Larry, you forgot to mention that there is needs power off and power on just after clearconfig command.
If you use any kind of save command with no power off, it will leads to restore old bad config.
clearconfig command clears flash memory with configuration, but not RAM. The old config remains in the RAM and if you make save it will be stored back into flash. When you power off NanoVNA after clearconfig, and then power on. The firmware will see at boot time that there is no config in the flash and default config will be loaded.
