Seems there's missing component values of the amplifier in the article in the Dec 2008 magazine. I don't receive the soft version of the magazine, maybe the values are in there? Could anybody supply the component list?

I don't have the BOM for that article - the on-line edition
is a clone of the print version in PDF format. (With the
incredible advantage that you can click on embedded
links and jump to web pages or email the authors, etc).

From the text I gather the input op amp is a TL072,
and the output amp is an LM386.

It seems that this is a "kit only" article, available from the N & V store.

This is a poorly documented article, stating only 4 components: TL071,
LM386, R9 = 10 ohms, D3 is a 5V zener. The rest, who knows? Though
the hardware aspects are described well, all the screws, standoffs etc. are
there. NV should post an apology and a parts/vendor list of all components
on their website and in January's issue.

Don't assume they know of this problem or read this forum.

Actually, someone over there actually does read and post here.
Yes, he is the website guy, but still a part of the team.

Robin Lemieux - [email protected] - Assoc. Pub./VP Sales/Marketing

Those without an email addy:
Jack, Audrey and Shannon Lemieux, AJ Cohen and Debbie Stauffacher.
They can be reached via snail mail.

Last, but in no way least, the contributing editors, ever changing, including yourself.

Actually, I believe it is Bryan who should be contacted. Usually, the editor
is most responsible for the quality of the content in a publication.

Thank you for your direction.

After reading the article it occurred to me that a
laser pointer could be placed on the microphone
stem, to provide a target marker. The listener
could then aim the dish by looking for the dot.

Hmmmm. With that mod, it might not be a good idea to use the ear to hear what they're saying in the Presidential motorcade!

The parts list was inadvertently left out the article. It has been available since the website was updated to the December issue... Sorry for the confusion.

Might be a good idea to check there for missing files. That's where all the article files go for readers.

Thanks Michael, I was unaware of that. Request retracted.
