"Thanks. I get that. How does it interface to the K3? How does it know it should change bands when you change the rig? I'm thinking back now, and recall some posts about a splitter cable. I'll hit nabble."
Hi Dave: You can order the SteppIR controller with an optional interface board that provides a serial port. You can also order a serial cable from SteppIR to match the K3. It is the S13 cable. You would also need the SteppIR "Y" cable to split your PC serial port to the K3 and to the SteppIR controller. This enables you to run any kind of rig control or contest software and also use your K3 Utility Program while maintaining communication with the SteppIR controller. You could also make these cables yourself. The SteppIR controller follows the band changes and minor frequency changes that you make on the K3 and adjusts the length of the antenna on the fly. On some bands the antenna changes length every 10KHz and on other bands it changes every 50KHz. It is a totally hands-free operation. 73, Mike K2MK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
