200mW making it (10MHz, 1/4 wave vertical, WSPR, daughter's callsign) comfortably across at -25dB/2500Hz to Hawai'i at 05:22UT this morning.

Given the detection limit is -34dB for WSPR, as little as 25mW ought to just make it.

If I was at the beach, much less power would make it; I've crossed the Atlantic on 50 microwatts in past tests.

@GreyGhost You wouldn't believe the number of angry old men (nowhere near the sea) who will argue until they have a heart attack that, somehow, water doesn't make so much difference and that WSPR isn't 'real radio' anyway. 🙄

@MW1CFN oh I know. Humans love to argue. 😉
