I would love to see that Incorporated into a 2 M transceiver because I'm not aware of any commercial Ham radios that natively send text (yet).
But during emergency nets some of us use Fldigi (short for Fast light digital), a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem.
The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB transceiver or an FM two way radio to the computer's headphone and microphone connections, respectively.

It can be difficult for some to get set up and properly configured, but once it's working, it will transmit text messages without major errors under the noise floor, i.e. can barely hear it because of all the white noise.
It does cause complaint's when used on voice simplex frequencies and repeaters.
It sounds worse than packet radio https://en.wikipedia.org/wiki/Packet_radio https://en.wikipedia.org/wiki/Packet_radio which I kind of like hearing.

- Mister_X 6y agoThanks, I'm well aware of APRS, it's a neat technology, I know many Hams who use it, but don't feel the need. I travel long distances on my motorbike as often as I can, I go naked, no phone, no eletronics except my 2M transeiver and point and shoot camera.
- vel0city 6y agoWell, you're asking for amateur radios which natively send text, and there are many amateur radios which natively support APRS. APRS can send text. Hitting an I-GATE, they can send and receive SMS. So from my Kenwood TH-D74A I can natively send and receive text. There are many radios out there which natively support APRS, which means they natively support text. Many other radios can natively support this text functionality. It seems like its the thing you were requesting in your earlier comment, but you're brushing it away. What is APRS lacking in terms of text transmission?
