Feed Notes

Currently, I am only scanning channels 9, 10, 13, 16, 1021 the old 21A, 1022 the old 22A, 1023 the old 23A, 1082 the old 82A

Milwaukee has the most traffic in the summer months. Though some commercial traffic does happen throughout the year.

Feed will strictly keep to the U.S. Marine Band VHF voice channels both for recreational, and commercial shipping.

Right now this is one feed that scans. Meaning some traffic may be missed if more than one channel is transmitted at a time. In the future, I hope to have two feeds to be able to separate out channels 16, and 9 from the rest of the channels. I am using an ultra-low-cost computer and a software-defined radio.

Here is some general info on what each marine channel is for  ( * ) denotes I am scanning it on that channel.

Note: VDSMS (VHF Digital Small Message Services). Transmissions of short digital messages in accordance with RTCM Standard 12301.1 is allowed.

Frequencies are in MHz. Modulation is 16KF3E or 16KG3E.

Note that the four digit channel number beginning with the digits "10" indicates simplex use of the ship station transmit side of what had been an international duplex channel.  These new channel numbers, now recognized internationally, were previously designated in the US by the two digit channel number ending with the letter "A".  That is, the international channel 1005 has been designated in the US by channel 05A, and the US Coast Guard channel 1022 has been designated in the US as channel 22A.  Four digit channels beginning with "20", sometimes shown by the two-digit channel number ending with the letter "B", indicates simplex use of the coast station transmit side of what normally was an international duplex channel. The U.S. does not currently use "B" or "20NN" channels in the VHF maritime band. Some VHF transceivers are equipped with an "International - U.S." switch to avoid conflicting use of these channels.  See ITU Radio Regulation Appendix 18 and ITU-R M.1084-5 Annex 4, summarized here.

These new channel numbers should eventually begin to be displayed on new models of VHF marine radios.

Boaters should normally use channels listed as Non-Commercial. Channel 16 is used for calling other stations or for distress alerting. Channel 13 should be used to contact a ship when there is danger of collision. All ships of length 20m or greater are required to guard VHF channel 13, in addition to VHF channel 16, when operating within U.S. territorial waters. Users may be fined by the FCC for improper use of these channels. See Marine Radio Watch Requirements for further information.
