The DDS 128Mhz Clock frequency is now generated with a VCO and PLL locked to the 12.8Mhz TCXO (Temperature Compensated Xtal Ocillator)
The same PLL and VCO IC also generate 10.7015 Mhz (the BFO freq for USB). It cal also generate the LSB signal, when in LSB mode.
Read about the DDS for more info about it.
See the whole breadboard test setup
I have also tested the NEW Amplifier board here it's used to filter and buffer the BFO signal that is feed into the last mixer.
