To ensure the operational readiness of all HF equipment and the competence of HF radio operators (usually U.S. direct hire (USDH) staff in the Information Programs Center (IPC)), posts must test HF radio equipment weekly and officially record the results as directed in the NOI. Consult RIMC if equipment fails or if personnel require additional training. IPC personnel should maintain documentation of the testing schedule and unique post circumstances affecting radio operations.
b. Department organizations that have off-site HF equipment or HF mobile radios must test them on a monthly basis.

5 FAH-2 H-725 REPORTING REQUIREMENTS
(CT:TEL-100; 06-04-2024)
The Information Programs Center (IPC) staff of each HF network control station performs weekly testing and records the results of each subscriber station and any problems experienced. Network control stations record results on the HF Reporting Form available on DT’s Crisis & Contingency Communications Reporting Management Portal. Test results are viewed by senior DT leadership and RIMCs to ensure network control stations conduct weekly testing and identify ongoing issues and/or trends. Contact the RPB or RIMC for guidance regarding the HF test program.
