The front panel has a CW Speed control, an input jack for CW paddles, and six LEDs providing status of Radios 1 & 2 – PTT (push to talk, red LED) , CW Transmit (green LED) and RTTY Transmit (yellow LED). The rear panel has a USB-C jack to connect your logging program and two 3.5mm TRRS (Tip, Ring1, Ring2, Sleeve) jacks to connect two radios.
