Ron, W7HD, points out that downloading the KD8CEC 1.072 can be a problem
because version 1.072 does not appear in the list.
It is necessary to click on the Branch button,
then use your mouse wheel to
scroll down until the version1.072 is revealed.
Best to All,
See below for an excerpt:
Download the CECFW source code from github
For this example we will be using version 1.072.
Click the “Branch” button to select version 1.072, then click “Clone or download” and click “Download ZIP”. Unzip the downloaded file and make a note of the folder location, or move the unzipped directory into your arduino sketch folder.
