Hello
Yep, I looked at the circuit and the Hendricks kit already has pads for the DDS.
The key question is what can we leave leave out of the board ?
I have not built the board yet.
The VFO seems mostly self contained so I guess I could leave out all
of the components of the VFO part of the circuit and feed the DDS to
the pads.
I will look into that.
Thanks

Hello,
I also have the same kit and am using the supplied VFO circuitry with the
Pacific antenna's digital dial.
I get great reception and have transmitted 1300-2000 miles using a Carolina
Windom in the attic and also a LNR 40/20/10 end fed at about 10 watts.
However I get signal reports of "off frequency" or "distorted audio". Im
still having trouble with the digital dial interfering with the freq. (i use
it to get approximately to desired frequency, then disconnect and tune so my
audio sounds good. Maybe switching to the DDS is the answer.
I would thing that comparing the Hendrix 20 schematic to the Bitx40
schematic would give you clues as where to tie in.
