[Elecraft] Kat500 Firmware

[Lyn Norstad]

The KAT500 Utility software is v1.21.9.15.  Use it to download and install the KAT500 v02.05 firmware.

Have you tried under Windows?

It's always worked perfectly for me.

Hi,
	Having difficulty loading latest version of the Kat500 utility.  The version I have is 01.75, the utility indicates that 2.05 is available.  However the new version does not load but the message “ Input hex file is corrupt, check sum is not zero”

I have the same issue attempting to load a Mac and Linux.

Perhaps 2.05 is not available?  Or is there a fix I am not aware of, or perhaps it is not necessary to upgrade?

Thank you for your interest. Help would be appreciated.

Best
