[Elecraft] Failed K3 Firmware update DSP1

[Don Wilhelm]

Matthew,

You should not have to do incremental firmware updates.
Keep the 2.19 firmware files "just in case", but delete the latest 
firmware files from the folder where you have the firmware stored on 
your computer in case the copies you have are corrupt.

Open K3 Utility (make sure it is the latest), and then "Get files from 
Elecraft" to download the latest production firmware.

Once you have those files on your computer, click the "Send all files to 
the K3" and it should update with no problem.

73,
Don W3FPR
