I called Brian (WB6RQN/Aeronautical Mobile) via HF ham radio using ALE (Automatic Link Establishment) and we linked on 14346 kHz USB in the 20 meter band. ALE is similar to HF Selcall. He answered the call and immediately responded on voice with his callsign. It was about 9PM Pacific Time here in California. He was flying over the Pacific Ocean at about FL210 between Tonga and American Samoa. We talked for about 30 minutes on SSB voice, until around sunset at his position, when his signal started to fade.

My HF radio station (KQ6XA) location is Silicon Valley, California. The equipment in use for this radio contact was:
Transceiver: Icom IC-F8101, Power: 125 Watts, Antenna: vertical, with the top at 36 feet.

Radio great circle path distance: approximately 4500 Nautical Miles (8330 km) or (5180 miles), 

The actual radio path distance was much longer, via multiple hops bouncing off the ionosphere and the surface of the Pacific Ocean.

Wouldn't that be 8:45 pm Sunday local time instead of last night (Saturday) since he hasn't crossed the international date line yet?

The International Date Line passes between Samoa and American Samoa.

American Samoa is on the east (American) side of the dateline. 

Brian crossed the dateline "eastward" on his way from New Zealand to American Samoa.

He will cross it 2 more times:

1. Dateline crossing "westward" into Kiribati area, on his flight tomorrow.

2. Dateline crossing "eastward" out of Kirabati area on his way over Howland Island to Hawaii.

If he crossed it enough times could he make it back for Oshkosh .. lol?
