[DSP-10] Documentation discrepancies

Wed, 24 Mar 2004 19:46:15 -0700

Hello Jay,

Thanks for the feedback.  It is very much appreciated.

The color highlighted drawings are originals that Beb supplies with the PCB.
They have not been updated with all the changes through the years.

I started the assembly manual to hopefully pull everything together with
updated information.  Still, it is the best practice for anyone putting a
DSP-10 together to double, even triple check a value before committing it to
solder.  The DSP-10 is a complicated device.  The good news is that many
people have successfully assembled and have running their own personal
DSP-10.  And after all that work, there's a sense of uphoria!

If ever in doubt, ask on this list.  There are many who can help.

Good luck in the rest of your assembly.  Let us know when you are on the
air.

73,

- Steve, N7HPR
