Spot on. Great video. This is the easiest way to explain tuning a duplexer. I especially like the way you double check the insertion loss at the end. I would recommend this video for anyone who may have struggled with duplexer tuning.
Great video explaining the basics! I've volunteered to help administrate a local 440 amateur repeater, so I'm sure I'll be able to put this to good use!
Aunque no entiendo muy bien el inglés pareció entender el procedimiento anteriormente ya es manejado un 2001 y es una excelente herramienta para el ajuste de filtros pasa banda duplexer, etcétera Gracias por el video
Hi, I have one of this duplexer ...., Q is it possible to tune it on a completely different freq ? I. e. tx 431 an rx 433 MHz ? ... or they need mechanical adjust ? thanks
This looks like the duplexer that is often listed as a 20w model. I do not understand the requirements internally of a duplexer, but I am very curious if they can get smaller? Not just in wattage, but in the physical size. If I want a duplexer used for portable hilltop repeaters when hunting or working on the ranch I don't need anything too serious. Currently the repeater is a solar powered setup and due to not having a duplexer I am simply doing cross-band to stay full duplex. Since I am only using HT's for the TX & RX radios, I don't need a full 20W duplexer, physical size is much more important to me, can these things be built smaller? Better yet, how far apart should the two frequencies be (within the same band) to not require a duplexer?
Thanks , Hay we live near a cell tower and have a "smart meter" on our utility box, I often hear a hum sometimes, is there anyway to measure such frequencies and or determine where it is coming from? Peace

Thinking of buying this spectrum analyzer, your video explained a lot. Thanks for the time to create and upload.
Like your going to spend $1,494.00, yea right doc
THANK YOU! This is just what I have been looking for. And you are even using the same service monitor that I have available!
Hytera Means technical excellence & simple solutions, Excellent video presentation.
Outstanding video sir!
Great video! Now I understand how it works.

So do you have to turn any of those screws on the duplexer or is it all software?

do you remember what model duplexer you are tuning?
Is it normal that you join the port "Gen out" and "ANT" with your coxial cable, the line is located a - 61 dBm? Should not it be closer to 0 dBm?
How does it look so easy when everyone else does this? I can’t get mine right no matter what I do. Using a nano vna
Hi am trying to learn how to tune my 2 meter duplexers. what spectrum analyzer do you recommend for a beginner
also nice video
Can this be done using a Marconi instruments 2955b?
WHEN YOU TUNE THE HIGH SIDE YOUR TUNING ALL SIX SCREWS???
