QSL Gene? and Info

Where are you in Marathon Gene, and what kind of sked do you maintain on HF? Two books with some of the info you need are: Mariners Guide to Single Sideband by Fred Graves-- has all of the SSB channel frequencies, including the duplexes. It's published by SEA Datamarine. Cruiser's Radio Guide by Roger Krautkremer (rogerk0yy@aol.com-- has most of them. It's published by FMS Services A search on Google or a book site should help you to locate both of them.

Legal concerns

Be aware that the FCC does not permit ham radios to be used for transmissions on marine hf. They must be certified for marine use. It is legal to transmit with a marine radio on the ham bands if it has the freq converage If your receiving only then there are no restrictions

SSB / Ham

You probably know this, but in case you may not, many boats use what is called a Marine Single-Sideband (SSB) radio. Like a Ham radio, it is High-Frequency. In fact, an HF Ham rig is a sub-species of SSB. Like Ham, Marine SSB has its regulations and its frequencies. Many of them are referred to as channels, but the designations are related to the frequency rather than the wave length. Thus, there is never reference to 10 or 20 meters, for example, but to 4 megs, 6 megs, etc. The type of traffic ( I am referring to distance and propagation ) that is done on 20 meters in Ham radio, will typically be done on 12 megs with Marine SSB. Some rigs are legal for both Ham and Marine SSB, but many are not. A typical Ham rig is not, although its capability (but not legality) can be expanded by clipping a single wire! Many SSB rigs lack the ability to tune to a frequency, rather than a channel, so you can get stuck there, too. But, there are plenty of rigs that will do both, in which case you want to make sure you have one that can be tuned with a dial, rather than numeric entry, since you may be changing frequencies to find an open one. By the way, the FCC does, in fact, monitor SSB transmissions, and can tell if a Ham rig is slightly off frequency, which it often is. It is legal to listen to Ham with a Marine SSB, and to transmit in the case of emergency. I am sure those reccommended books will give you much more to chew on. Good Luck. Tim (XE2-KC6-GIT)

amateur HF marine nets?

Can anyone post times and frequencies of marine nets (if any)on the amateur HF bands? Thanks

There are many web sites listing marine net frequencies and other related information. I have a little secret: I type in www.google.com which is an excellent search engine, then type in what I am looking for. In this case, I came up with one that looks pretty interesting, and is listed at the related link below. You may also visit my web site for other sailing news on Lake Ontario.

Marine HF nets

There are numerous nets, although if you are in Chicago you will probably be limited to the ones that operate on 20 meters. The Maritime Mobile Net, or a derivative therof, is passed around the world, usually on 14.300 or 14.313. In the Pacific, this takes the form of the Pacific Seafarers Net, which is on 14.313. In addition to the normal chit-chat, boats call in their positions and weather as part of a regular roll call, so it is pretty interesting, particularly if you know someone. I imagine there is a version of this operating a bit earlier in the day for the Atlantic and the Caribbean. There are a few other twenty meter nets and literally dozens of forty and eighty meter nets. Downwind Marine, "cruiser central" in San Diego, used to keep a very thorough list of nets from all over the world. I think they have a website at www.downwindmarine.com, but I am not sure. Anyway, they are in the San Diego phone book.
