I then compared the
http://www.amwindow.org/tech/htm/alowdisdet.htm unit with the AD607
synch detector. The synch detector is the clear winner.


Do you have a link to the synch detector schematics?

Pete KE9OA kindly sent me a diagram for a MW
receiver that he designed and built. The AD607 PDF
gives pin out and other data.

Thanks for the info. Now we'll see, if Pete is willing to send me the
schematics?

The AD607 has a PLL built in and I don't know why this designer
didn't employ it instead of adding a NEnnn PLL. But at least it shows
one way to use the AD607.
I am presently using a ARRL BFO deign from the early 1970's that
works, but has developed some nasty drift issues in the 30+ years
it has mainly set idle. I am debating using 3 Epson programable
for the BFOs. I can either go with them running at 3 times the desired
Fout,
or hihger mutliples. At 13.nnnMHz the phase noise is on teh edge of
being too high,. but for less then 5MHz the phase noise is minimal. I
have a query
to Espon tech support to find out at which freqs they have minimal
phase noise. Supply them with +5 or +3.3V at 10mA and they give very
stable
Freqs. I have one 455KHz crstal, but it is sluggish in every circuit I
have
tried it in. I can get three of the Epson uints for less then a "good"
crystal.
I want one at 455.0000MHz and one at +1.300 and -1.300 KHz.
I am building this as a series of modules each in it's own Altoid Mints
tin.
A friend gave me a BIG Altoid tin that has more then enough space for
everthing.

E-mail me directly, and I will send you the design
