Hamclock frontend image updates

The final original Hamclock from ClearSkyInstitute was version 4.22 and this is the version that everyone has installed. Dave N9DK / OHB will continue to develop the client with improvements and maintenance. If you you wish to keep up-to-date with the frontend, it is quite simple to do so.

Firstly go to the Hamclock Client releases page at https://github.com/komacke/hamclock/tree/main

Click 'Tags' to open a list of versions. Select the latest and Downloads. Pick HamClock Source Zip with version and get the zip. It is best to use your web browser on the Pi so that the file downloads directly. This latest client version can be used to overwrite an existing Hamclock or used for a fresh install.

Unzip it to get the ESPHamClock folder. If you want to amend the Kp_Interval value, follow the instructions on the Home page. After, right-click the folder and select Open in Terminal as before. The make commands are used in turn as previously described.

This new installation will offer new subsequent versions to your Hamclock and uses the standard HC self-upgrade method.

A pre-existing desktop icon pointed at OHB will work with the new installation as, of course, will a hosts file amendment.
