I've seen digital panel meters like these for some time now:
3.5 DIGIT LCD PANEL METER, 0.2V SCALE
3.5 DIGIT LCD PANEL METER, 0.2V SCALE | AllElectronics.com
3.5 DIGIT LED PANEL METER, 200 MV
3.5 DIGIT LED PANEL METER, 200 MV | AllElectronics.com
I thought these might help me with my need for a RF Wattmeter for my HAM Radio shack. I though I'd place the transmitted RF across a 50Ω non-inductive resistor, then rectify the voltage across the resistors and apply it to the meter.
The schematic below shos the plan. Before I ordered parts I thought I put it put here to get comments to see if I've missed anything.
Any thoughts?
thanks
