Re: CW Offset does NOT work on Raduino_v1.14.1 for BITX40

 

Hi Hidehiko-san

Yes you could be right.
Another possible cause could be poor grounding of BITX main board and
Raduino board.
If Raduino board is not grounded perfectly, some small potential
difference may exist between BITX board and Raduino. As a result, A0 input
will not be perfectly zero volts when PTT is not pressed.

I've put the 10k pull-down register at the "A0" and maybe the problem
seems to be fixed now. This issue caused by the threshold problem?
