FM radio station on 91 MHz in Greenland is heard in Ireland - 19th May 2024


On the 19th of May 2024, FMDXer Paul Logan in the north-west of Ireland reported reception of a radio station in Greenland on 91.0 MHz.

UTC QRG ITU Station, location Details Distance km kW ERP Pol
2044 91.00 GRL Kalaallit Nunaata Radioa, Niaqernaartik/KTYC (Kap Tycho Brahe) 2095 0.1 v

The radio is located on the east coast of Greenland, has an effective radiated power of just 100-watts and runs vertical polarisation. Paul logged it at 20:44 UTC.

A 52-second audio file from the reception can be heard HERE

The distance to Paul's location in Lisnaskea, Co Fermanagh is 2095kms and the propagation mode was Sporadic-E (Sp-E). While the distance is well within the maximum for a single hop of Sporadic-E, it's always interesting when a FM station in Greenland is heard in Europe.

Greenland is technically part of North America and hints hopefully at maybe some very rare trans-Atlantic signals on the FM band in the weeks ahead.

FM radio station on 88.5 MHz in Greenland is heard in Ireland - 21st June 2021


Monday 21st June 2021: This was an exceptional day for Sporadic-E propagation with FM radio stations on the 88-108 MHz band in Greenland and Canada being heard across the North Atlantic in Ireland.

In this post, we'll look at the reception of the Greenlandic station.

Paul Logan near Enniskillen in the north of Ireland is an avid DX-er and has logged hundreds of radio stations on the 88-108 MHz FM band over a period of 20+ years.

On the 21st of June, he managed to hear the KNR radio station from Greenland on 88.5 MHz for the best part of an hour from 13:00 to 14:00 UTC. An audio recording is shown below...

Paul also listened to the online feed and it matched what he was hearing.

For the reception, Paul was using a ELAD FDM S2 SDR receiver with a Band 2 9-element Yagi 8m above ground level.

At the moment, Paul is trying to ascertain where the exact location of the transmitter in Greenland.

Analysis: It's very likely that this reception was via one hop Sporadic-E as the map at the top of the post suggests. The maximum distance for a single Sporadic-E hop is in the region of 2300kms and the southern part of Greenland seems to be just about within range of Paul Logan's location.

What is highly unusual about this reception report is getting Sporadic-E at 88.5 MHz from so far north in the North Atlantic.

It raises the question: If an 88 MHz signal can get from Greenland to Ireland then could a 144 MHz on a more southerly path head from say the south of Ireland the UK / NW France across towards Newfoundland and Nova Scotia?? 

Could one Sporadic-E hop with a tropo extension reach across the North Atlantic on 144 MHz???
