NanoVNA and TinySA

These amazing pieces of test gear bring some otherwise very expensive test equipment within the reach of radio amateurs. Years ago, these would have been out of my price range. I now have both.

NanoVNA

Well, I think I know how to drive it, so I may try to better match my earth-electrode "antenna" in the ground tomorrow after I get back from Cambridge in the afternoon.

For the price it is some instrument.

NanoVNA

Recently, I purchased one of these, mainly to measure the VSWR of my various antennas. At the moment, I am still learning to drive it. 

There are a few YouTube videos that help too. You seem to get a lot for your money.  I am also charging the battery. At the moment, I am still learning.

On my "to do" list is measuring the VSWR of all the antennas I use. 

NanoVNA - very tempted

The NanoVNA is a palm sized vector network analyser  I have the TinySA, which is its brother spectrum analyser. Like many things out of China, there are many clones, so you have to be sure you are buying originals and not copies. One of the things it can do is plot SWR against frequency, so you can check if your antenna is spot on.  It can also be used to check trap frequencies.
