Oh, and the si5351 is driving those series schottky diodes through a 6db attenuator, which cuts the voltage in half.
Maybe you had your scope on some low bandwidth setting or something.

If so, hard to imagine Farhan would get the ubitx to work at all, as his first local oscillator is at 45mhz + signal
Apparently works up to a 30mhz signal frequency, so 75mhz from the si5351.
And it has to drive something like 0.6v into two series schottky diodes for them to start conducting.
