I am right there with Hank, and probably a lot of others. It's worse when one has an external antenna switch which the KPA1500 can't sense so it's necessary to provide low power from the K3 to avoid a fault because of the different antenna and the tuner can provide the appropriate (already trained) match. Also, switching between ANT1 and ANT2 with different conjugate matches often requires different power levels from the K3 (or other radios).
So, for operator "convenience" I find it necessary to set the K3 power level at the lower point to avoid faults. Sadly, there is now way for the KPA1500 to tell the K3 (or K4) what's going on and therefore what to do. I'm attempting to become smarter with an Arduino and, hopefully, figure out how to automate this. It requires a look-up table to determine frequency, antenna, tuning solution, for setting the exciter drive level. So far, I can spell Arduino correctly four out of five times. That is progress! Next, I will plug it in. BTW, if one's antennas demonstrate little to no reactance and a 50 Ohm match, this is not an issue. That only happens in the movies and on TV (Last Man Standing? who needs a K-Line, obviously). 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ 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]
