You are talking about 1355 programmed frequencies. I don't know of an exact list, as most use the User Frequencies that were preprogrammed by ICOM. The remaining memory channels are broken down by the frequency range that they serve. For example, memory channels that start with a 4 are associated with the 4 MHz frequencies. A summary is in your user manual, page ii of the Guick Reference. I have a complete list of frequencies put out by the Coast Guard, but it won't help you with the assigned memory channel. I can see if I can find the website again, or send you a copy. It is on the boat, and I won't be down there until Wednesday night.
BTW, check the CHU-7 frequency (#19). That one was changed a while back, and some of the memory channels have not been updated. Gary's list on Dockside Radio has the correct frequency.
