Measuring is the most important part of our hobby and it is often the most overlooked. I have build a fair number of simple test gear.

It as difficult as building a simple SSB transceiver. Very much worth the time.<\/li>\n<li><a href=\"https:\/\/www.vu2ese.com\/index.php\/2020\/06\/19\/two-tone-generator\/\">Two Tone Generator<\/a>\u00a0A two tone generator is an essential test gear made with just four transistors that helps you evaluate your amplifiers, mixers, receivers for distortion. Distortion makes all the difference between a pleasant receiver and a horrible sounding one, between a clean transmitter and bad, splattering one on air.<\/li>\n<\/ul>\n<p><strong>Design Tools<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/www.vu2ese.com\/index.php\/2020\/06\/18\/feedback-amplifier\/\">A Feedback Amplifier Calculator<\/a><\/li>\n<li><a href=\"https:\/\/www.vu2ese.com\/index.php\/2021\/05\/17\/cascade-calculator\/\">Calculator for Cascading RF stages<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>I am a radio amateur, Ashhar Farhan.
