Phil, AM with its 50% power carrier and sidebands that change in amplitude should present a less harsh situation than RTTY which is 100% duty cycle. There have been reports of running RTTY for an extended time with no harm. But the specification says 500 watts with 10 minutes key down and 5 minutes standby. It should do at least that well with AM.
The KPA500 has temperature alarms should it get too hot, so it should "take care of itself". 73, Don W3FPR On 7/30/2011 2:49 PM, Phil LaMarche wrote: > When running the KPA500 on AM, it there any time limit before unkeying? > While operating, the fan comes on and then it kicks into another speed. > > > > Thanks > > ______________________________________________________________ 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
