Charity Floyd is presenting: Moving coil s meter, qrp howes amateur ham radio
Here we have an unused moving coil meter having a full scale deflection (FSD) in the region of 200 uA (micro amps). The top scale could be used for indicating 'S' units on receive, and the lower scale to show transmit power.
The face of the meter measures 40 x 40 mm, and the overall depth is about 25 mm. The scale could be backlit by providing a source of light behind the meter - but be careful not to 'cook' the meter if using a filament bulb!
