One solution is to build a "breakout box" to move all of these interconnection problems away from the K3 itself. Since I also wanted to make a shallow base to raise the K3 about 1.5 inches above the table, both of these functions have been combined to make a "breakout base" on which the K3 stands. A short 15-way cable connects to the ACC socket of the K3, and all of those 15 lines are fanned out to a stripboard patch panel inside the base unit. Another short cable connects the switched 12V output from the K3. All of the input and output signals that would otherwise go to the ACC connector are now routed to individual connectors on the 10in wide rear panel of the "breakout base". These currently include FSK input from the PC, PA inhibit from the SteppIR, additional band data outputs and three 12V outputs switched by the K3. This will perpetually be a work in progress, modified to meet current needs. For example, when an SSPA came on the scene, it was very easy to tap into all the necessary control and band data lines, and gather them into a custom umbilical cable. One day I shall complete the front panel of this unit, which currently stands empty. But, like Dick... >Unfortunately I have more ideas than time to implement them. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ______________________________________________________________ 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
