Main function
- CW - complete K3NG code
- Winkey emulation / CLI interface
- Memory button
- Speed rotary encoder
- Keying from PC com port (DTR/RTS)
- SSB
- Switch TX audio between Microphone (Foot switch PTT) and USB Audio (com PTT)
LCD
- First line show
- TX signal in CW and FSK mode
- RX sniffing decode RTTY (lowercase) during keying from PC
- Second line show
- SD card detect
- Ethernet module detect
- Band data
- Active Mode
Odpojovani usb
- vysoky potencial (namereno 80V AC) mezi USB-GND a TRX-GND, obvykle staci:
- uzemnit skrinku
- vymenit zdroj (nevhodne jsou male spinane adaptery bez zemniciho vodice v zasuvce)

Hardware dependancy
| Mode | Source | Outs | ||
| PTT | CW/FSK | WINKEY | AFSK | |
| CWK - CW keyer | PTT1 | CW1/2 | HIGH | LOW |
| >CWD - CW daemon (PC) | RTS | DTR* | LOW | LOW |
| SSB - LSB-USB-FM | RTS/FootSW | - | LOW | LOW |
| >FSK - EXTFSK | RTS | DTR* | LOW | LOW |
| FSK - Serial ascii | PTT1 | Serial | HIGH | LOW |
| DIG - USB audio codec (AFSK) | RTS | - | LOW | HIGH |
* JP4 jumper must be set CW or FSK
Note - character ">" shown external signal source
- WINKEY HIGH - disable DTR/RTS
- AFSK HIGH - switch TX audio path
