There is enough space, however, all the signal processing is done by the SI4732 chip so the audio output goes straight to an amplifier. The ESP32 controls the SI4732 via I2C and does not get access to the audio output so sadly without a hardware mod, you cannot do things like Morse decoding which would be neat.
