A benefit of Elecraft's not including multiple antenna outputs in the KPA500 is being able to price it lower and not forcing customers to buy a capability that they don't need. The Alpha 9500 has a sophisticated 4-antenna output capability, but that adds to the price whether it's needed or not.
Jim N7US -----Original Message----- Yes, the band data lines can be paralleled to the KPA500 and another antenna switching device. The KPA500 order page offers an optional accessory cable kit for use with the K3 (KPAK3AUX) that contains of a cable and a "Y" connector for the AUX connector for just such a purpose. The advantage of doing it this way, rather than having the amplifier involved in antenna selection, is that automated antenna switching is available whether the KPA500 is on or off. Band changing with antenna selection can indeed be made automatic. It requires a little more hardware than the K3 and KPA500. We don't offer a band decoder of our own, but we work well with the many decoders that are already on the market. There are a lot of possibilities when one considers antenna switching arrangements. If we offered a 4-position switch, someone would need 6 or 8 or 10. There are a good number of options available from a number of fine manufacturers and there have been a number of construction articles in the amateur literature. I'd look first to the NCJ archives if you want to "roll your own". 73 de Dick, K6KR ______________________________________________________________ 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
