I need some help figuring out a problem with a scanalizer.
The signals on the left side of the screen are large, but as you tune
them into the center of the screen so you can hear them on the rcvr they
all but disappear, going from say 2 inches tall to about 1/4 of an inch,
then when you tune by them they get bigger on the right side of the
screen but not as big as on the left. I see no grass at the bottom of the
screen, the signals just come up out of a flat trace. I went through the
alignment in the book but that was right on. I am using a Drake 2B rcvr
and the coupling cap is the size and connection recommended in the book.
The rcvr is as hot as the one in my Atlas so I know its not rcvr sens.
I'm contemplating changing the if amp in the scope but would like a
little input first.
Is this close to how they worked, this I doubt, or am I just accustom to
the Tektronix pan adapters. Any help would be appreciated because I've
never seen a heath scanalizer work.
Thank you
