2. Are there auxiliary news on HF, or just VHF? As I mentioned before I
hold an amateur extra class license, so taking part in HF nets is not a
major problem.

It's my understanding that cross band communications between Amateur
Radio stations (non-type accepted) and Marine (type accepted) stations
is not allowed.

Well not exactly true. A Licenced Amateur may use any Marine Radio to
transmit on Part 97 frequencies that his License allows. Modifying a
Marine Radio to transmit on frequencies outside those allowed under
Part 80, may, or may not, violate the Type Acceptance for that Radio,
depending on just what is done to the radio to open it up. Radios
such as the SEA MF/HF Marine models, that have a "Test Mode" that is
not documented in the User Manual, but is documented for Service Tech's,
and can be activated from the Front Panel, without any modifacation
to the circuits, under the covers, would be legal to use on Ham Bands,
by Licensed Amateur Radio Operators. If one has to take the covers off

just a followup note here.....ANY Marine Radio would be Legal to use
on the Ham Bands.... The question here is, if the radio was "Modified"
in some way, would that modification, violate the "Type Acceptance" , and
thus make the modified radio not Legal, to use on the Marine Bands......

the radio and cut a diode or solder bridge a trace, this would violate
the Type Acceptance of the radio and isn't allowed, EXCEPT if it is done
by the OEM, at the Factory.

Non-Type Accepted equipment may NOT be used on Part 80 Frequencies,
EXCEPT when Safety of Life or Property Commincations are being passed.



In an emergency, any means of communications is allowed.

Is this not correct?

Only an Advanced Class. To lazy to pass the test again. Couldn't do the
20 wpm part.

Bruce in alaska also an Advanced Class, for many, many, years.....

I don't believe the Marine SSB frequencies (Channels) fall within the
approved Amateur bands.
Any modification of a type accepted radio voids it's certificate and
can no longer be used on the Marine SSB Channels.

Can you even modify an Amateur radio to "Transmit" on the Marine
Channels? My Icom can't transmit on Marine SSB Channels, but I can
receive them.

I believe the older Marine radios operated under crystal control. I
don't know about the new Marine SSB's.

Icom and others make dual use radios, Amateur Radio and Marine SSB.

Wasn't the original question/statement that he was going to use his
Amateur radio to join in on the Marine SSB nets?

Maybe I missed something.

Very easily. My 650 watt mobile (Yaesu FT-900 into a Tentec Hercules II
linear) will run on any frequency from 1.5-30 Mhz. The...er, ah....2KW
Yaesu FT-990 and homebrew beast has the same range in all modes....(c;

It's as simple as pressing a few buttons when turning it on or removing a
jumper wire on the main board.....
