Irish Trans-Atlantic 144 MHz beacon EI2DKH stops transmitting - May 2022

It was announced this week that the Irish trans-Atlantic 144 MHz beacon EI2DKH has ceased transmissions.

Operated on behalf of the Irish Radio Transmitters Society (IRTS) by Tony Baldwin, EI8JK, the EI2DKH beacon transmitted JT65B on 144.488 MHz with a CW identification on every even minute.

The beacon was established in early 2015 with the hope that the 2m signal would be heard across the North Atlantic in either Canada or the United States.

The beacon’s power output was 75 W to an array of 5 element Yagis at 60 meters above mean sea level and beaming due west from Sheeps Head in IO51dn.

As can be seen from the map, this was in the far south-west of Ireland and just over 3,000 kms from Newfoundland, Canada.

In its seven years of operating, there were no 2m reports from across the Atlantic.

In a statement on the 5th of May 2022, the beacon keeper Tony, EI8JK wrote...

"It has been pointed out that my EI2DKH beacon is perhaps not the best site. That coupled with the electricity cost for running it 24/7, I have decided to not run the Trans-Atlantic beacon this year.

If there is an EI/GI amateur with a good site on the west coast who would like to take it over, I would willingly supply the 4 antennas, splitter and pre-amp.

Sorry to disappoint.

73, Tony, EI8JK."

This project might be of interest to any individual or group who have access to a site which is near the western seaboard of Ireland and has an extremely low horizon to the west-north-west.

EI2DKH - The 144 MHz trans-Atlantic beacon


The EI2DKH beacon in the south-west of Ireland is now running 24/7 beaming across the Atlantic hoping to make contact with North America. 

The station run by Tony EI8JK transmitting Q65 (60 sec, sub mode C) with CW ID every even minute on 144.488 MHz with audio frequency of 1500 Hz and it receives Q65 every odd minute on 144.178 MHz with audio frequency of 1500 Hz.

The beacon runs 100-watts into 4 x 5-element LFA-Q antennas beaming 270 degrees.

The beacon locator IO51DO90CL and the site is about 40 metres above sea level.

Analysis... The beacon site is somewhat obstructed to the west with a 220m metre hill about 2.5kms away (3.2 deg elevation at 279 deg) which will prove to be a challenge.
