Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Want Advice On Starting Fresh

Marc WR2I 2023/02/24 14:57

After a hardware failure and a repair attempt, all does not seem well with my SAA-2N. No help from seller or manufacturer. I would like to start over and need firmware recommendations and what needs to be cleared from any memory in the unit.

When I reset all, setting are still recalled from saved. When I flash FW, the same happens. I have been running DiSlord on the SAA-2N. The FW I have, 20210328-V2-grid-fw_with_FPU V2 480x320 grid, starts with a totally wacked out touch cal and the screen flipped.

I am not sure what FW to use and what is best on this device at this point in time. I would ultimately like to start from scratch and rebuild my saved files. Any input would be appreciated.

Marc it looks like your VNA is doing well. Just go in to menus and flip
ower LCD using buttons, do an LCD calibaration any you are ready to go...
