A friend of mine had a need for a round 500Kbit baud rate. What he did
was use some FDTI USB/RS232 chip.
He could patch the timing values for an existing baud rate (300 baud or
something else normally not used). I believe in the Windows registry.
This way the (terminal) software can select the

Well, apparently I screwed up and didn't write you directly.

Are there any terminal programs out there that allow you to select rates
other than the standard values?
You can use the wonderful Tera Term (http://ttssh2.sourceforge.jp/):
it accepts nonstandard values
Gentlemen,
I know this one has been asked a few years before but I give it another try:
Has anyone of you a Stanford Research FS700 schematic available that he can
share with me?

I have the manual and a working FS700 now. Maybe able to copy several pages.
Need to find a scanner for 11X14, and not sure when I can do that.
What problem are you having and perhaps we should take this offline.
Regards
Paul.

Several issues here:
1. Making a precision crystal like the 10811 one is very involved.
It cannot simply be rescaled to a different frequency. It represents
a whole new design. This is not like ordering custom crystals for
your 2 way radio (back in the day).
2. The 10.23 MHz crystals I am
Paul,
You can do it in a common scanner in two parts, then using any graphics
editor (i.e. Photoshop) rotate one of the files until they match and
paste both. I do it routinelly with all my oversize schematics. Or
just scan and let someone do the assembly (I can volunteer for some).
I have a 10.23 MHz 10811 oscillator out of an early GPS simulator
somewhere, so, FWIW, HP did make at least one. I remember it because I was
disappointed it was not 10.000 or 10.24 MHz.
Best,

Paul,
I just received an answer fom TVB. Before you engage in any kind of business
concerning the copies let us wait whether Tom has the schematics.

Given that this is an extremely sensitive topic and completely illegal
also, let me just state at the outset that I have no interest in
jamming anyone's GPS. A while back, I was looking at one of those
Chinese discount electronics websites, I'm sure we all have, and
noticed a GPS jammer for sale.
My thats a reasonable answer indeed.

Looked at the schematics front end is simple. Essentially op amps notch
filters and most important electronic selectable attenuators. Any of it
could cause issues. But the good news is a amplified loran signal is on the
back of the unit so you could look to see whats happening to the signal.

There is *very* little signal hitting the ground from a normal GPS bird. Even a

GPS does not use a lot of bits in the front end A/D.

If you run through the article the author claims that he's getting a few
hundred feet of range with a few hundred mw of power into a good antenna.
Your cell phone and FM broadcast radio are equally susceptible under typical
conditions.
