Thanks Joe. Your work is close to being the gold standard of KZitem applied RF videos.

Thanks for the time and effort making this video. Laidukas is my nickname, in Lithuanian language it means "wire". My true name is Aivaras. Again, thanks for the video.

I bought a 3.1 the other week and it should be here any day! I'm very excited. Thank you for the video.

It's great for working above 300MHz, but for narrow band, low frequency work, the original NanoVNA will out perform it. They are cheap, so it's no big deal to get both.

@@joesmith-je3tq 900mhz is the frequency I need specifically, for LoRa networking, but I also want to do some 2.4ghz long range stuff down the road. Figured this was the best device in my budget, although the original NanoVNA was very tempting given the price.

@@steve_seguin The original NanoVNA has poor performance above 300MHz where it uses harmonics. I was surprised when the software was changed to support >900MHz. The LiteVNA is a much better choice. There is also the open sourced LibreVNA. I understand it is a full 2-port VNA but I have never looked into it.

Looks like one of the RF traces between the cans has been buried - might be helping with radiated noise immunity.

Interesting, I just got my 3.1 version and it didn’t have a soft plug. I think the 3.1 also stopped the parasitic drain on the battery so customers dont get them with a dead battery past the BMS safety low point. Mine did arise with a battery at 3.95 volts.

It may have been made by a different company.

@@joesmith-je3tq It’s possible . I did look this up later and also found that the 3.1 also changed the LCD touch screen being used according to the *official website because to supply chain issues. Now the big question is what is the LiteVNA67 (I keep running across that firmware). The name indicates it might be. 7 inch screen version but I can’t seem to get a definitive answer. Have a great day.

Could be a typo. For myself, they could remove the screen, touch, card reader, thumb switch, battery and 90% or more of the firmware. I would rather them have changed the architecture to allow for narrow band measurements, lower noise, higher directivity ....
