WWV is\u00a0<em>not<\/em> officially open to tours, so this was a particular honor for me. And this\u00a0was an especially fun pilgrimage, as WWV was most likely the first shortwave broadcast I ever heard: \u00a0<a href=\"http:\/\/swling.com\/About.htm\">as I&#8217;ve previously noted<\/a>, when I was a kid\u00a0my father used to set his watch to WWV every Sunday morning. \u00a0Now I&#8217;ve seen firsthand\u00a0where that\u00a0famous<em> tock, tock <\/em>(and accompanying characteristic tones) originate.<\/p>\n<p>When I return home from my extended travels, I&#8217;ll sort through the photos I took at WWV and WWVB, and\u00a0post them here on the <em>SWLing Post.<\/em><\/p>\n<h2>Recording WWV<\/h2>\n<p>In the meantime, I have a few recordings to share with those who are interested in this mecca of chronology. \u00a0Before leaving WWV, I pulled out my Tecsun PL-380 and my Zoom H2N digital recorder, and recorded <em>all<\/em>\u00a0the WWV broadcast frequencies. I captured their 2.5, 5, 10, 15, 20 and even their recently reactivated 25 MHz signals.<\/p>\n<p>I made these recordings in the conference\u00a0room at WWVB broadcast house. As you can imagine, it was simply not at all necessary to extend the telescopic antenna. In fact, the signal was so strong, you&#8217;ll hear a slight amount of distortion in the voice audio.<\/p>\n<p><a href=\"http:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/08\/TecsunPL380WWVB.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-10665\" src=\"http:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/08\/TecsunPL380WWVB.jpg\" alt=\"TecsunPL380WWVB\" width=\"640\" height=\"583\" srcset=\"https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/08\/TecsunPL380WWVB.jpg 640w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/08\/TecsunPL380WWVB-300x273.jpg 300w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/08\/TecsunPL380WWVB-100x91.jpg 100w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<p>Below, you can listen to the recordings of each frequency via the embedded player (click on the title to download the audio).
