I wanted to build an RF relative field strength meter, I've allowed for 0.25mV
input to give rise to FSD on the microammeter.
Question being, however, is that going to be sensitive enough?
Does
anyone have any idea what the field strength in microvolts or
millivolts is from a half Watt transmitter at about 6 feet away?


Figuring the field strenth of a .5 W xmtr at 6 feet is difficult. Depends on
the antennas on the xmtr and the FSM and their polarization. Also, depends on
the sensisitivty of your FSM (field strength doesn't depend on sensisitivty but
your reading will).
Since this is a *relative FSM* I would get something working, use that as a
reference, and go from there.
