As usual the mechanical side of things is my greatest challenge. That's the receiver in front and transmitter at the back with the DDS VFO beside it. It's built ugly / manhattan style in small metal boxes available from the craft chain store called Michaels. I had initial thoughts of building it in three completely separate boxes for plug and play flexibility but the interconnections got too complicated for me. The transmitter and receiver boxes are screwed together as one unit.
I used an audio style DIN plug for the connection between the DDS and transceiver. The RF is a separate RG174 coax cable into an RCA connector on the back.
The DDS display indicates that the RIT is on with a +70 Hz shift.
