What are the alternative to vnasaver? I got it running fine but discovered
that it is painfully slow and it doesn't mark frequency line in small
increments.
What I want is something that is fast as the standalone vna so I can do some
what ifs regarding antenna tuning for various frequencies and save the results
as well. Maybe VNA_QT does that?
VNA-QT is not a program for your NanoVNA. NanoVNA-QT (VNA View) is the native software for the NanoVNA V2 Plus4 and VNA6000 series.
There are some very old apps for the NanoVNA like NanoVNA Sharp and NanoVNA Mod3 but they were very basic. NanoVNA App is the one I use and it has very nice features. DiSlord and Owen Duffy have made some nice improvements since the original author OneOfEleven stopped working on the project.
NanoVNA Saver scans reasonably fast if you set the frequency range to your band of interest and then calibrate. Here is a video I made for you showing me matching an antenna for the 20M band using a manual tuner. You can see the SWR, Return Loss and Smith Chart change as I rotate the knobs.
