That is not totally true, for me at least. I went through all bands and set up the power with and without the KPA500. 99% of the time, going anywhere with the KPA500 in stby, I get 100W from the K3. 97% of the time, then going to oper, I get 500W from the KPA500. Roughly 3% of the time, after tuning the external ant coupler [REALLY anxious for the KAT500!], putting the amp in oper gives me TUNE pwr [5W for me] from the K3, and around 60 W from the 500. So far, the only way I've found to get it back to normal is to rotate the PWR knob back to 27 or so watts. 1% of the time, or even less, going to oper on the KPA500 leaves the K3 power at 100W. First tap on the paddle lights everything up, and it shuts down with the fault light on. On a couple of occasions, I have had to unplug the KPA500 for a minute or so. None of this is reproducible, at least in the time I'm willing to spend trying to reproduce it. It just happens, sort of on every third Thursday after the first full moon after the equinox. I would really like the display B messages on the K3 to show the power it is going to transmit with the next time I tap the paddle when the KPA500 switches between STBY and OPER. I have my KPA500 set to go to STBY on band change so this is a fairly frequent activity. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org ______________________________________________________________ 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
