While the initial project seems primarily be for internal use in South Africa, ZS6YZ also raises the possibility of testing other very long distance paths as well.
In the past when only CW and SSB was used on the 2-metre band, beacons on CW would often appear first during a tropo opening. The beacon was then spotted on the cluster and stations were alerted about the opening.
Now, CW only beacons are of limited use with weak digital signals like FT8 making an appearance long before the CW signals can be heard. In todays world where computers can just sit and listen for signals 24 hours a day, a modern mixed mode beacon using CW and a digital mode like PI4 makes a lot more sense.
The video is just over 40 minutes long and it can be seen below...
