This was such a fun project. This was my first direct conversion build, and I learned a lot along the way. The biggest challenge was finding stable capacitors for the oscillator. In my first attempt, I used whatever I had in my junk box, but those capacitors drifted all over the place. Mica caps seemed expensive and difficult to get in Bangalore. I ended up buying surface-mount NP0 capacitors instead. Soldering them was a hassle, but they are much cheaper and easier to get here. <\/span><span style=\"white-space-collapse: break-spaces;\">Next step will be more mods and experimentation! The first improvement will be in the BPF. I will replace the regular ceramic caps with NP0 caps and re-tune it.<\/span><\/i><\/span><\/b><\/div>\n<div><b><span style=\"font-family: inherit;\"><i><span style=\"background-color: white;\"><br \/><\/span><\/i><\/span><\/b><\/div>\n<div><b><span style=\"font-family: inherit;\"><span style=\"background-color: white;\">Here is Ashish&#8217;s receiver inhaling CW: <i> <\/i><\/span><\/span><\/b><\/div>\n<div><b><span style=\"font-family: inherit;\"><i><span style=\"background-color: white;\"><br \/><\/span><\/i><\/span><\/b><\/div>\n<div><b><span style=\"font-family: inherit;\"><i><\/p>\n<div class=\"separator\" style=\"clear: both; text-align: center;\"><object class=\"BLOG_video_class\" contentid=\"c8c1a2ca7c648180\" height=\"266\" id=\"BLOG_video-c8c1a2ca7c648180\" width=\"320\"><\/object><\/div>\n<p><\/i><\/span><\/b><\/div>\n<div>\n<div class=\"separator\" style=\"clear: both;\"><b>Congratulations Ashish &#8212; Welcome to the Hall of Fame! <\/b><\/div>\n<\/div>\n<div><span style=\"background-color: white;\"><br \/><\/span><\/div>\n<div><span style=\"background-color: white;\"><\/p>\n<div class=\"separator\" style=\"clear: both; text-align: center;\"><a href=\"https:\/\/blogger.googleusercontent.com\/img\/a\/AVvXsEi3LrHDc7641xykZDknYgdA6WD5XD6AKYjxUuvW592nmHc0tEvTZYMlV9_6qTvoyQUDg61c54kBL8Za_6ecwENnsm5Qbynx5HOqRIyTrBNgD9DI44S6Ygsn9Kvs2vsuFn4y4OcVMZpTzJdsUaxACUFmG5zSO1DOv3sulxcJLQPfe-eVEQStvxtYlr2oZDU\" style=\"margin-left: 1em; margin-right: 1em;\"><img loading=\"lazy\" decoding=\"async\" alt=\"\" data-original-height=\"768\" data-original-width=\"1024\" height=\"300\" src=\"https:\/\/www.homebrewradio.us\/blog\/wp-content\/uploads\/2025\/06\/image_1753114464.png\" width=\"400\" \/><\/a><\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\">Ashish N6ASD<\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\"><\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\">\n<div class=\"separator\" style=\"clear: both; text-align: center;\"><a href=\"https:\/\/blogger.googleusercontent.com\/img\/a\/AVvXsEj15hD1QRGhqGkNtQP9S4rctGoJLa5p-3Y7NmW1aaUA3_KuO3QX8THuy0BHuQT7p4G5TAisL11edUT1BDSLgfKWF2v5ssbucMe-6NSN11oit0QZGWNMxwt4Dt66P6Cyb7laUztaBtWShIqaqijtxZcYDxQRriMBDu7P0-eMgiaUSmAf7hpvuUkA5HGDBYQ\" style=\"margin-left: 1em; margin-right: 1em;\"><img loading=\"lazy\" decoding=\"async\" alt=\"\" data-original-height=\"641\" data-original-width=\"500\" height=\"400\" src=\"https:\/\/www.homebrewradio.us\/blog\/wp-content\/uploads\/2025\/06\/image_1753114460.png\" width=\"312\" \/><\/a><\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\">The resemblance between Ashih&#8217;s photo and the famous<\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\">1818 painting by Caspar David Friedrich is completely coincidental, <\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\">but quite remarkable. <\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\"><a href=\"https:\/\/en.wikipedia.org\/wiki\/Wanderer_above_the_Sea_of_Fog\">https:\/\/en.wikipedia.org\/wiki\/Wanderer_above_the_Sea_of_Fog<\/a><\/div>\n<div class=\"separator\" style=\"clear: both; text-align: center;\"><\/div>\n<\/div>\n<div class=\"separator\" style=\"clear: both; text-align: left;\"><\/div>\n<p><\/span><\/div>\n<div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Ashish N6ASD is a really good guy.
