While you won\u2019t expect to work DX with this rig, it\u2019s fine for area communication. The map above shows the Retro-75\u2018s QSOs to date from my QTH in Newport, NH. Interestingly, distance didn\u2019t correlate to length-of-QSO. The two most distant contacts- Skowhegan, Maine and Huntington, Long Island- were 30-minute ragchews with good copy both ways. My antenna is an 88-foot center-fed with balanced line, at a height of 45-50 feet.<\/p>\n<p style=\"text-align: left;\" align=\"center\">Assembly instructions may be found at <span style=\"color: #008000;\"><a href=\"http:\/\/smallwonderlabs.com\/Retro-75_Instr.pdf\"><span style=\"color: #008000;\">http:\/\/smallwonderlabs.com\/Retro-75_Instr.pdf<\/span><\/a><\/span> and at <span style=\"color: #008000;\"><a href=\"http:\/\/smallwonderlabs.com\/Retro-40_Instr.pdf\"><span style=\"color: #008000;\">http:\/\/smallwonderlabs.com\/Retro-40_Instr.pdf<\/span><\/a><\/span><br \/>\nThere\u2019s a user group:\u00a0 <span style=\"color: #008000;\"><a href=\"http:\/\/groups.yahoo.com\/group\/SWLRetro75\"><span style=\"color: #008000;\">http:\/\/groups.yahoo.com\/group\/SWLRetro75<\/span><\/a><\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"text-decoration: underline;\">Board Kit<\/span> price <strong>includes shipping,<\/strong> see <a href=\"http:\/\/smallwonderlabs.com\/swl_ord.htm\"><span style=\"color: #008000;\">\u201cPricing\/Ordering\u201d<\/span><\/a><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #008000;\"><a href=\"http:\/\/smallwonderlabs.com\/Retro_Encl_Instr.pdf\"><span style=\"color: #008000;\">Click here for Enclosure kit instructions<\/span><\/a><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The \u2018Retro-75\u2019 75\/80 Meter AM Transceiver board kit &amp; The \u2018Retro-40\u2019 40 Meter AM Transceiver board kit This project is a frankly nostalgic look back at our hobby of 50 years ago.
