    Does your serial monitor Baud-Rate match the one of the sketch?

Search in the code for the line Serial.begin(###) where ### is a number representing the serial speed, also known as baud rate. This number must match with the baud rate of your serial monitor, otherwise all you get is garbage.

BTW, this has nothing to do with nRF24, this is plain Arduino serial connection.
