  • EI4HQ NAVTEX Spectrograms for 2026-06 (June)

    , ,

    Here’s you’ll find links to a daily spectrogram for the NAVTEX MW sub-band, recorded at Cobh, Cork Harbour, Ireland, IO51uu during June 2026. I started saving these first, on the 7th of June 2026. Each spectrogram covers a 16h 44m period, that being the length of the longest night of the year here, with 15m…

  • The End Fed Half Wave Antenna

    My trusty 20M GP antenna, is a much-loved and proven favourite for operations away from the home QTH. Recent experience has made clear however that It’s not ideal for POTA, SOTA and other short term /P activations. It’s relatively heavy at about 2kgs, and it takes about 15 minutes to set up.

    I had so much fun the previous day and as I was passing nearby, I couldn’t pass up the opportunity to also activate IE-0073, Ballyteigue Nature Reserve near Lisdoonvarna in The Burren. A very beautiful and secluded spot, it was a wonderful place to spend some time. The DX wasn’t too bad either.
