 | | While setting up your equipment for digital operation, however, it is important that you understand the differences between the two keying methods provided on the FT-920 for digital mode operation, so that the controls and switches may be set correctly. |
 | | For typical RTTY operation, select 2125-L; this sets the carrier injection up for an offset of 2.125 kHz in a pseudo-LSB mode, so that the transceiver actually is operating in the "LSB" mode (even though the display still indicates Data-USB). |
 | | As with AFSK operation, the "CW" filter may be engaged in the FSK mode by pressing the [Narrow] key, and the DSP filters may also be used to reduce interference in crowded digital operating situations. |
