”

This page contains information and reception reports for the IRTS 144MHz two-way Trans-Atlantic Beacon operated on behalf of the Irish Radio Transmitters Society (IRTS) by EI8JK, Tony Baldwin. The beacon transmits on 144.488MHz every even minute and listens for replies from across the Atlantic (and elsewhere) on 144.155MHz every odd minute. The beacon changes to FSK441 during scheduled meteor showers. The beacon equipment consists of 4 five element LFA-Q antennas (22.24dBi) that are beaming due West. The beacon transmits with a power of 75 watts. The software and control system is Joe Taylor K1JT’s WSJT software running on Windows 7.

Location: Kilcrohane, Sheeps Head, Co. Cork, Ireland. IO51dn. Latitude: 51 33.70’N, Longitude: 009 42.60’W. Kilcrohane is about half way out the Sheeps Head Penninsula – a long, rugged headland that extends out into the Atlantic Ocean off Ireland’s South West Coast. Sheeps Head is on the route of Ireland’s Wild Atlantic Way.
