[Elecraft] High SWR problem

[Rob May]

All has been fine with my K3 until today.  The display is indicating  "High SWR" when I transmit on SSB.  The KAT3 indicates a 1.0:1 match, but the when I transmit the swr meter is high and I get the high swr message on the screen.  If I turn it down to 5 watts and send a tone with Digipan, the swr is fine, but turn it up to 100 watts and the swr is back up.  Nothing obvious has changed, the antenna is 2:1 on my analyzer with no tuner.  If I bypass the antenna tuner, the bar graph meter on the K3 shows about 2:1.  But if I switch in the KAT3 and tune, it indicates 1.0:1 but when I transmit it's high.  I've swapped coax jumpers between the radio and the antenna with no difference.  Thanks for any suggestions.
