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

[Lyle Johnson]

Hello Nate!

The K3 Utility version that should be used is one that explicitly 
supports the "b" files which are used for K3 FP boards that use a 
different LCD controller than we have used in the past.  In the case of 
a Windows PC, that is version 1.13.4.15 available on the website.  Mac 
and Linux Utilities to support this version will be released soon.

Meanwhile, if you choose to load the K3 Beta and not use a Windows PC to 
do it, it seems you will need to delete the "b" file from your directory 
after you unzip it.

Thank you for your report on this behavior!

73,
