Re: BITX40 First version (Through hole type) - Wiring Up diagram required

Farhan first built his BITX-40 as a board-and-parts kit for a local Indian ham club.?
I think that is the thru-hole version that is being discussed.? It was success of that
kit that probably caused him to embark on BITX-40 semi-kit boards as a product.
I looked back through my files but could not find a copy of the early BITX-40 design.
What I did find is an on-line reference which may have most of the information that
the original poster requested:
That reference even has a video of Farhan himself talking about the project.
Hope that helps.

Perhaps I missed it.
Could you give a web link to something that describes the through-hole board you have?
First bitx version from 2004 is here: ?
and includes files for a throughole pcb at the bottom.
There have many many different kits over the years for throughole Bitx variants from various vendors.
I believe hfsigs started out selling the Bitx40 pretty much as it is now but with no Raduino board for the Si5351 VFO..
And that kits from hfsigs has always been surface mount.
If you mean you need the wireup diagram for the pre-Raduino (but surface mount) Bitx40,
that was posted to this forum early this year, somebody should be able to point it out to you.
Same as the current wireup diagram except that you must have L5 stuffed?and not have
anything plugged into the nearby DDS1 connector. ? L5 is the coil for the analog VFO.
C91 and C92 have been getting removed by some with the Raduino so it works well for USB,
those two caps must be present if using the analog VFO.
