When it comes to marine electronics there are not many things that European cruising folk can say we have a better experience of than our North American cousins – but in the area of mobile telephony we certainly lead the world. In terms of reliable coverage, range of devices and functionality of devices. Its only natural that we should carry our mobiles when cruising in coastal waters and occasionally resort to calling the marina using GSM instead of VHF when the marina staff choose to ignore the radio…

If you are my age then you will probably agree that remembering even your school boy electronics theory can be quite a challenge.
I would recommend that you click on the link in the right hand nav bar called TB Training. This is a link for the training courses that Tony Brooks provides – Tony is obviously “old school” and knows his stuff. If the symbols below have you scratching your head….then click here for a handy reference guide.
For example, here is Tony’s description for symbols of diodes – we all know that electricity

I must admit my attention starts to wane when I read marine electronics books or even long articles on battery systems – and yet short articles and instant advice on bulletin boards and forums leaves you suspicious that some vital piece of info has been left out…
But getting the charging system, and choice of battery and alternator is vital for a modern cruising yacht with so much reliance being placed on sophisticated electronics.
Apart from the numerous postings here on this blog I think you would find the following site at Smart Gauge very informative and well

This new handheld MR HH425LI VHF from Cobra looks very interesting especially if you live in North America or Canada and need to use GMRS as well as a marine VHF. GMRS and FRS are for personal and family use in the USA and Canada. FRS is normally a 0.5W transmission by the way, and requires no FCC license – but this unit will require a license because it is capable of transmitting up to 5W.
But for all of us poor saps that live in the UK, I like
