Hi Deni:
So, how about someone comming up with a good communications quality
amplified speaker and enclosure design, RFI proof of course!
I would build one...I believe there was/is an Elecraft design but it
looked overly complex...
Anyone care to suggest a suitable audio chip, speaker and enclosure?
The Motorola amplified (7W to 15W) speakers are GREAT for our uses.
Some seem to be more susceptible to RF getting back into them, but at
$15 (US), not including shipping, they are a great buy, and MOST
(though not all) have proven to be fairly immune from RFI.
I have modification (wiring) instructions for many of the Motorola
amplified speaker models on my web site at:

I also have plans for an amplified speaker which you can build into
a case of your choosing. See:
http://www.n0ss.net/tda2003v_5w-7w_af_amp_v7.pdf
If you wish to BUILD a custom K2 amplified speaker into an EC2 case,
I can supply some documentation. It's not on my web site, but I will
be happy to provide what I have (fairly complete) just for the asking.
73,
Tom Hammond N0SS
