Adding an OzQRP CDV DDS VFO to the non-DDS Bitx40 transceiver.  Describes how I fitted this and audio AGC to make this rig more usable. The controls on the front panel are, from left to right: AGC level, AF gain & Tuning. 

Note: The current version of the Bitx comes with a DDS VFO. But it may benefit from the audio AGC.
