See the Hackaday project page.

Almost the same as v1.6.3, but adds pi network to one output for a 13 dBm into 50 Ω sine port.

I have a 15 MHz Oscillator. My TIA accepts 1, 5 or 10 MHz. This board is a divide-by-3.

• IC1 & IC2 - dual D flip-flops
• IC3 - quad 2 input NOR gates
• C1-3 0.1µF

Inspiration came from here.

This board has the traditional 2 NPN transistor alternating oscillator circuit… but with SMD components to proudly proclaim your achievement!

• Q1 & Q2 - MMBT3904
• R1 & R2 - 0805 100Ω
• R3 & R4 - 0805 100kΩ
• C1 & C2 - 0805 10µF

And two 0805 LEDs and a CR1220 battery clip.
