Hein, You could do that by sending commands via the KIO2 interface to the K2 - but you would have to implement a microprocessor in your amplifier to accomplish that feat. See the KIO2 Programmers Reference document.
The KPA100 accomplishes similar function, but communicates to the base K2 via the AUXBUS signals - problem is that the AUXBUS signalling is Elecraft proprietary information, so using that is problematic. There is no one signal that can be used to control the K2 power. I would think it easier to provide a switch in your amplifier to shunt the input power off to a dummy load or insert an attenuator - that way all the controls reside in the amplifier itself. 73, Don W3FPR > -----Original Message----- > > Hello eveybody, I often use my K2 with a homebrew PA and a > homebrew tuner, I can easily take the reflectionvoltage from the > foresaid antennatuner and I should like to use that voltage to > decrease the input from the K2 to the PA if the SWR should become > to high. Anybody already experience ?? How to use that voltage in the K2?? > 73 from Hein/PA0NQ > _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
