> Anyone having experience of using the KRC-2 together with the K3? Several of us are using KRC2s with K3s. This combination works great. You must power up the KRC2 either before or with the K3 in order for the KRC2 to recognize K3 band changes.
There are different approaches to connecting to the AUXBUS signal on the K3 ACC connector. There are several signals on the ACC connector that you may want to use in your system configuration. One approach is to use Y-adapter cables to provide multiple DE15 connections, to which a (custom) cable for each signal can be used. Beware, though, that some Y-adapters have one or more pins or wires missing because in the typical use of these adapters for video, those lines aren't needed. The K3 ACC DE15 does use all 15 pins. A second approach is to make up a custom cable where multiple cables run from a single DE15 to each of the different uses you have. For example, I made up cables with a mini-coax and two-wire shielded cable going from a DE15 connected to the K3 ACC jack. The coax goes to a DE9 for connecting the AUXBUS signal to the KRC2. The other cable goes to another DE9 for connecting the K3 FSK and PTT inputs to the PC Serial COM port for RTTY. > I need an interface to control my remote TX antenna switch > but maybe the > KRC-2 is overkill? Perhaps. Depends on what your antenna switch requires. Rather than the KRC2, you can hook up a BCD band decoder to the four lines on the K3 ACC connector. The W9XT decoder board is small and cheap. Several K3 owners have mounted this PCB inside their antenna switch and just run a four-wire cable (plus ground) from the K3 to the PCB/antenna switch unit. 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
