Hi Ben,

I did not reply immediately to your post because I hoped that someone might have more information than I have. I have not personally used the software at the link below with either my ANAN-100 or my ANAN-200D but perhaps others have, or maybe Phil VK6APH will jump in with comments on the status of this version of the Hermes VNA software.

https://github.com/TAPR/OpenHPSDR-SVN/tree/master/Hermes/VNA/Release

The Hermes VNA User Guide can be downloaded here:

https://github.com/TAPR/OpenHPSDR-SVN/blob/master/Hermes/VNA/Documentation/Hermes%20VNA%20User%20Guide_V1.8.pdf

Make sure you read the "Operation" section of the guide and note the suggestion to place a 6dB (or higher) attenuator at the TX output when using the VNA software. Also note the suggestion to power cycle the hardware before using the VNA software and power cycle it again before returning to regular operation with OpenHPSDR (or Thetis).

It might be worth a look. What's the worst that could happen?

Ben,

I just installed the Hermes VNA software and it runs fine on my Windows 7 computer. It connected right up to my ANAN-200D on its little private subnet and patiently waited for me to figure out how to run a simple plot. I ran the calibration procedure (open circuit, short circuit, 50 ohm termination) and then ran it with my Hex Beam connected to the ANAN-200D. It delivered the plot below:

Looks good to me, but what do I know? :shock:
