You might put a 1K in series with the input.? Thus it would take a larger signal but load the test circuit less.

Try on the gate of the IRF510?? That's a pretty good stiff signal at your transmit frequency.

Try it on the SL5351 output.

It is good to experiment, this radio has a lots to learn about!

It is a wonderful base to experiment with.? I will use mine mostly for playing with the receiver and Arduino code.

I don't have an antenna.? So it will be a long wire out the door and /or the Signal Generator!

I have already made PCBs (stamp sized) for the Silicons Labs oscillator and have a Nano driving it with I2C.

The examples in the Arduino Code work!? Sweeping, Fixed Freq. ect.? The library makes it magic.

Nothing in particular, trying to learn.

What do you want to measure?


It has 100 Ohm input resistance on input transistor base ( Cap Coupled).? So you need to find a signal somewhere that this low impedance won't load down?
