I've got an old Aiwa Reciever, probably dates back to the 70s or
early 80s - massive heavy aluminium front, needle tuner etc. Anyway,
it's got a rather strange connector on the back for the antenna - 3
holes in a row marked "FM Aerial". Any ideas on what I should be
hooking up to it?

A FM aerial? :-)

I suppose it might be a combined 75 ohm/300 ohm connector. Try your
FM downlead into any pair of holes, see which work best! I suppose
it might be worth looking for a voltage on any of the holes first,
just in case it's some special arrangement for e.g. powering a
mast-head amplifier.

My guess is that the outer two are for a 300 ohm balanced downlead
with the centre pin being ground. If so, then either connect a
balanced lead to the outer two pins, or a coaxial cable to either one
(not both) and the centre pin. It would be as well to check for volts
as Lawrence has suggested.

What's one of them then?
What's one of what?
