You can tell it&#8217;s someone talking but of course you can&#8217;t make out what they&#8217;re saying. Here lately, I&#8217;ve heard this all across both the 20 AND 40 meter bands. It&#8217;s overwhelming all signals with an S9 level that sometimes peaks at +20. I&#8217;ve tuned up and down 20, 40, 75 meters, but I haven&#8217;t found the culprit yet. It&#8217;s unpredictable when it will happen. It could be 7 am or 10 pm. Whoever it is, they&#8217;re quite long-winded.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">My first theory is another ham who lives up the street from me. He&#8217;s only 2 blocks away. If he&#8217;s running high power, would that cause this de-sense?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I can&#8217;t image a cordless telephone being at fault since they&#8217;re all above 900 MHz nowadays. Nobody uses CB anymore so I can&#8217;t blame them, either.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I might go visit the ham up the street, see if I can rule him out. Who knows, maybe he&#8217;s plagued by the same interference. Until I get to the source of it, the best I can do is just operate around someone else&#8217;s schedule.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You know how it sounds when a station on HF is just a few kHz away?
