[Elecraft] [K3] Minor irritation with K3 Firmware Loader, Version 1.0.11.21

[Dick Dievendorff]

Please don't rename firmware files.  There's a consistency check that
compares the internal version number and the version number implied by the
filename that will be disrupted if you rename the files.  Firmware load
verification will fail if you do this.

Instead, clear the "Copy Latest Files from Elecraft" check box, create a
folder with the files you want to load, navigate to that folder, and that is
the "available" version column. 

You can load back-level files by using the View Menu's Advanced Option to
expose a column of per-processor check boxes.  Select the MCU and DSP1 check
boxes and click "Send Checked Items" button.

Be careful which files you load together.  MCU and DSP1 versions are
sometimes released together with interdependencies.  Their version numbers
do not show that dependency. Thus, MCU 01.39 does not necessarily correspond
to DSP 01.39.

In general, you should be moving forward, and the options to go backward
were deemphasized in an attempt to make it as straightforward as possible to
go forward to newer (and presumably better) firmware revisions.

Hi Ed,

I did it with a file rename...
The Software offers only the newest file to upload to the receiver.

Download all available files from the FTP site if you don't have them
already on your pc.
Restart the software and configure the 'advanced mode'  (view menu...).

After uploading the firmware you can just rename the file to its original
name.
The software will offer the newest version as before...

Didn't find any information about concernes to switch between the different
versions.
Especially the dependencies between the MCU and DSP versions is not clear.

Maybe Elecraft can give us some information ... ?

The problem I have with the download utility is that it doesn't allow you to
revert to an older version of the firmware.  Maybe you can rename the file,
but then you probably will risk not being able to load a later version of
that name.  Does anyone know how to revert to a previous firmware load?
