I have a microHAM DigiKeyer II that is surplus to my needs. It includes a cable for the Elecraft K3 transceiver as well as an USB cable. The DigiKeyer II (serial #959) works perfectly and is in great shape although you may find a small surface scratch or two (I can't see any, but they may be there). If you're not familiar with the DigiKeyer II, here's the description from microHAM: "DIGI KEYER II™ is a powerful All-In-One USB interface for amateur radio digital mode operation including RTTY, PSK31, MFSK, Olivia, WSJT, APRS, PACKET, and many others which builds on the proven DIGI KEYER. DIGI KEYER II™ includes a rig control interface for all supported radios (Elecraft, Icom, JRC, Kenwood, Ten-Tec, and Yaesu), an internal Stereo sound chip using standard Windows Sound drivers, K1EL WinKey CW Keyer, and independent PTT outputs for both LNA and Power Amplifier control. " I do not have the manuals or discs, but everything you need is available for download from www.microHAM-usa.com Price is $200, PayPal only. I'll pay priority shipping and insurance anywhere in the United States.
