I was in Baltinglass on the border of County Wicklow and County Kildare. If I had intentionally looked for it I may have found it, but a scan skipped by it and it wasn't a comprehensive tune. Wife and father-in-law were in tow at times, if you know what I mean 😉
Surprised you didn't hear Energy on 1440 khz from South Dublin. It runs at least 400 watts and is on every weekend and has been since 2004. I would imagine it would be audible in Wicklow town and county.
