Started firmware download. Got message that MSU failed. The utility attempted to reload the firmware. Unsuccessful again. So I closed the utility, downloaded proper version. But now K-3 will not turn on completely. At power on, transmit light blinks continuously (red!) and message on screen MCU LD. But there is no communication through the com port, although K-3 Utility shows comport open. I cannot turn K-3 off with power switch. I had to resort to unplugging at AC outlet. Tried to reinitialize parameters, but unable to do so because even though I'm holding down the SHIFT/LO knob, when I turn power on, the blinking transmit light occurs and MCU LD message appears. The utility does show comport open, but unable to connect. Help greatly appreciated. 73, Art KZ5D ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
