Asa ca te invit sa deblochezi 75% din potentialul transceiverului, lucrand in moduri digitale.<br \/>\nSigur, unele transceivere au deja interfata digitala built-in, dar multe nu au. VHF-ul meu sigur nu.<br \/>\nTot ce am de facut este sa aduc sunetul din difuzorul statiei la intrarea LINE-IN a computerului si LINE-OUT (sau Speaker) din computer la intrarea de microfon la statiei. Cand vreau sa transmit, softul produce semnalul modulator si statia il emite. Ce receptionez, este decodat de acelasi soft si afisat pe ecran. Este vorba de text sau de imagini. Ma refer la APRS\/PACKET, PSK, MFSK, RTTY, SSTV (frumooos) si altele.<br \/>\nSigur, cineva trebuie sa apese PTT-ul. Aici am cateva variante:<br \/>\n1. <strong>Manual mode<\/strong> &#8211; apas eu cu degetul cand dau SEND pe ecran (ca la tara)<br \/>\n2. <strong>Semi-auto<\/strong> &#8211; iau un pin RTS de la portul serial si fac o adaptare la PTT-ul statiei. Softul comanda portul serial dar mai trebuie tras un fir de la statie la calculator (pe langa cele 2 de sunet). Poate laptopul meu nu are serial. Adaptor&#8230;<br \/>\n3. <strong>Full-auto<\/strong> &#8211; fac un circuit VOX si cand apare modulatia, pac! se apasa singur PTT-ul. Te incurajez sa alegi asta.<\/p>\n<p>Cateva dizertatii tehnice apoi trec la scheme.<br \/>\n&#8211; CALITATE! Cablurile folosite trebuie sa fie de calitate, ecranate si ecranul pus la masa.<br \/>\n&#8211; Intre statie si computer trebuie izolare galvanica.<br \/>\n&#8211; Experiment. Eu nu am putut implementa nicio schema exact asa cum am gasit-o. In primul rand majoritatea pieselor sunt marca Dumpster Diving, asa ca am pus si eu ce am avut. Apoi unele scheme pur si simplu nu merg. Solutia: imaginatie, experiment, studiu. Asta e ordinea mea, fiindca nu poti sa te &#8230; in gustul omului.<\/p>\n<p><strong>Constructie<\/strong>:<br \/>\n1. Am luat o cutie pe care am replicat butoanele de pe microfonul-PTT. Cablul de casca este bobinat pe o ferita, pentru deparazitare. Pinout-ul este pentru Yaesu, ca asta am.<br \/>\n<a href=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/20150122_134011.jpg\" target=\"_blank\" rel=\"attachment wp-att-167 noopener noreferrer\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"167\" data-permalink=\"https:\/\/racov.ro\/index.php\/2015\/12\/22\/interfata-digitala\/20150122_134011\/\" data-orig-file=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/20150122_134011.jpg?fit=800%2C450&amp;ssl=1\" data-orig-size=\"800,450\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;2.6&quot;,&quot;credit&quot;:&quot;Picasa&quot;,&quot;camera&quot;:&quot;GT-I9195&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1421934010&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;3.7&quot;,&quot;iso&quot;:&quot;500&quot;,&quot;shutter_speed&quot;:&quot;0.0588235294118&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"20150122_134011\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/20150122_134011.jpg?fit=800%2C450&amp;ssl=1\" class=\"alignnone wp-image-167 size-thumbnail\" src=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/20150122_134011-150x150.jpg?resize=150%2C150\" alt=\"20150122_134011\" width=\"150\" height=\"150\" srcset=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/20150122_134011.jpg?resize=150%2C150&amp;ssl=1 150w, https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/20150122_134011.jpg?zoom=2&amp;resize=150%2C150&amp;ssl=1 300w, https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/20150122_134011.jpg?zoom=3&amp;resize=150%2C150&amp;ssl=1 450w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/a><a href=\"http:\/\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout.jpg\" rel=\"attachment wp-att-159\">\u00a0\u00a0 <\/a><a href=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout.jpg\" target=\"_blank\" rel=\"attachment wp-att-159 noopener noreferrer\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"159\" data-permalink=\"https:\/\/racov.ro\/index.php\/2015\/12\/22\/interfata-digitala\/pinout\/\" data-orig-file=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout.jpg?fit=1856%2C1763&amp;ssl=1\" data-orig-size=\"1856,1763\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"pinout\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout.jpg?fit=800%2C760&amp;ssl=1\" class=\"alignnone wp-image-159 size-thumbnail\" src=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout-150x150.jpg?resize=150%2C150\" alt=\"pinout\" width=\"150\" height=\"150\" srcset=\"https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout.jpg?resize=150%2C150&amp;ssl=1 150w, https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout.jpg?zoom=2&amp;resize=150%2C150&amp;ssl=1 300w, https:\/\/i0.wp.com\/racov.ro\/wp-content\/uploads\/2015\/12\/pinout.jpg?zoom=3&amp;resize=150%2C150&amp;ssl=1 450w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/a><br \/>\n2.
