I purchased my Bitx40 last December. Everything works great. I’m trying to use items I already own to build a DDS. I connected a AD9850 with an Arduino Mega 2560. I added a contrast control, an LCD display and a rotary encoder.
I used the sketch found here:
The DDS works. I connected my DDS to the DDS pins on the Bitx40 near L4.
What changes do I need to make with the pre-Raduino Bitx40 to use a DDS? Remove L4? Keep or change caps in original VFO?

Thanks in advance,
