-**Telegraphy modulated** is an operation mode in which the RF carrier is modulated with a tone frequency in the rhythm of morse code (in the very early years of wireless telegraphy, often the frequency of the power generator has been used for this).+**Telegraphy modulated** or **modulated tone telegraphy** is an operation mode in which the RF carrier is modulated with a tone frequency in the rhythm of morse code (in the very early years of wireless telegraphy, often the frequency of the power generator has been used for this).
  
 In contrast to the unmodulated carrier of A1-transmissions,​ which is not audible in a standard AM radio, these tone modulated signals can be heard with a receiver in standard AM mode or even with a very simple crystal detector set. In contrast to the unmodulated carrier of A1-transmissions,​ which is not audible in a standard AM radio, these tone modulated signals can be heard with a receiver in standard AM mode or even with a very simple crystal detector set.
