To select a data mode, tap [MODE] or the mode icons adjacent to each
VFO to bring up the mode button group.
The following modes are available:
• DATA (generic) can be used for all audio-based data modes,
including FT8, JT modes, PSK31/PSK63, MFSK, AFSK, etc. The VFO
displays the suppressed-carrier frequency, just as when SSB modes are
used for data. USB is “normal” for DATA A. Compression is internally
set to 0. For detailed FT8/JT/etc. setup instructions, see FT8 / JT / ETC.
CONFIGURATION.
• Like DATA mode, AFSK is also audio-based, but optimized for RTTY.
The VFO displays the RTTY mark frequency, and LSB is “normal”. The
built-in text decoder can be used in this mode. Compression is
internally set to 0.
• FSK is identical to AFSK, except that direct modulation is used, via an
FSK data input pin, an attached keyboard, or the keyer paddle
(see Built-In Data Modes). The text decoder can be used in this mode.
For detailed FSK/RTTY setup instructions, see RTTY CONFIGURATION.
• PSK is a direct-transmit mode for PSK31 and PSK63. Like FSK mode, it
can be used with the text decoder as well as a keyboard or keyer
paddle. You can also use auto-spot with PSK mode.
In AFSK, FSK, and PSK modes, multiple data speeds are available. For
PSK: PSK31 and PSK63. For AFSK and FSK: 45 and 75 baud.
Data Mode LINE IN Gain, ALC, and Monitor Level
If you’re using an audio-based data mode (LSB, USB, DATA, or AFSK),
you’ll need to set the transmit audio input level while watching the
ALC meter. You can use the same procedure outlined for voice modes,
above, except that speech compression should be set to 0 if you're
using an SSB mode. ALC deflection should be kept to just below the
"5" level on the ALC meter in modes where low IMD is critical, such as
FT8.
