What is a duplexer and how do you tune one? November 06, 2017 15:15 6 Comments

I've tuned a lot of duplexers over the years. Since we install duplexers in our repeaters and sell duplexers as part of our system packages, I often get asked about them. How do they work? What are they used for? And how are duplexers tuned? To answer these questions, W2AEW, just put out a great video where he answers these questions and more. If you're interested, I encourage you to watch this video.

All the best,
