The last issue of QST had a short article on the CircuitMaker Student
edition circuit design package. I downloaded it and spent several
hours trying various oscillator designs (including the phase shift
oscillator discussed in the same issue of QST). I couldn't get any of
the designs to oscillate! I was mainly trying Colpitts oscillators.

Has anyone else tried designing oscillatos with this application?

Thanks,
Ed Bailen
=====================================

Not good.

I hope that you will notify ARRL (or have) about this.

If there are serious deficiencies in the software (regardless of whether
it is free or not), then possible users should be made aware of them.

Thanks for letting me know, just in case I try to use it.

I have a Colpitts oscillator running ok in Circuit Maker Student V6.2c.
I can send you the file if you'd like. (small, about 13 kb)

I should add, there is one thing (at least) that you have to be aware of
with CM. Wires that look like they are connected may not be. Use
Simulation, Check Pin Connections. This should tell you any pins you think
are connected but which CM thinks are not connected.

John, I'd like to take a look at your circuit if you wouldn't mind
emailing it to me. Thanks.

Thanks to the rest of you for advancing my education.
