Wednesday 21st July 2021: At the start of July, FM radio stations on the Azores were heard in the USA. On the 21st, the North Atlantic path opened again with FM stations being heard in Newfoundland and Cape Cod, MA.
This is a log of what was heard by Larry Horlick (VO1FOG) in Newfoundland and Bryce Foster in the US...

Propagation Mode: It looks very likely that this was a case of single and double hop Sporadic-E again.
The distance from the Azores to Newfoundland is in the region of 2200-2500kms and this was most likely one hop Sporadic-E with a small tropo extension.
The distance from the Azores to Cape Cod in the US is 3830kms and this was very likely to be double hop Sporadic-E.
It's interesting to see that the path from Newfoundland to Bermuda was open at 21:00 UTC which suggests the location of one of the Sporadic-E clouds.
