From your "Site Designer":
This is Gil, your "webmaster." I hesitate to pin that moniker upon myself in that I'm no expert on HTTP or any of the other newer web programming languages. Using a WYSIWYG (look that up if you don't know what it is) site designer currently from Google and with a little spare time, you can build an incredible website yourself for free.
Be that as it may, I have actually had bequeathed upon from from this past Christmas, a really nice antenna analyzer. I've seen them work before and have salivated over a few, but, since I'm a poor ol' ham radio guy that works on a shoestring budget, have never had been able to find the extra money to purchase one at the price point that many of them seem to be going for. But along came Christmas, 2019 and Santa had placed one carefully under the tree.
Because of some of my ham radio buddies, I was somewhat familiar with the operation of the MFJ 269C but what I got really blew me away. I ended up with a Mini-1300 from eBay...a fully built vector network analyzer that is based on the ST Microelectronics STM32F746G Discovery Development Board and uses open source software from EU1KY. Ten years ago, a device like this would cost thousands but today, you can even get a mini VNA for under $50 and the Mini-1300 (at the time of this writing) for under $200. No instruction manual and barely any instructions online. Almost nothing in print and even with the YouTube videos, they don't tell you a lot of how it all works. I'm still working with it, but getting closer to figuring many of the functions. I'm currently working on an English manual and have will post what I have as of April 14, 2020. Below is the March 31, 2020 version, but there's not enough changed to post a new version. I will still have to do some translating of the "Chenglish" that is on this version, since some of it makes little sense. I'll keep working on this and updating as I discover more about this analyzer.
