    Roger from R&L gave me one of these, let's start a club learning session! I'll compile what we learn and share it out in a video for all to grow together.

    Thank you for your video.

    As with the NANO VNA I have found the Tiny SA to be easier to run on a PC.

    I have read too many comments about the screen on the NanoVNA and the Tiny SA being too small.
    75" monitors are now very cheap from Walmart if a 50" screen is too small to see.....

    I think that it will not be so popular like the NanoVNA due to its limitations when things come to real analyzation, I've checked it more than a year ago.

    I have a Rigol DSA815TG spectrum analyzer and still find many uses for my TinySA.
    One use is for tracking down RF noise generated by junk electronic items around the house. Try walking around with a full size spectrum analyzer that has to run on AC trying to find RF issues. Hi Hi
    Another use I found was for testing mobile antennas. I set up a remote pickup antenna far from the car and ran coax back to the car. Connected the TinySA to the coax, sat in the front seat of the car and now I have a calibrated field strength meter in hand. I had a fun day in the park testing and comparing numerous mobile antennas.
    Don't sell the little TinySA short, it's a handy tool to have around.

    I have had the TinySA for some months now and want to learn about more uses for it and how to hook it up if possible to a large screen. Will watch the video.
    Thank you so much! Great idea.

    One use for a small SA like this is to tell if the clock crystal on a PCBA is starting up OK. Make a small coil (several turns) with some enamel wire, center it over the crystal, power the device up, and see if you get a peak at 20MHz or whatever frequency the crystal uses. Not something you need to check every day, but nice to have the tool when you do.

    W8LJZ, how to hook it up if possible to a large screen.

    Either for the TinySA or the NanoVNA it is just a matter of downloading the software to your computer and plugging in the USB cable from the TinySA or NANO to your computer. You then just need to turn on the device and connect to it using the connect option in the software. You can then choose which options from the pop up that you want to display on your monitor.

    This is the link for the TinySA software.

    Now this is interesting ! Been looking at the NanoVNA but have no clue how to use it . As long as it is not too involved this could decide me to take the plunge and buy one.
