[Elecraft] K3, KPA500 KAT500 Firmware Upgrades

[Larry Libsch]

Group -

        My K3, KPA500, KAT500, two USB soundcards and an SDR are all 
cabled together and playing well. I would like to upgrade the firmware 
in all 3  K line devices.  Is it necessary to completely or partially 
remove cables before attaching my computer via USB - serial port cable 
to each K line device in turn and doing its firmware update? Removing 
and reassembling the cables is possible, but not trivial.

                                 K4KGG, Larry
