Hey Eternal Squire,
If you make any changes to your bmps, let me know and I'll remake the gifs.

Hi! Ron!
Thanks for all the efforts .
The automated system appears to have some flaws. My observations
1) Zobel at output pin 5 of 386 has cap marked 100pf this appers to be an error, similarly

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

Very nice job, Eternal Squire!

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.
Basic design isa fairly stock PI form and uses 4 diodes
to attain about 40-45db of attenuation.

Re: Nicely drafted BITX schematics.
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
have it.

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,

Double sided layout for Ver3
Hi!
Few friends have shown interest in making a double sided board for
BITX with top layer unetched and acting earth plane.
I have uploaded the artwork files to make it easy for them.

Hi!
It would be a simple matter to upload the interconnection traces only less the earth plane. I will simply reamove the earth plane from V3 layout.

Nicely drafted BITX schematics.
All,
I'm starting to need reading spectacles, so I took the liberty of
redrafting the schematic submitted by Mr. Farhan into a series of

Re: New to group and Query
Most of this V3 board is IF and BFO and as such is well shielded by
the prolific ground plane on it's single side.I like this type of

Re: New to group and Query
Hi,
It's size and the lack of two sides (top ground plane) make it
less than useful for my 6m project. I'm saving it for something
else. I mentioned it so others may know that FAR has it.
