OK, viewed the videos and now have the firmware updated to Hyugun's last, Feb 2020. Things working as expected, however:
1. My NanoH4 saves the scan start and stop frequencies OK, so when I turn the unit off and on again they are still there. But it doesn't save the Trace selections. I have to delete unwanted traces and format the desired ones anew each time. Is that normal?
2. The NAnoSaver program to view data on a PC screen detects the NanoVNA when connected and powered on, but no other Nanosaver command seems to have an effect. For example, I can't set traces or scan start/stop frequencies from the Nanosaver PC program. Is there some simple thing I am missing?
3. For the Nano Scale command, is there any command that labels the scale values on the display? IN other words, puts 1.0, 1.25, 1.5 etc up the Y axis and the frequencies along the X-axis? I know I c am move the marker around to see the frequency, but am wondering if there is a way to label the X and Y axes with values.
