Searching the web I was unable to find a diagram for adding an S-meter to the

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,

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.
