[Elecraft] [K3] Possible bad file in 4.67 ZIP archive

[Nate Bargmann]

Checking on the available K3 firmware this morning, I saw that a Beta
4.67 is available.  After downloading and attempting the update, the MCU
load failed (first time for me).  After a few more tries and failures I
successfully loaded MCU 4.61, FPF 1.15, and DSP1 2.81 so I knew the K3
was fine.  :-)

Watching the K3 Utility dialog boxes I saw that file 'hmcu0467b.hex' was
being loaded.  Looking in the directory, I saw that file 'hmcu0467.hex'
also was present and 17 minutes newer.  "Hmmmm", sez I, so after
deleting 'hmcu0467b.hex', MCU 4.67, FPF 1.15, and DSP1 2.81 firmware
files all loaded correctly.

I am using the "Elecraft K3 Utility for Linux Version 1.12.9.22", if
that matters.

As the file size between 'hmcu0467b.hex' and 'hmcu0467.hex' is the same
(but the "diff" utility shows a lot of differences), the utility
apparently chooses 'hmcu0467b.hex' by determining that the extra
character makes it a later file.  In this particular case, it happens to
be earlier and this K3, S/N 4762, didn't like it at all.

On the plus side, I now know how to recover from a bad MCU load, the
first time this has happened to me in over 2 1/2 years of owning my K3.
