Can anyone help with a copy of the internal wiring of this Meter?

I disposed of mine recently, but didn't copy the circuit!

I can get that for you Jim, since I was the one that bought it

Try this article by Gerry O'Hara on our Eddystone User Group website. The circuit is on page 8

Thanks Mike, I've now got the circuit from the site suggested by Chris.

I don't think the original meter you now have includes the 200ohm resistor or the switch shown in the circuit diagram, could you confirm this pse.

Regards,

Jim

Hi Jim,

No the meter is entirely original as it should be and as per the diagram less the 200r switched resistor. As it says in the article the switched 200 ohm resistor is suggested to be fitted to stop the end stopping of the meter which occurs on very strong signals. The eddystone is set for 4db per S point rather than the modern 6db per point.
