RTTY - FSK vs AFSK: which is better
https://www.ik3qar.it/rtty/3/
In FSK (frequency Shift Keying), the mark and space frequencies in transmission are operated directly by RTX (which thereby must have the FSK mode) through a built-in modulator. Reception is in any case operated by the sound card. In AFSK (Audio FSK) instead, mark and space are operated by an audio oscillator outside the RTX, which therefore ...
AFSK vs. FSK - Newbury and District Amateur Radio Society
https://nadars.org.uk/afskvsfsk.asp
Audio Frequency Shift Keying is generated by shifting the frequency of an audio oscillator that is fed into the transmitter's normal transmit audio input. Unlike FSK, AFSK can be used for FM modulation. The frequency of an FSK system is easily determined by reading the transmitter's dial or crystal frequency.

Not Black Magic: AFSK
https://www.notblackmagic.com/bitsnpieces/afsk/
This is where AFSK comes in. AFSK stands for Audio Frequency-Shift Keying and it encodes the digital bits into two audio tones, a space tone that typically encodes the ‘0’ bit and a mark tone that typically encodes the ‘1’ bit. AFSK is popular amongst Radio Amateurs and is used for the for the Automatic Packet Reporting System (APRS).
RTTY - FSK/AFSK interface - Diagrams and tips
https://www.ik3qar.it/rtty/1/
Rtty interface (FSK/AFSK) with sound cards. Or how to remove the so called "ground loop" and the reentry in the RTTY broadcast and make radio and PC happily coexist. One of the problems that affects our digital broadcasts which make use of audio cards, as for instance RTTY and PSK 31, is the reentry of the signal between RTX and the PC.

audio fsk modulation Elits, AFSK operates by sending a mark and a space, each represented by a different audio frequency, to the transmitting medium (e.g. a telephone wire) depending on the input data is a 1 or a 0 from a transmitting terminal or source (e.g. a PC)

Much like receive audio from radio to sound card, the circuit is the same going back the other way for transmit. Even though I use FSK, I do use this circuit when running AFSK for PSK31 operation. I placed a 47k ohm mini-potentiometer across the microphone input to further reduce the audio going into the transmitter.

AFSK vs. FSK (Audio Frequency Shift Keying vs. Frequency Shift Keying) The biggest decision you will make when you begin to set up for RTTY, is whether you want to use AFSK or FSK to transmit RTTY. Either way is acceptable. There is an excellent explanation of AFSK and FSK in the MMTTY help file so I won’t go into a lot of technical detail here.
