[Elecraft] FW: K3/Mini 0

[OGANE YOSHIAKI]

Hi Dennis,
 
I have my K3/0 Mini for 3 months. I spent one month to successfully configure K3, K3/0 Mini, N1MM and DXLab.
 In order for you to update the firmware, disconnect the RRC cable from your K3/0-MINI. Connect your      K3/0-MINI's USB cable to your PC. Open the K3 Utility. K3 Utility should find your K3/0 Mini. My K3 Utility is the same version as yours. Paddle jack is stereo. I am not sure if key and PTT jacks are stereo or not. I am using stereo plugs for them and tip and sleeve do the job. With cabling from the DB 15 to the Aux/Mic and the I/O inputs on the Remote Rig connected, you can connect the computer keying to key, your paddle to paddle, and a footswitch to the PTT. That is exactly what I configured. I have N1MM installed in my local PC, which is connected to my local RRC-1258 via a USB cable. In this configuration, N1MM can CW key the Mini by sending CW on the DTR line. Just like a normal setup of N1MM. I do not use RTS as PTT since I use QSK. When I first got my K3/0 Mini and RRC-1258, I found your posting about the configuration at Remoterig forum. That was very much informative for me. Thank you very much. Hope it helps.
