MIMCO 2273A Marine Radio - UK Vintage Radio Repair and Restoration Discussion Forum

Callum Ives · 2nd Mar 2016, 5:46 pm

Hi - I've inherited my dad's vintage radio collection which I will hopefully get round to cataloguing/testing etc soon.
One radio I'm interested in getting going is a MIMCO (Marconi International Marine Radio Co.) Model:2273A. With a view to installing it on my boat.

Does anybody know anything about this model and how to connect an antenna to it? presumably a standard AM/FM antenna will work? It is in excellent condition so hopefully will work. There are a couple of other Marine radios in the collection that I will check out soon too.

Any advice gratefully received, thanks Cal

From what I can see it's roughly the same as the Eddystone 670A.

For this you'll need what is essentially a "long wire" antenna - a wire up into the rigging, supported on insulators - *or* a freestanding whip-antenna - something like this: http://www.cactusnav.com/section-fib...a-p-12360.html

*BE AWARE* that this radio is an AC/DC design - if maintained and installed correctly it should be safe but incorrect installation and aged components (which it is bound to have, now being 50-odd years old) can be an electric-shock risk. Before considering any installation you should have the radio checked-over by a competent service technician who should be expected to replace the aged safety-related components [several capacitors] with modern ones. The resistors in these radios also drift in value and many will need replacing if it is to perform to original specification.
