For this challenge I used the tool [Cyberchef](https://gchq.github.io/CyberChef/).
Cyberchef recognises the ciphertext to be **morse code**, the title being a reference to Samuel Morse, the creator of morse code.
After decoding the ciphertext, we get the flag: SAH{I_S33_Y0U_AR3_A_M0RSE_C0DE_EXP3RT}
