We were delighted to welcome Paul Gacek W6PNG and his XYL from Laguna Beach, CA as the speaker at our meeting on 28th March 2018.  Paul is a SOTA friend of Andy MM0FMF to whom our thanks for arranging this talk. Originally from London, and now splitting his time between CA and Berwick-on-Tweed, Paul talked about "Wilderness radio in the Western US with an emphasis more on photos than any kind of tutorial" and showed many photos of the beautiful places he has operated from.
