vna/J 3.1.20 available

Version 3.1.20 of vna/J is released.

  • The application JAR can be downloaded from here as usual.
  • Analyze moved from Tools menu to File menu to have it always available
  • Some VNAs have longer startup time and will produce peaks at the begin of the scan. To reduce this issue, the generator can be kept on after scan. Thanks to Cristian/YO3BN for the hint
