frequencies, for example, if you're up on Long Island I would have added Channel 21 and 23 for the Coast Guard, they don't use it down here. If you were not on a river I would not include Channel 13 but that is the most important channel on the Delaware River. Keep plugging away, you'll get it.
