The Galway Radio Experimenters Club

 My old friend Mike EI0CL used to remind me that hams in Ireland are
granted not just an amateur radio license, but an amateur radio
experimenter's license, with an emphasis on experimentation. I think we can
see that emphasis in the newsletter of the club.  It has a remarkably high level of technical content.  Check it out, and look at more information on the club: https://www.galwayradio.com/
