I was rather surprised by the quality of the analog television signal sent using an narrow-band FM carrier.<\/p>\n<p> I was required to construct a cable in order to transmit using the FT-60R. I used the CT-44 adapter which converts the three-sleeve 3.5mm TRS connector to a separate audio and mic output (a 3.5 and 2.5mm TRS plug). With an additional three-sleeve plug, it&#8217;s feasible to construct a cable to interface with the sound card minus the CT-44 adapter. Here&#8217;s a snippet of the Yaesu TNC schematic from the FT-60R manual. <\/p>\n<p><a href=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/Picture-1.png\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/Picture-1-300x235.png\" alt=\"\" title=\"FT-60R TNC Diagram\" width=\"300\" height=\"235\" class=\"alignnone size-medium wp-image-723\" srcset=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/Picture-1-300x235.png 300w, http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/Picture-1.png 479w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>The white plug is for the output from the sound card and the black cable is a simple stereo cable.<\/p>\n<p><a href=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/IMAG0010.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/IMAG0010-300x200.jpg\" alt=\"\" title=\"FT-60R TNC Soundcard Cable\" width=\"300\" height=\"200\" class=\"alignnone size-medium wp-image-724\" srcset=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/IMAG0010-300x200.jpg 300w, http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/IMAG0010-1024x682.jpg 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>And for the picture itself&#8230; <\/p>\n<p><a href=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/K2NXF.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/K2NXF-300x240.jpg\" alt=\"\" title=\"K2NXF\" width=\"300\" height=\"240\" class=\"alignnone size-medium wp-image-726\" srcset=\"http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/K2NXF-300x240.jpg 300w, http:\/\/abrammorphew.com\/notes\/wp-content\/uploads\/2010\/12\/K2NXF.jpg 320w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The other day I was able to send transmit and receive an SSTV transmission across the room using two Yaesu HTs and a trial copy of MultiMode from Black Cat Systems.
