[Elecraft] K3 Beta Firmware Rev. 3.59: Misc. improvements

[Guy Olinger K2AV]

My take on this would be that although the PC copy of the file is
fine, that Winders is glitching the send from the PC to the K3 by not
paying rapt attention to the one and only timing dependent app running
at the time, and somehow dropping stuff.  The procedure previously
outlined has kept firmware loads pristine.
