I have now completed up to the start of Assembly, Part III, P67, with
all tests and alignments done.
AND BEST OF ALL, it works!! I have actually heard several strong SSB
signals on 40M...... YAAYY!!
Although I am limited with test equipment, I've managed to pass all tests.
But I will hopefully be calling on some higher precision equipment for
the final alignment in due course.
I think one of the biggest lessons I've learned is not to over
compensate for my old soldering skills by minimizing solder too much.
Having got the right brand and gauge of solder, and an appropriate
temperature compensated iron, this heavy handed old vacuum tube builder
became just a little too frugal. Many joints needed an extra touch up
during testing, but hey, I'm learning!
The only thing i have noticed is that the audio gain does not seem to
act as I would expect while listening to an SSB signal - the volume
seems to increase marginally from minimum and then stay constant over
much of the range before increasing slightly at the end . Maybe this is
another case of an extra touch of solder somewhere, or maybe it's a
normal function of how the AGC level works?
Now, it's on to Assembly Part III, P67!!
