I am not really sure what kind of problem you are running into....( did not bother to read) But if it looks like a software issue, smells like a software issue and quacks like a software issue, but

5v power should *always* be available on a USB port, so slow charging can happen even on a dead device. What is negotiated are faster charge rates, so, as you noted, a dead device will need to slow

Up front - few years back I got involved with nanoVNASaver and soon realized this is not a right group to ask about nanoVNASaver software. BUT - if there is a remote possibility that has changed Does

I was going to quit this thread, but... I left the nanoVNA running overnight , connected to my PC and I did "shutdown" and turned the PC power source off. Turned off the D_link power source too. In

The OS still controls (or at least manages) the hub's power as part of the whole USB tree, even if the hub itself receives external power. That is, the hub can decide if it wants to turn power on to a

Interesting question. I mostly use my Nano VNA on HF bands. It has never failed in any aspect - one port antenna, 2 port filter tests, over all of the HF bands anyway. But when I did the 440 band

My PC is "open architecture " ASUS motherboard in old desktop case. nanoVNA USB port is via powered D_Link " USB hub. It has not been powered for about 6 months ,,,, I am going to let it fully

I charge my NanoVNA from my PC's usb port every time I use it, work fine. Are you using a laptop, or a tablet maybe? N0NC

Or it's not responding to the request for more current.

This make no sense you pause the sweep, or after a single-sweep, the LED is steady on. hence there is no flash ? DO I understand this correctly ? Calibrated and maybe even not calibrated (?) nanoVNA

...to be continued there is more when the "charge LED" is off and I plug the USP cable to wallwart - it starts flashing... hence it is charging after coupe of minutes when I unplug the wallwart - the

I had it calibrated for different band ....No I did not change "sweep points " but I may have lost the connection - my battery does not seems to last very long - but that may be different issue.

The green LED next to the wheel switch (actually the one on my nanovna-H4 is blue): the firmware 'flashes' this LED when the device is sweeping. If you pause the sweep, or after a single-sweep, the

How did you calibrate? (was it a 101 point cal covering 400-500 or something like that? or a "multisweep" cal w

Ok I won’t bother fox out

I am not really sure which version nanoVNASaver software I am running.... ( did not bother to look ) To verify it actually functions - I hooked to my old 440MHz ground plane. I am NOT looking for ANY

Please keep the discussion impersonal and civil. That is hilarious reply to my original post.... I got ONE LED function solved - not thanks to this group... Now you can redeem yourself - if so desired
