I guess there are a few on the list with access to Agilent or other high-end VNAs. It would be nice to see a side-by-side comparison made between the H4 and the high-end, and a pdf or YouTube video

Open it and check if there is a battery installed - there may not be. I doubt the piece of film has anything to do with a battery as the 450ma battery is connected via a header.

Just bought a NanoVNA. Powers up fine from the USB port on switch on and charging led flashes and ON led illuminates. After charging unit wont power up with USB lead disconnected as if battery not

Maybe better thinking of making the vna more robust with a bigger screen and a jog switch that doesent self destruct,needs better connectors and a metal case imho.

G'day all, J-B Weld is my friend... with all the mini/micro/pico USB/HDMI/younameit sockets under my jurisdiction, I stick the bloody things down with tiny amounts of "the Glue from God", no

I am still trying to decide which one of these devices to get to review on my YouTube channel (hamrad88). There are so many to choose from with prices from $35 to $99. I found this one on Amazon this

From: Birdman Can anyone tell me if the font is any bigger on the 4" over the 2.8"? I know the screen is bigger, but is the font bigger, or is it the same? And yes, I know there is another firmware

As you have many switches anyway you may consider a switchable high pass filter to get rid of the fundamental and thus being able to use the 3rd harmonic. Not sure if your mixer can handle up to 9GHz

Still no price on shipping one to the uk yet then?

Gabriel, These linearity problems are solved T-Check and other linearity tests show good results, I was able to correctly measure S11 and S21 of a 1.8GHz low pass filter and 2GHz band pass filter On

I just looked at that phone you linked,couple of points,firstly they dont ship to the uk and secondly its on android 6 so no good for the nanovna app!!,hat a shame,does anyone know the part

The ICOM IC-7300 has a 4 inch touchscreen display had has been a big success so I think lots of hams and experimenters will find it sufficient. Have you looked at the Android app? Mike N2MS

Please, what is the difference between nanoVNA-F and nanoVNA-H4 ? Stepan

Bird uses a 5.5" Samsung cellphone for the display and compute base of their SK4000 antenna analyzer series so it is possible.?I mentioned the SK4000 way back last September. When you think about it,

the two nanoVNA-H and H4 compared. -- *73, Lucio I0LYL Rome, Italy*
