Just started happening today. MCU 3.80. I tap power (to shut it off, just as I've always done) The LCD goes all-orange, no segments. The Rx goes off. If I power cycle the power-supply the K3 comes back on in normal operation. Strange. -- Jeff Wandling DE W7BRS K3 #2105 http://w7brs.com/k3 jdw at w7brs.com
