I have built this simple FM transmitter.

**broken link removed**

I have attached a picture, sorry it isn't the best picture

Is there any other way I can test this without trying to find the transmission on my radio?

Thanks

It won't work on a breadboard with its wide parts spacing and high capacitance between tracks. 100MHz is too high for a breadboard.

The text says that the coil must be close wound. Yours is spread out way too much.
Look how compact my FM transmitter is on the other site you duplicate everything on. Its small size reduces stray capacitance and inductance that messes up high frequency circuits. It works fine.
