Soldering crystals through wires
433MHz and breadboards don't mix.
Breadboards have inductance in the pin rows, and capacitance between the pin rows.  These will completely mess up any circuit that operates at radio frequencies.
The inductance and capacitance are a side effect of the way breadboards are built.  There's not a bunch of coils or capacitors inside that you could remove.
At exactly what frequency breadboards become unusable depends on the breadboard and the circuit used.
Regardless, 433MHz is far outside of breadboard territory.  Your crystal or whatever it is will not operate on a breadboard, and the 433 MHz signal will not travel well (or at all) down plain jumper wires.
What you are trying to will not work.

433 MHz is unusual.  You'd normally have a lower frequency crystal and use a frequency multiplier of some kind to get the 433MHz.
Are you sure you aren't using an oscillator module, or a radio transmitter or receiver module?
