RTTY Keying

General

Most HF-radios have a special FSK/RTTY keying input which is better to use than AFSK (audio

frequency shift keying) since you don’t need to set mic gain and other settings. The RRC-1258

has a separate serial channel for transfer of 45.45 baud RTTY keying data. The RTTY serial

channel is only available via the USB interface.

When installing the Microbit Setup manager a USB-driver called COMExtra is installed

In your RTTY PC-Software you should select the serialport number assigned to the driver by

Windows, in the example above it’s COM4.
