Hi Jim,
Thank you for your post and the information page you provided,
I'm going to add it to my Com-Spec Information Archive.
I've been a long time user of the TS-32 encoder - decoder
unit, which is no longer made. Robert at Com Spec told me
they could no longer get their custom chip made by Hughes
Semiconductor so the TS-64 is the next generation.
The TS-64 adds some well received additional features and
has some "minor" equivalent function changes compared to the
TS-32.
The major function change mentioned above is related to the
high pass audio filter input now being hard connected to the
same Discriminator input used for the Low Pass Filter. One
is forced with the as-built/supplied TS-64 & TS-64 DS Model
to use the un-squelched Discriminator Audio (if connected per
the instructions).
The hard tied dual filter input connection is a major pain
if you/I want to source the high pass filter audio from a
different location (like a de-emphasized, squelch muted
location - high side of the volume control pot in many
receivers). If I need that option I now have to de-solder
capacitor C12, remount it with one end floating and add a
filter input connection/wire.
There is a special as-built for Daniels Electronics version
of the TS-64 DS with separated filter inputs. Com Spec says
you must contact Daniels Electronics to try and obtain that
special version. :-(
The high pass tone filter mute is gone on the TS-64, but
I never used it and the equivalent function can be emulated
using some of the TS-64 outputs.

The other issue is the mystery dip switch daughter board
supplied with (soldered on the bottom) the TS-64 & TS-64DS
units. There are a lot of unused solder pad connection points,
hence I made call to Com Spec for more information.
Com Spec calls the daughter board the 84-7000
It turns out the TS-32 was used in many other Com Spec and
after market products. The TS-64 daughter board is designed
to emulate the the TS-32 foot-print with the same or almost
exact pin functions. The are some minor differences (as
mentioned above) when using the TS-64 DS daughter board in
a "drop-in" TS-32 application.
The end result part number for the TS-64DS and the 84-7000
is labeled the TSU-64DS unit.
There is no public on line available Data Sheet available
for the TS-64DS Daughter Board but I now have a pdf file
copy of the board trace layout, which makes using the Daughter
Board connection points much easier to locate.
If anyone would like a copy of that information... feel
free to Email me. Maybe Mike or Kevin can put the information
sheet up on the Repeater Builder (Com Spec) Web Page(s).
I really like and use the TS-32 encoder/decoder units...
but if I can no longer buy/find them I have to start using
the TS-64 - TS-64DS units now.
cheers,
