Many stages do similar things, and knowledge of only a few main families is necessary to understand how a basic transceiver works. This video takes you through these basic building blocks, discussing oscillators, amplifiers, mixers and filters. I describe where they're used and show examples of completed modules. If you're memorising this for an exam, think FOAM (Filters, Oscillators, Amplifiers, Mixers). Afterwards watch Part 2, which arranges the blocks to form various types of receivers, transmitters and transceivers. https://www.youtube.com/watch?v=aGTQymZv8uM PS: If you liked this video please consider supporting Amateur Radio VK3YE by: Subscribing on YouTube, Checking my books page at https://books.vk3ye.com ​​​​​​​​​​​​​​​​, Shopping on Amazon via: https://amzn.to/3iiDQXv​​​​​​​​​​​​​​​ , or, Shopping on eBay via: https://ebay.us/i9DuWP (then if you buy something I'll get a small commission at no cost to you) Sat, 09 May 2026 06:14:13 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/c09bbfc2-471e-427d-a23c-265572b12996 All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
