[SARK-100 Pc Scan] SWR Analyzer Software

Now a days small VNA’s are available at a reasonable cost. Older instruments like the SARK-100 and its other brother and sisters lack of the possibilities of a VNA. However, with this new software I hope many SARK-100 users can still get useful data from these devices.

It is the first update since 2018, when I got my first VNA, and did not really have any use for the “old antenna analyzer”. But I have realized that many people, (probably radio hams) still visit my site and look for the software to read data. This was the trigger to make a software that will blow the heck out of this now old instrument.

All calculations are made within the software, no external Excel sheet is used. And it is now really fast, this makes it a really fine instrument to use.

Owen (VK1OD) has written a blog about this program. http://owenduffy.net/blog/?p=10536 That was many years ago and has really nothing to do with this program.

The SARK-100 is a SWR analyzer and the range is from 160M to 6M. The Mini-60 and MR-100 also works with this software.

One nice feature is the PC interface which makes it possible to do some automation.

I have made a program that communicate with the SARK-100 and plot the data both as a graph and in a smith chart. The data can also be stored as an CSV file.

Remember that you also need the USB driver and the .NET Framework installed. There is no installation file in this version just unzip the file and then start the program with the exe file.
