WTD Tranceiver for amateur and marine bands!

Well, is there such a thing, and where will I find it?

Alan,
Most modern amateur transceivers can be opened up to cover the whole HF
spectrum on transmit, usually by adding or removing a few links or diodes,
although some makers frown on this. Icom, for instance, say I'd void the
warranty on my IC-746 by doing this. Alternatively, take a look for a
commercial rig like a Harris RF3200, they can do 1.6 to 30 MHz with no gaps
but will also do the ITU marine HF channels by channel number as well.

> Alan,
Although this is quite true, I think that you will find that there is no
"type approval" for a modified amateur tranceiver on the marine bands
(except for emergency use).
OTOH, I understand that the Icom IC701 and IC710 retain their type approval
when "opened up" to marine bands.

One other thing that occurred to me, Alan didn't actually say he's looking
for a HF marine rig but if it's the VHF marine band you're interested in
then a lot of amateur 2m rigs "open" to a typical coverage of 136 to 174 MHz
FM and would cover the marine band. Same caveats apply as for HF re type
approval and maker's warrantees.

Do any of them transmit as well, or are they receive only on Marine
band?

Beware. As I recall it the Marine band channels are
not all simplex and they have funny power ratings
to produce guard bands.

Agreed - or numbered very logically! (Probably results from starting off
at 100KHz spacing or summit.)

Hmm, good point - but I'm only thinking of an HT for the dive-boat...

My IC281H does, not that I've tried it of course :-))

£100-£150 for new with the type approvals. Worth it just so if the
coast guard says *move to 18* you know where to find him. We are
talking life support here not this piffling little ham stuff.
Naturally you need to pass the ATO exam but it's multiple choice
and we are always told how easy they are.

I have an IC-T2 (2m handy) which is opened up and programmed for the
marine band. I can program in all the offsets for each channel too. Not
only that, it has a channel function, so switching the radio on whilst
holding down a key combination sets it to channelised mode where ch16
really is ch16 etc. It stays like this until you repeat the powerup/key
combination to reset it to a frequency display.
Not type approved, but its my backup radio and if it was an emergency,
it wouldn't stop me using it...! :)

It would make good sense to try it (into a dummy load of course). It would
be quite legal under SOLAS to use your IC281H in case of an emergency (a
hazard to the vessel or recently, any person [1]).

[1] this is not the full wording, see the relevant regulations.

Look out for the radio inspector. Do they still have radio
inspectors at ports?
They used to do AR morse tests as a sideline ISTR.
