It allows you to use your 2 Meter or 440 MHz handheld to practice Morse Code on-the-air. This unit comes in a small lightweight package that makes it easy to carry just about anywhere.\u003c\/p\u003e\n\u003cp align=\"justify\" style=\"line-height: 100%; margin-bottom: 0in;\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp align=\"justify\" style=\"line-height: 100%; margin-bottom: 0in;\"\u003eThe \"JIM HANDY\" produces great sounding sidetone that can be heard through the built in speaker while transmitting or not. The audio is a pure sinewave output that eliminates harsh keyclicks. The MFJ-552 provides the most challenging way to practice and learn CW; on-the-air. Now you can practice to upgrade your license or help a friend.\u003c\/p\u003e\n\u003cp align=\"justify\" style=\"line-height: 100%; margin-bottom: 0in;\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp align=\"justify\" style=\"line-height: 100%; margin-bottom: 0in;\"\u003eIt is important to remember that although you are sending Morse Code, you are NOT transmitting in the CW mode. To demonstrate common courtesy to other users, stay within 433 to 435 MHz and 442 to 450 MHz when transmitting on the 440 band. Stay within 144.6 to 148 MHz when transmitting on 2 meters.\u003c\/p\u003e\n\u003cp align=\"justify\" style=\"line-height: 100%; margin-bottom: 0in;\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp align=\"justify\" style=\"line-height: 100%; margin-bottom: 0in;\"\u003eTo practice good etiquette, always make certain that the channel is clear and quiet. Announce that CW practice is about to take place. Other users may like to listen, join in or create friendly competition. Although the \"JIM HANDY\" is a great tool for learning CW, it can be enjoyed by even the most expert CW users.\u003c\/p\u003e\n\u003cp align=\"justify\" style=\"line-height: 100%; margin-bottom: 0in;\"\u003e \u003c\/p\u003e\n\u003ch3\u003eProduct Manuals\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0289\/7782\/3843\/files\/MFJ-552.pdf?v=1787876701\"\u003e\u003cb\u003eDownload Product Manual\u003c\/b\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"MFJ Enterprises Inc","offers":[{"title":"Default Title","offer_id":67898720256099,"sku":null,"price":119.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0289\/7782\/3843\/files\/MFJ552R.jpg?v=1794256385","url":"https:\/\/mfjenterprises.com\/products\/mfj-552-jim-handy-cw-interface","provider":"MFJ Enterprises Inc","version":"1.0","type":"link"}
