I checked the drive at the DDS input and found it to be 1vpp.
(from internal VCO)
I did this because I plan to add a DDS also and have a few. I have 2 of the N3ZI ver.1 DDS
and 2 homebrew Uno>9850.? I also have 2 of the Si boards.
Any thoughts on which one ??? I think the N3ZI wants 200ohms....no idea on the others.
