Rather surprising you only saw a fraction of a volt from the si5351 at 35mhz..
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.
The si5351 outputs should work up to something like 200mhz.
(Though my library is only good to a bit over 100mhz, as it does not mess with varying the vco frequency).

At 35.5 MHz that level dropped to less than 0.25VRMS.
