i just tryed clicking on some links for the computer controlled transmitter and the page cant be found anymore. Simon can you fix this?

i dont think radioshack sells oscillators anymore so you might want to edit these links.

Which links specifically?
I clicked on all the links on the Computer Controlled Transmitter
page, and they all seem to be working.

Did you get there from one of my web sites:
"http://scitoys.com"
or
"http://sci-toys.com"
or has someone made a copy of my site, without maintaining the links?

i c you fixed it thanks
but now i have a problem building this project
i want to build the transmitter on the circut board but my radioshack does not sell that type of board anymore

so in the photo that is under the black n white drawing with the oscillator upside down with alligator clips on it can you show me where the led is attached(the photo has the following printed under it)

"The green alligator clip attaches to the antenna,"...

thanks

The LED is purely decorative, but if you want to add it, it goes
between pin 5 and pin 7 on the D sub connector. See the drawing
farther down the page.

Just went to radio shack today, they told me they didn't carry 1Mhz oscillators and they couldn't even be special-ordered.

That's why we offer it in our catalog on the web site.

An oscillator is something that oscillates.
A pendulum is an oscillator.
So is a guitar string.

In electronics, an oscillator is something that oscillates
between two voltage levels. Frequently one of those voltages
is zero.

The Christmas light oscillator turns the lights on an off perhaps
once per second. The oscillator in the AM transmitter is a million
times faster than that.
