Replaced Q2 twice and got .5v on 8R both times before concluding
something had to be shorting 8R to ground. Found a little filament of
untrimmed toroid wire making a bridge, trimmed it, now we're though the
alignment and receiving 40m signals just fine.
One thing though...I'm certain I heard somebody here on the list
recently who had louder signals with the preamp *off*. And I'm pretty
sure Don told him what the likely reason was.
I just can't find the thread....anybody remeber? Don?
73 de Maggie K3XS, who will spare the "Now that we know" thread a
recital of her 30-yr computing career. ;-)
