Salt Water Daytime DX from the Philippines-- 5 kW at 683 miles

Mark Connelly's doctrine of getting right up to the salt water edge was proven again during file review of daytime DXing in Macau-- a strange gambling enclave located 50 miles west of Hong Kong.

On 720 kHz a weak Tagalog station was received on the Macau waterfront all by itself in bright daylight around 2 PM local time, although Macau is over 500 miles away from any part of the Philippines. To make the story even stranger, the receiver was a CC Skywave Ultralight-- although it did have a 7.5 inch loopstick going for it.

The weakfish signal was recorded and forgotten until this morning, when a dubious attempt was made to dig out any identifying clues which might determine which one of the three 720 kHz Filipino stations showed up at such long range. After listening to the weakfish recording about 10 times I was amazed to determine an energetic "Radio Bombo" ID by the Tagalog-speaking lady at 23 seconds into the recording, which matched the network ID description of 720-DZSO, a 5 kW station in San Fernando, Luzon, Philippines-- at 683 salt water miles (1,099 km) in bright daylight. How can you get luckier than that?

Daytime DXing at the salt water edge during the Hong Kong trip proved to be essential in sorting out the maze of unfamiliar signals, providing not only some awesome Taiwan recordings but several 500+ mile Philippine stations making the trip in bright daylight. Receiving so much international DX in bright daylight was a bizarre feeling, with even 549-VOV2 showing up as a crowning touch at HK's Cape D'Aguilar (according to Alan Davies).
