Re: KX2


There is no such single cable, because there is no USB connection directly to the radio. The DTR and RTS control line inputs on the radio control serial port are not implemented in the KX2 and KX3, so hardware CW and PTT keying on the radio control port (as in the K3/K3S) are not possible. There is no USB audio codec inside the KX2 or KX3 either, so sound card digital modes need a sound card external to the radio (the same as the original K3).

CW keying can be supplied either by a hardware connection from a keyer (such as mortty, a winkeyer, or a serial port keying interface on a separate serial port, etc.) to the radio's Key jack, or by using CAT commands. Audio in/out for wav files and digital modes can be done using the radio's Mic and Phones jacks and a computer sound card.

Has anyone successfully integrated a KX2 with N1MM+, including CAT, CW keying, and audio in/out (for wav files and digital modes)?

The so-called “USB cable” that comes with the KX2 only provides CAT functionality (unlike the K3, which has everything on the USB port). Is there an available cable/cables to complete the picture?
