It is a signal processing technology used to send and receive information over both FM and AM radio waves. Digital Modulation is used in almost all devices that perform some type of communication -\u00a0everything from cell phones to Hidden Fences.\u00a0<strong>All underground fences use Digital Modulation<\/strong>.<\/p>\n                <!--noptimize-->\n                <!--\/noptimize-->\n      <\/div>\n    <\/div>\n  \n\n  \n\n    \n\n  \n\n  <\/div>\n<\/div><\/div><div id=\"panel-4108-0-0-1\" class=\"so-panel widget widget_wysiwyg-panel panel-last-child\" data-index=\"1\" ><div\n\t\t\t\n\t\t\tclass=\"so-widget-wysiwyg-panel so-widget-wysiwyg-panel-base\"\n\t\t\t\n\t\t>\n<div class=\"background-color-wrapper bg-color-white\"><\/div>\n<div class=\"pc-RbbilIqZIT wysiwyg-panel-container container has-background-wrapper no-padding-top padding-bottom \">\n\n  \n\n      <div class=\"row content one-col\">\n      <div class=\"col col-sm-12\">\n        <h3>The Real Difference in Hidden Underground Fences is FM vs AM<\/h3>\n<p>What\u2019s the difference? FM radio signals are \u2018cleaner\u2019 and more secure than AM signals. A good example is FM radio stations (no static) compared to AM radio stations (lots of static). That is the reason that fire\/police and emergency responders typically communicate over FM channels<\/p>\n<p>A simple explanation of the difference between FM and AM signals is:<\/p>\n<ul>\n<li>FM frequencies use a \"continuous\" radio signal.<\/li>\n<li>AM frequencies switch \"on\" and \"off\" during transmission.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-2946\" style=\"max-width: 500px;width: 100%;height: auto\" loading=\"lazy\" src=\"http:\/\/fpddev.com\/master-dealer-template\/wp-content\/uploads\/2019\/09\/fm-signal-animation-1x-2.gif\" alt=\"\" width=\"500\" height=\"281\" \/><\/p>\n<p>Because the FM signal is \u201ccontinuous\u201d, FM frequencies are less susceptible to interference from other signals, so the fence collar is less likely to activate in unexpected locations. This makes FM systems safer for your pet.<\/p>\n<p>When the AM signal is \"off\", it is open to interference from other AM radio signals, such as those that come from common household electronic devices.\u00a0From a hidden fence perspective, this is important because these random signals may trigger the fence collar. When the collar activates where it is not expected, it can confuse (and frighten) your pet.<\/p>\n<p><strong>Our patented SafeLink\u00ae FM signal makes DogWatch\u00ae Hidden Fences the SAFEST system for your pet.<\/strong><\/p>\n<p>ALL hidden underground fences use Digital Modulation (DM).
