Morse code is called the original digital mode. Radio telegraphy, designed for machine-to-machine communication is the direct on / off keying of a continuous wave carrier by Morse code symbols, often called amplitude-shift keying or ASK, may be considered to be an amplitude modulated mode of communications, and is rightfully considered the first digital data mode.
The IRLP software cannot decode the D digit (the bottom right key on a 16-button DTMF dial). This is a limitation of the hardware in the decoder. DTMF digit D is logic level 0 on all 4 bits from the MT8870. Thus, the parallel port pins would all be at 0 volts, which IRLP regards as no DTMF digit present.

The protocol has been integrated into several hardware and software projects. [ citation needed ] In 2021, Kaczmarski received the ARRL Technical Innovation Award for developing an open-source digital radio communication protocol, leading to further advancements in amateur radio.
Digital mobile radio (DMR) is a digital radio standard for voice and data transmission in non-public radio networks.It was created by the European Telecommunications Standards Institute (ETSI), [1] and is designed to be low-cost and easy to use.
A waterfall display showing FT8 in use on the 40-meter band.. FT8 (short for Franke-Taylor design, 8-FSK modulation) is a frequency shift keying digital mode of radio communication used by amateur radio operators worldwide.
It has met criticism from the amateur radio community because the nature of its patent [1] and licensing runs counter to the openness of amateur radio, as well as usage restriction for being "undisclosed digital code" under FCC rule 97.309(b) and similar national legislation.
