As you can see in Polex Technology photo [at the top of this page], they only had an Elecraft KX3, a laptop, and their Polar Explorer on the table.<\/p>\n<p>So what is the Polar Explorer exactly?<\/p>\n<p>At first blush, the Polar Explorer looks like a 500 watt amplifier, but then you notice that it has both a microphone and key connected directly to it. The Polar Explorer also has a color backlit screen\/display&#8211;and the one at the 2019 Hamention was attached to an <a href=\"https:\/\/swling.com\/blog\/2013\/07\/a-review-of-the-elecraft-kx3-a-world-class-transceiver-superb-shortwave-receiver\/\">Elecraft KX3<\/a> QRP Transceiver.<\/p>\n<p>Turns out the Polar Explorer isn&#8217;t an amplifier at all&#8211;it&#8217;s an external 500 watt transmitter. As noted on <a href=\"https:\/\/www.polex-tech.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">the Polar Explorer website<\/a>:<\/p>\n<blockquote><p>The Polar Explorer is a breakthrough in transmitter design which brings much higher efficiency to SSB and CW transmitters. Most &#8216;linear&#8217; amplifiers run at around 55 to 60% efficiency, which means a lot of extra power supply capacity is required, along with extra cooling and dissipation capacity. By increasing efficiency, The Polar Explorer significantly reduces power supply requirements as well as cooling. From this, significant reductions in cost, size, and weight can be realized for a given power output level.<\/p>\n<p>[&#8230;]The Polar Explorer interfaces to your transceiver using the CAT interface to obtain frequency and mode information. It automatically follows the transceiver as you QSY or change modes. Your transceiver never transmits; The Polar Explorer handles those functions, and includes a T\/R relay to protect your transceiver.<\/p><\/blockquote>\n<p>By connecting your transceiver to the Polar Explorer, you&#8217;re essentially bypassing and delegating the transmitter portion of your transceiver to it. Your transceiver still provides the receiver section and full interface\/user experience&#8211;the Polar Explorer provides the muscle.<\/p>\n<p><a href=\"https:\/\/swling.com\/blog\/wp-content\/uploads\/2019\/06\/Polar-Explorer-Internal.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-38144\" src=\"https:\/\/swling.com\/blog\/wp-content\/uploads\/2019\/06\/Polar-Explorer-Internal.jpg\" alt=\"\" width=\"800\" height=\"600\" srcset=\"https:\/\/swling.com\/blog\/wp-content\/uploads\/2019\/06\/Polar-Explorer-Internal.jpg 800w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2019\/06\/Polar-Explorer-Internal-300x225.jpg 300w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2019\/06\/Polar-Explorer-Internal-768x576.jpg 768w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2019\/06\/Polar-Explorer-Internal-624x468.jpg 624w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\n<p>Note that the Polar Explorer is a project <em>in development<\/em>.
