Re: [Elecraft] KPA-100 with K3?
Frank, I use the KPA100 with my KX3 and my K2 and it works fine. I replaced the MCU of the KPA100 with a PIC16F876A with my own firmware. The KPA100 is controlled now via its serial port (homemade communication protocol) by PC or an homemade interface (display and controller with serial port). Hardware changes in KPA100 are minimal. But, in all not so easy as it may sound. I aree with Don W3FPR and recommend a KXPA100. 73, paul hb9axl __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KPA-100 with K3?
Frank, The KPA100 is dedicated to the K2. To operate the KPA100, it needs the base K2 MCU to change bands, do T/R switching, and monitor the power output (among other things). Those functions depend on the signals to and from the base K2 MCU. The same is true of the KAT100 mounted in your EC2 enclosure. So yes, the KPA100 can operate as an amplifier, but would need a lot of external control signals. If you are willing to create a digital interface that will provide the proper control signals to the KPA100, then you could make it work, but the expense and trouble to get that working would exceed the price of the KXPA100. 73, Don W3FPR On 7/27/2015 8:00 PM, kg9hfr...@gmail.com wrote: Squinting at my KX3 and my K2 / external KPA100/EC2… Anyone try it?
