Re: 100th Anniversary of Transatlantic Tests: Special event station using a 1921 replica transmitter? 12/11/2021.

"Schedule: Transmissions start on December 11, 2021, on 1.820 MHz, +/-, at 1800 EST or 2300 UTC, then every 15 minutes thereafter for a total of five hours thusly; 1815, 1830, 1845, 1900, 1915, 1930, 1945, 2000, 2015, 2030, 2045, 2100, 2115, 2130, 2145, 2200, 2215, 2230 and the last transmission at 2245 EST."

Well, they mentioned both, EST and UTC, times. I had to work through it, so I missed it.
