Although simple in design perceived performance is as good as a commercial transceiver.<\/p>\n<p style=\"text-align: justify;\">Main changes from Ashhar&#8217;s original design are the inclusion of a frequency counter and a Huff and Puff frequency stabilizer; this circuit will help keep the VFO tuned to the same frequency for long periods without any &#8220;drift&#8221;.<\/p>\n<p style=\"text-align: justify;\">As seen in the photo to the left, all components are mounted on to a single high quality PCB making construction relatively straight forward. The only &#8220;wiring&#8221; needed is short pieces of wire to connect the potentiometers to the PCB.<\/p>\n<p style=\"text-align: justify;\">To assist with construction there is a comprehensive manual that can be downloaded from this page, also available for download are a drilling template and front panel overlay.<\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: small;\">MKARS80 <span style=\"color: #339966;\"><a href=\"http:\/\/uk.groups.yahoo.com\/group\/mkars80\/\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #339966;\">support group<\/span><\/a><\/span><\/span><\/p>\n<p><span style=\"color: #339966;\"><a href=\"http:\/\/www.radio-kits.co.uk\/mkars80page.html\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #339966;\">Link<\/span><\/a><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Features Full 80M LSB coverage (3.5 &#8211; 3.8MHz) ~ 5 Watts output power Single conversion superhet with 4 pole crystal filter Frequency display with &#8220;Huff and Puff&#8221; circuit for stabilisation Modulation monitor &#8211; helps stop over modulation Volt meter &#8211; useful for battery operation Reverse polarity protection (fuse protected) The MAKRS80 is a QRP transceiver&hellip;<\/p>\n","protected":false},"author":2,"featured_media":27876,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_links_to":"","_links_to_target":""},"categories":[10],"tags":[259,359],"class_list":["post-27875","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-qro-qrp","tag-kit","tag-qrp","category-10","description-off"],"_links":{"self":[{"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/posts\/27875","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/comments?post=27875"}],"version-history":[{"count":0,"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/posts\/27875\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/media\/27876"}],"wp:attachment":[{"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/media?parent=27875"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/categories?post=27875"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cqdx.ru\/ham\/wp-json\/wp\/v2\/tags?post=27875"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
