Re: Nicely Drafted Schematics, Revision A
I have put the revised gifs out at http://www.ham-stuff.net/w5rcm/BITX/ for those who want them.
Squire, I've got no problem if you want to roll these up into your zip file. Go for it!

Ron W5RCM
Very good job on the schematics. This should also help a lot for those who
want to do their BITX as modules.

Re: New to group and Query
Hello,
I have it on paper and in the chassis. It's still pending
getting it to an electronic form.

to attain about 40-45db of attenuation.

Hello,
Is it possible to make those Word bitmap files intosomething like HTML
or other more portable format? Reason? I do not use Word and do not

Re: New to group and Query
Did I miss this attenuator? I am interrested to see the schematic (and
if someone build it, the results).
Thanks,

Few friends have shown interest in making a double sided board for
