Hi John, Mike, Several folks have done various measurements including myself. Measurements and records between big box VNA and the nanoVNA would be of interest. However, that said, my best guess is

Hi. Got my from Lusya/Aliexpress on the last week. Its in black color with battery and USB-C connector. Was ordered in begin of June. Just one note - included 50 Ohm dummy load looks like was
