Send Secret Messages

It’s time to use your Morse paddle and transmitter to send some messages! Turn on your AM radio, tune it to 540AM, and power up the Gemma M0.

Tap out your secret messages — you could be hidden away in a secret location sending information to an operative nearby with an AM receiver and discrete earphone and nobody will ever know!
