Over a year ago I found some information on a very small VNA for around $60. Since this NanoVNA was less than 1/10 the price of any other VNA with a built in display, I jumped at it. It gave me an instrument that had the frequency response I would need to work on a SA.
There was an IO group formed to support the little VNA.
Following that group I found another group about Home Brew Test Equipment. One of the ongoing projects in that group was a Tiny SA. Several different versions of that were being developed and it looked very promising. Around the first of the year a TinySA group was started for several people who were testing a future commercial version of the TinySA. Some of the info on this group looked very interesting, especially a short video on the nearly finished product.
Just the other day I saw a post on the TinySA group, that the product was available for order. The TinySa is being produced by the same person who originally produced the NanoVNA. With that as a recommendation I quickly placed my order, since I understand there is only an initial production run of 300 being made.
The availability of a less than $100 SA with a range of 100kHz to 350MHz (240- 950 MHz. without bandpass filter )will make the life of the home-builder a lot more fun if not easier.
Now all I have to do is wait #@*& !
