clues. so you're still on that project.

Well, it's *related* to "that" project, yes.

tweak the sensitivity and get a peak at S9 on the CB radio type signal
meter I'm using for this purpose.

! Adjust the meter to get the answer you want. Ok.

Yes! I'm only interested in *relative* field strength. That's why I
asked for a "ballpark figure" to be plucked from the air. I think you
may be thinking of some fancy type of instrument like some guy
mentioned he had that cost 1500 bux.

'twas me talking to someone else.

These ham-type jobs I'm
interested in cost just pennies to make as they don't need any
absolute standard of accuracy; only a relative indication. You tweak
the meter's sensitivity control to show antenna A of the TX giving
rise to say S5 on the meter. You then change to antenna B and see if
the reading is any higher or lower. It's really as simple as that.

Yup. gave you the eqs to figure out your ballpark figure. I figured
a ballpark figure might work if you gould figure out how much
voltage appeared at your RFSM antenna. had I known you had a
reference transmitter i might have suggested checking your RFSM
reading at one location with the ref and another closer location
with the test Tx, identical readings indicating sucess or close to
it.

I'll use a distance of 6m.

Noted, thanks.
