My first time FW upgrade failed too. The problem? I use Router a virtual port defining piece of software microHAM uses for their product's interfaces to such things as the microKEYER II. In their manual is a warning in Yellow to not perform FW upgrades via the microKEYER II interface which uses a port in their Router. Indeed - don't do it. microHAM support told me the problem is the Router is continually polling the radio and interferes with the download. While all other features and functions of Elecraft's Utility and Memory Editor works fine, the FW download does not. I have a desktop PC with no serial ports only lots of USB. Elecraft sells a very nice serial RS-232 to USB adapter cable with FTDI chip. Using the FTDI driver to define a separate USB port as a COM port works well. I have also used Prolific drivers for converter cables using Prolific protocol without any attention. Both work really well. It will/would be nice to have Elecraft provide a USB port in the radio like some other manufacturers. ICOM for instance - absolutely trouble free and simple. Copy a file to a thumb drive and stick it in the radio's USB jack and press Upload. Also in the case of ICOM's 7800 and 7700, you can plug a USB keyboard in and run RTTY or PSK - from the keyboard. No paddle needed. Anyway - microHAM has excellent software and hardware but as they say, do not attempt to download FW into any radio using an interface with something like microKEYER II. So when I want to perform a FW update I unplug the microKEYER II originating DB-9 from the K3 and plug in the separate USB/RS232 cable and perform the update. 73, Bob - W6OPO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
