FM radio station in Iceland on 88 MHz is heard in the USA (3900kms) - 8th July 2021

Thurs 8th July 2021: Over the last few weeks, there have been some remarkable openings on the FM band in the North Atlantic. Links to post HERE

On the 8th of July, there was yet another opening in the North Atlantic when a FM radio station on 88 MHz in Iceland was heard by four individuals in the USA. Three in the state of Massachusetts and one in New Jersey.

21:53 UTC 88.00 MHz RÚV Rás 1, Stykkishólmsbær/Stykkishólmur-símstöð (3,945 kms) 18kW (Bryce Foster (K4NBF), Mashpee, MA, USA)

22:06 UTC  88.00 MHz RÚV Rás 1, Stykkishólmsbær/Stykkishólmur-símstöð (3,921 kms) 18 kW (Jeff Lehmann, Rockland, MA, USA)

The individuals concerned were... Bryce Foster, K4NBF (MA), Jeff ?? (MA), Keith McGinnis (MA) and Nick Langan (NJ).

As can be seen above, the distance was just over 3,900 kms. The likely propagation mode was double hop Sporadic-E (1950 kms x 2). 

However, that part of the Mesosphere where Noctilucent Clouds are found has been shown to reflect radio signals and that can't be ruled out.

One hop Sporadic-E reception on Band 2 over southern latitudes for example in Europe or the USA is really nothing special. When we start getting up into the Arctic regions, it's less obvious what the cause is for long distance VHF signals and that's why these reports are of interest.
