KUAM 630 Guam returning to air, weakened from new antenna site:
According to this, KUAM ceased broadcasting 630 on May 1, 2020. It would continue on FM, streaming. No explanation of why. Station 2) was deleted from WRTH 2021 but the 2) reference remains.
Now, an FCC application to move its transmitter site has been approved. The old site was leased on a month-to-month basis and could not be relied upon.
The new site is at the KSDA shortwave! facility with what appears to be a temporary antenna design, to be at reduced power but sufficient to cover the island.
FCC AM Query now shows the original 10 kW info and, as applications, for the new site at 2.5 kW:

Here is the letter granting STA only until September 20, 2021:

The engineering statement with all the details, including diagrams of the antenna, maps of old and new coverage:

A month earlier, in February, KUAM applied to change from commercial to non commercial, and with a new licensee name, Good News Broadcasting, i.e. religious. It is not clear how closely or what relationship it now have to Adventist World Radio. Its old brand was “Isla 63“ music, by Pacific Telestations.

Expect the new facility to go on the 630 air once the license transfer be completed, with weaker signal and new format.
