RF Oscilloscope sampler
It is an RF Oscilloscope sampler designed to connect in-between your transceiver and antenna to display the signal out of your rig.
This project was inspired from episode #110 of Ham Nation titled “Bob Shows How to Connect Your Scope to Your Transmitter”. In this episode Bob Heil K9EID will show a basic schematic for the design that I have made digital here.
In my design I had to use two .01 mfd capacitors in parallel since I did not have the correct .02 value, but other than that I was able to scrounge up all of the parts that I needed as they were lying about at my club station at W9YB. This is just one of the many projects that several folks put together spontaneously at W9YB, usually on a Friday afternoon when we are there just hanging out.
I was really lucky to find this small box that was perfect for the SO-239 UHF style connectors and it housed everything I needed perfectly. I plan on building more of these with some other members in the future and using them to display the characteristics of RF on an oscilloscope.
Here are some more photos:
This was a very easy but fun project to build. I really had a blast using this and analyzing the RF signal of some of the HF radios at W9YB.
Feel free to download the schematic and build one for yourself. And if you would like, let us know how your build went in the comments below.
