Malcolm,
Yes, my intent is to rectify the AC output and feed it to the meter. One
problem is that I don't have any idea what the output voltage is and
whether or not I might get dropouts, if the level drops lower than the
forward voltage drop of the diode(s). I am assuming that since the output
has to drive the LED, it is high enough.
My problem is that trying to judge the output level by the relative
brightness of the bipolar LED is not a very good option for me because of
my extremely poor vision. I'm not sure that I will be able to do this at
all. I was hoping that I could use a very simple rectification because I'm
not looking for any particular accuracy. I just want to use the meter to
indicate the signal strength as it fluctuates so that I can find the
maximum point. If this is all I am doing, can I just use a Schottky diode
as a half-wave rectifier and feed this to the meter? The problem here is I
will compound any problem I might have with a low signal level, cutting it
in half with the rectifier. I think what I'll do now is just start trying
things. I have nearly completed the tuner itself. I only need to solder
the connections to the LED and I'm through. I will try the half wave
rectification with a Schottky diode first and see what I get and go from
there. Thanks.
Paul
