The DDS Version 4 is an excellent project for using with any tcvr. Many Ham's are now purchasing the PCB and building the DDS 4 Project.
work's with the Bitx, but it is a complete solution for a multi band Bitx.
The Latest to build the DDS 4 is G6AJW OM Dave Lucas from U.K who has very kindly granted me permission to publish pictures of his build DDS 4, he is also going to make the Bitx Vr 3 and hopefully very soon he would let us know as to how the Bitx 3 works with DDS Version 4.
