I have acquired an ICOM700 SSBwith the purchase of boat.

Now what is it?
How do you work it? Any instruction booklet out there?
What licences are required both boat and operator?

I thought I would keep it simple at the start.

It's a short wave transmitter. You must have a licence to operate it - the Long Range Certificate if UK based. That takes a 4-day course normally, at the end of which you'll know everything you need to work it.

If you're not planning any long distance trips you might as well sell it as it's not a lot of use in home waters! (IMHO).

Methinks a slight slip of the pen here. SSB is an HF set which is actually long(ish) wave.

Receive 1.6MHz - 23.9999MHz
Transmit
roughly the same numbers but with a few gaps.
Icom usa seem to have removed it from their listed handbooks, but if you pm me your email address, I will send you a copy of the handbook.

An excellent retired radio there, worth its weight in gold if you are in remote areas, not so much use if you stay inshore except for loch and fjord type areas where the line of sight VHF doesn't work too well.

An instruction manual is available at icom uk.

The LRC licence is not too hard to study for if you know the stuff for the SRC already.

The radio came in many versions for different countries, and it needs the suffix UK to be type approved for the UK. It needs an antenna tuner unit, which is usually a grey box AT120 at the bottom of the aerial or in the lazarette and often any problem with the radio can be traced back to the wiring between this tuner and the radio, rather than the radio itself.

Hope you enjoy the new boat.

If you have a laptop you can receive weatherfax and weather telex RTTY information FREE by downloading demo/free software from the internet. All you need is a simple lead from the external speaker socket of the Icom to the mic connection on the laptop. Do a search of weatherfac if you are interested or ask again for more details.

It certainly is less use inshore than offshore but you can receive MF broadcasts from the CG which can be useful if you are out of range of them on VHF. For example when we were in Trebeurden in N Brittany and wanting to head for Guernsey but had an iffy do we don't we forecast from French sources we were able to add Jersey Radio weather information into the equation which was more specific on timings of the arrival of strong winds. We could receive Jersey on MF but not on VHF.

I have certainly always considered HF & shortwave (SW) as the same thing and that is the normal convention.

VHF would I suppose be VSW although I have never heard the term.

I guess it comes down to how long is long and how high is high.

It should be much more gap than not, unless it is modified ('opened-up') in which case you need to be rather careful with it to avoid intruding into freqs which will make you very unpopular.

I've always taken the ranges to be roughly
VLF 3- 30 kHz
Longwave/LF 30 - 300kHz
Mediumwave/MF 300kHz to 3 MHz
Shortwave/HF 3Mhz to 30Mhz
VHF 30Mhz to 300Mhz
UHF 300Mhz - 3GHz
SHF 3Ghz- 30Ghz

The exact point where one range begins and another starts does vary depending on who you ask

No error. Roughly speaking, Longwave is 100-500 KHz, Medium 500 KHz - 1.6 MHz and Shortwave 1.6 - 22 MHz.

SSB sets can in some cases get down as far as 198 KHz but generally operate in the 2-22 MHz bands which are very much the Shortwave territory.

Not to be confused with VHF which, at 88-106 MHz, is a much shorter wavelength but outside the range known as Shortwave.
