I refer you page 79 of the previously mentioned book.

What book? The FT101 manual or your £350 law book?

The FT101's a pretty simple rig, Frank. I doubt the manual would be that
long. When Gareth finally sources a copy, perhaps he'd be kind enough to
confirm.

And you have had your answer - the tuning of the BFO has no effect on
the phasing control and vice versa. Do you not believe the answer?

Stating the bleeding obvious which we all knew any way is about as useful
and as relevant as quoting Newton's laws of motion; for neither are an
appropriate
response to the query as originally put.

Sorry, perhaps you could tell us what the question was again. I thought
you were asking if there was an advantage to tuning the BFO half way
between the wanted and unwanted signals. There isn't.

I know, I had one, complete with manual, back in the 1980s. I don't recall
any difficulties tuning up, just don't key up* for more than a few seconds
at a time. Common sense, really.
* or should that be "key down"?

I don't remember a book being mentioned.

Do a search on lamb "crystal filter" and you'll find at least one
article from the thirties where he describes the filter in depth. II
doubt the famous QST article from around that time covers the filter in
the same depth.

I don't think Gareth knew what the question was even as he was asking it.

Hell, if he's really having trouble without the manual, there's plenty of
videos on YouTube of people demonstrating the necessary actions. Or he
could just pop down his local club and ask a friendly soul there to show
him how to operate it.

There is. You get single signal reception for CW despite the wide bandwidth
of
a trnasformer-only IF strip.

That keeps happening to me. I follow a link, and instead of some
interesting text, I'm supposed to watch a video like it's some cooking
show. Sure it lets the masses in, but at what cost?

I'm not a huge fan of instructional radio videos, the majority are poorly
filmed and lit, with horrible sound and with semi-rambling commentary from
the noble but misguided ham videographer. But I have seen some absolutely
fantastic videos. One American chap in particular has a brilliant series on
YouTube but I can't remember it off the top of my head to pass along...
