I am operating the KPA500 KAT500 power combo with the K3. The combination works great and normally makes frequency and antenna changes really simple. I operate on MARS frequencies and normally all works just fine outside of all the amateur bands with the KPA500/KAT500/K3 there is, however, one frequency where there is an issue. When transmitting at about 4.5 MHz using SSB or digital modes, using the KPA500/KAT500/K3 combination, the band indication shoes the KPA500 spuriously shifting back and forth between 3.5 and 5.3 MHz bands. This also affects the amplifier output power. I can also hear what sounds like contact/relay cycling. This makes the combo unusable on this frequency. How can I resolve this problem so that the KPA500 is usable on this frequency? 73 Joe AJ1Y ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
