Hi? Rune and QRP RX Yes indeed, running a calibration on my NanoVNA-H itself first, solved my prtoblem. The calibration with 60 segments and 10/5 Averaging over 10K to 900M is still running :-D:-D Oh

Using cho45's NanoVNA apk avoids Internet dependency: https://play.google.com/store/apps/details?id=net.lowreal.nanovnawebapp .. and Amazon Fire tablet is currently < US$30

Thanks Rune and QRP for responding that quickly, I did nothing more? than the flashing and trying to calibrate in NanoVNA-Saver, I wil run a calibration on NanoVNA itself and see if it solved it !

Another way to do this would be to package it up with an Android tablet and use NanoVNA WebApp as the user interface (remove or hide the built-in LCD). I'd like to try this but the android app won't

even if you cleaned your connector with alcohol, you're needs to perform calibration after that

any change, firmware or hardware requires a new calibration.

Hi Jos, I haven't done anything in particular relating to the NanoVNA-Q firmware, so any changes, assuming you are using the same version of NanoVNA-Saver, is in the firmware. :-) The individual

if firmware detects incompatible calibration it reset calibration and settings. You're needs to perform calibration after firmware update.

Hi Rune After Flashing NanoVNA-Q-0.4.4 I found that the calibration in Nan0VNA-Saver has changed. I am used to set the sweep settings in the NanoVNA-Saver to a high number of segments and averaging

it can enter into DFU with no issue, this is your compiler issue.

Is that gecko image on the cover linked to them in some way as I had problems with a basic NanoVNA with that logo. Yes I know a logo isn't going to matter but maybe the 'dumb cloners' try to badge

Exactly.

The nanovna-saver source code is there so on the Mint 17.3 host could you not do an altinstall of python 3.7 without tramping all over the 2.7 install and then use a python environment and switch

Connections with LCD incompatible, firmware has insufficient free space See wiki /files for a possible retrofit -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files:

is it possible to retrofit a 4.3 inch screen to a nanovna that has a 2.3 inch one,has anyone tried this?.
