To give you an idea what I am seeing I have posted a spectrogram screen shot
with all three filters superimposed on each other. Does it look typical to
you?
It looks fine, although I would move the two wider filters a bit to the right.
There looks like about 6-8 db difference in attenuation between the widest and
narrowest filters, which is probably on the high side of normal (although this
tends to vary). I see about 4 db on mine, which is #709 but has had the
crystals replaced and T7 rewound to current spec.
I would be interested in knowing how much difference in attenuation others are
seeing. I know that K1JD has an ANCIENT K2 (field test vintage) which has zero
db difference!
