VFO to DDS Conversion steps

Chris Coel
 

Hi BitX Group, I got my DDS kit upgrade in the mail. I cant remember on yahoo groups if there was a conversion instruction for the VFO to DDS kit..

Aside from the plug in and calibrating which already exists on the HFSigs site.. What was the component or components that need to be removed/added to the board to allow it to work properly with the DDS kit that we could purchase from HFSigs?


Thanks!
 

Remove L4. Not sure if there was something else or not.

When I got my QRP Labs VFO kit I simply removed L4 and plugged in the cable from the VFO. You can remove the trimmer cap next to L4 also but there's no need really. It made no difference for mine.

I just lifted one of the L4 connections to the board and left it in place all be it not connected to the circuit at on end of the inductor. DDS works fine with no known issues.
