First activation abroad and… first failed activation with less than the 4 QSOs needed to validate it 
In a morning that started rainy but with a great Irish breakfast prepared by Sean from the B&B begins the walk to the summit of only 171m, (I’ve received a funny badget with sympathy for this: Low rider 
)
Almost on the first call I received the answer from @EI6JHB with a signal of 31, perhaps a foretelling that it would be my only contact of the day.
After 40 fruitless minutes I decide to descend as the cliff path and Ye Olde Hurdy Gurdy Museum of Vintage Radio in Martello Tower were waiting to enhance the day.
I have to apologize to @EI0MAR because I got (radio illegaly) from the guide an QSL from this amateur radio colleague. I hope to get another one by making QSO someday!!
Many thanks to everyone on this thread who made it possible to complete that wonderful day of radio in Howth.
