Update March 19, 2023: Jacek arrived Calayan island OC-092 yesterday (March 18) and has already been QRV on 6m. Today, he’ll be on HF.

Update March 13, 2023: DU1/SP5APW will go QRT soon (approx 0800-0900z) as Jacek needs to pack all stuff and to be ready to get up very early on Wednesday for the ferry.

Update February 4, 2023: To avoid problems during FT8 operation, DU1/SP5APW  will be  the callsign that Jacek will be using from both islands.

Update January 28, 2023: He will use DU1/SP5APW/p from Marinduque Island (OC-244) on 9-14 March, and DU1/SP5APW from  Calayan Island (OC-092) on 18-26 March.  He will operate SSB and FT8 on  40-10 metres, and digital on 6 metres.

DU1/SP5APW will be active from OC-092 and OC-244, sometime in March 2023.
