Hi

There are multiple European chains running that can be picked up from the
US. They all are in the skywave zone distance wise.

Do you have any idea of the transmitter power/antenna gain?

The relatively low power of the UK 60 kHz is strong enough to interfere w/
WWVB in MA, so I'm wondering if the UK eLORAN might be usably strong.
