The simple way to use a SteppIR antenna (any version) with K3 and logging program is to use SteppIR's 9 pin "Y" cable and RTS_S13 transceiver interface cable.
The common leg of the "Y" cable (DB9F) connects to the computer serial port or USB to serial converter. The "Radio" leg (DB9M) of the Y cable connects to the "SteppIR" end (DB9F) of the RTS_S13 cable, the "Radio" end (DB9M) of RTS_S13 connects to the K3 (or P3) and the "SteppIR" end of the "Y" cable connects to the DATA IN jack on the SteppIR controller. Configure the SteppIR Transceiver Interface Mode to Kenwood/Elecraft at 38,400 bps, Set your logging program, K3 and P3 to 38,400 bps and configure the K3 CONFIG:AUTOINF = NOR. Turn on the Auto mode (SDA-100) or General mode (Original controller) on the SteppIR. The SteppIR controller will respond (follow frequency) to data from the K3 in response to the logger's polling as long as the logger is running. When the logger is not running, the Autoinf=NOR setting should cause the K3 to send frequency data every time the VFO knob is moved. Beware that *some* computer serial ports/serial to USB converters will load the K3 data output lines when the computer is turned off. It may be necessary to disconnect the cable from the computer serial port/USB to serial adapter when the computer is turned off. 73, ... Joe, W4TV On 2015-06-08 2:37 PM, [email protected] wrote:
