Nearly all radios and ham logging software use only pins 2, 3, and signal return for radio control and information. The K2 uses the other pins on its DB9 connector for other functions that are VERY different from the RS232 standard. The SteppIR controller I own (the newer SDR100) monitors the serial line for frequency instructions sent from the computer control program to the radio, and will change frequency to follow those instructions. I don't believe that it gets frequency info from the radio. Or perhaps it doesn't when there's a computer controlling the radio. To clarify that, to make the SteppIR change frequency, I must use my logging software to tune the radio. For example, in N1MM (and in several others) I can send the radio to a frequency (14050 kHz, for example) by typing 14050 into the entry window. I can also change bands with <CTRL> <PG UP> and <CTRL> <PG DN>. In both cases, the SteppIR controller will follow it. But if I change bands on the radio, the SteppIR controller doesn't move. I don't know if the SteppIR controller works with the K2. You should call them and ask. When I was getting mine set up, I had several conversations with their support guy, and he was quite helpful. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
