Adding a CDV DDS VFO to the non-DDS Bitx40 transceiver

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.

Hi Peter this is interesting as I have been trying to get it on frequencies but seemed like it was on the upper side but could not tune it in will give the cap ago. What changes did you make to the program of it like the if above or below. Thank you again for the resonators they have been working well and I made your agc unit up with a meter. Kevin vk7hkn
