I just discovered why so many MOTM messages are getting tossed. I have a
junk mail filter on Outlook and it scans for several things (I'm not allowed
to control the base list)
In the "Yahoo! Groups Sponsor" message below, it says "Order Now" and that
is one of the key phrases.
Stupid tools are supposed to HELP not hinder.

> Disadvantages:

> No LED to indicate rate -- you'll have to use your ears, tough guy.
> No simple "rate" control for tri waveforms (you need a mult).
> No simple "PWM" for pulse waveforms (you need to modulate HOLD).
