After getting the BFO working I was charged with confidence (again,
only have it dashed, again. A vicious cycle that repeats eternally).
The next part of the alignment concerns the crystal filter.
Previously I got no response to my tuning efforts. I suspected a dead
crystal so last night I took it apart and in the process broke the
holder, ugh! Luckily the material was such that it crazy-glued back
together nicely. I simply rubbed the quartz on it contacts a bit and
put it back together. It seems to work now! Of course this rig will
never throw me a bone.... There are three alignments for the crystal
filter, sharp, medium, and broad, adjusted with variable caps caps.
Only the broad setting responded (peaked) as expected. Ah well, do I
really need a crystal filter? Perhaps the rock is not singing
correctly...
That's the latest. Next is the RF section which, I suspect, is a
whole other can-o-worms.
