Hello, I've found a schematics on web, i've tried to build on a breadboard but it didn't work. Then I thought the problem was testing with a breadboard and i did my own pcb tested over there but it didnt work again.
I'm not good about transmission, electromagnetic, but i have to do that project. Can you help me about analyzing schematic if something is wrong?

C1 is 1nf
C2 is 4pf
C3 is 10pf
C4 is 10pf
R1 is 5.1M Ohm
R2 is 8.2K Ohm
R3 is 75 Ohm
R4 is 27k Ohm
Q1 is 75.025 3rd overtone crystal
L1 should be around 0.05uH as i calculated
L2 is 8 turns on 1/8" diameter.
T1 is NE68119-T1-A but instead of that i used 2n3904
T2 is MMBTH10LT1G but instead of that i used 2n2222
