Robin, I second Don's comments. To add, have been using my KXPA100AT with the 705 and have found it simple and trouble free. I know of quite a few other who do the same. Good discussions of that on [email protected] list.

The KPA100 depends on internal signals from the base K2 such as AUXBUS and several other signals to operate and control power output. In other words, it is an amplifier dedicated to the K2 and not a general purpose amplifier. The KXPA100 and KXAT100 would serve you better than cobbling up an interface that would be quite complex. he signals needed are those in the 9 pin AUX IO connector. AUXBUS allows the base K2 firmware to 'talk' to the KPA100 firmware IC as well as the KAT100 firmware. 73, Don W3FPR On 9/29/2021 10:59 AM, Robin Tew wrote: > Hi All > Just thinking about using the KPA100/KAT100 EC2 Combo with the Icom 705. > > Any pointers,ideas,tips etc. To achieve this?. > Many thanks > Robin G4JDO > > ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
