via the ARRL: Philippines Ham Emergency Radio Operations Network Bracing for Effects of Super Typhoon

According to information received from International Amateur Radio Union Region 3 (IARU-R3), the Philippine Amateur Radio Association’s Ham Emergency Radio Operations (HERO) network activated on July 7 at 2145 UTC, as fears arose that super typhoon Nepartak could amplify the effects of the southwest monsoon. Heavy rains in some areas caused schools to preemptively cancel classes.

HERO operator DV7DRP opened the net on 7095 kHz at 2300 UTC on July 7 with relay net controls DU1IVT, DU7DUG, and DU1EQ. Propagation necessitated relays and a handoff of net control duties to DU1VHY.
