The MilliWatter Extreme is an RF-switched transmitter-attenuator that opens up the world below 1 Watt. These low power levels are not available for many transceivers. Few power meters are accurate at these levels either so the MW Extreme opens up a new world of challenge; a world that is inaccessible for many transceivers used for QRP.<\/p>\n<p style=\"text-align: justify;\">Because the MW Extreme&#8217;s attenuators are RF-switched, you retain full receiver performance &#8211; essential for the higher HF bands. The MW Extreme has an adjustable hang-delay time for convenient use on different modes.<\/p>\n<p style=\"text-align: justify;\">Using the MWEXTREME is much more convenient than using conventional attenuators, especially for the multi-band MilliWatter who needs to tune an antenna on band changes. With the MilliWatter Extreme you can tune on full power at the flick of a switch and then immediately join the fun on QRPp.<\/p>\n<p style=\"text-align: justify;\">The MilliWatter Extreme gives you two accurate new power levels: 1\/10th power and 1\/50th power. We spent a lot of time designing the attenuators to give exceptional performance across the entire HF band.<\/p>\n<p style=\"text-align: justify;\">The following examples show the power levels the MWEXTREME opens up for you:<\/p>\n<ul style=\"text-align: justify;\">\n<li>Input power 5 Watts, output (low) 500 mW, output (extreme) 100 mW.<\/li>\n<li>Input power 2 Watts, output (low) 200 mW, output (extreme) 40 mW.<\/li>\n<li>Input power 1 Watts, output (low) 100 mW, output (extreme) 20 mW.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">You will be amazed at what can be done with such extreme QRP. Set yourself some new challenges, worked all states or worked all continents on 100mW perhaps?<\/p>\n<p style=\"text-align: justify;\">The MilliWatter Extreme gives you three convenient power levels at the touch of a switch &#8220;full&#8221;, low and extreme.<\/p>\n<p style=\"text-align: justify;\">The MilliWatter Extreme is also great for WSPR and datamode experiments. It can also be used to reduce power for transverter drive.<\/p>\n<p style=\"text-align: justify;\"><a href=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2015\/01\/mwe-setup.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-42465 size-full\" src=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2015\/01\/mwe-setup.jpg\" alt=\"mwe-setup\" width=\"786\" height=\"398\" srcset=\"https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2015\/01\/mwe-setup.jpg 786w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2015\/01\/mwe-setup-300x152.jpg 300w, https:\/\/www.cqdx.ru\/ham\/wp-content\/uploads\/2015\/01\/mwe-setup-768x389.jpg 768w\" sizes=\"auto, (max-width: 786px) 100vw, 786px\" \/><\/a><\/p>\n<p>Power is supplied by a standard USB socket (5 Volts), just hook it up to your shack computer or any USB charger.
