Re: Firmware with arbitrary scan length
Erik, Would you please post the source code or a link. Dave Kirkby asked me about the loss of dynamic range when harmonics are being used. This prompted me to read the datasheet for the audio codec.

Re: Early app for the NanoVNA
With the help of Ohan, there's now a 32bit standalone .exe available as part of release 0.0.6 on Github. If you were having problems before, do give that a go, and feel free to report any problems

Re: New FreeRTOS-based nanoVNA 4.3" 800x480 LCD on Aliexpress
SPACE OPQA, Oh I see, you meant the RF Demo board. Deepspace is the OEM for the demo board shown in nanoVNA-F photos. You can order the board directly from them with components and connectors already

Hi Rune -- It's not really clear what dll "Access is denied" applies to. The file expat.py referred to just above that error does NOT exist and in of your zip files or anywhere else on that machine.

Re: Early app for the NanoVNA
Hi Harry, since the build does work on a number of machines, including on this Win7 64 bit machine I'm typing this on, which doesn't have that directory, I don't think that path in particular is the

Re: Early app for the NanoVNA
Hi Rune -- No, I wasn't trying this on Ubuntu -- his machine is Windows 7, 64bit. That path can't possibly exist on just about any other user's Windows machine. So I don't know how it could work

Re: New FreeRTOS-based nanoVNA 4.3" 800x480 LCD on Aliexpress
If anyone in the group could design this board, one could populate it at home, since the board could be printed in China, it would cost under 10USD including shipping I reckon... TTH components would

As for the price, $139.00 would be a bargain for the nanoVNA-F if the nanoVNA wasn't already on the market at it's sub $50 cost point. I suspect the developer is trying to maximize his profit before

I notice that there is no mention of touch screen capabilities on their web site. I wonder if touch capability was lost when they went to the new display. Hope not. If anyone ends up with one please
