Searching the web I was unable to find a diagram for adding an S-meter to the
BC-312 and BC-348.

Clearly I could try typical S-meter circuits, but I wish to keep the receiver as
original as possible, and I would then prefer to directly build a proven
circuit.

The circuit should have a fairly simple interface with the receiver, so that the
meter can be easily put externally,

Thanks and 73

My first serious receiver was a BC-312.... 1952 I think. Except for
the lack of band-spread it's a great receiver. Here is a link to a
circuit for adding an S-meter. I don't recall how I modified mine,
but this looks good.

Thanks for info. It looks fairly simple and implies a fairly simple and
restorable modification.

I must check whether the same circuit can be used for the BC-348 too.
