Please remember folks - This info is all in the NanoVNA WIKI - link is at the bottom of every email post...
Please refer to the Wiki and Files areas as they have a pile of very good reference material, posted by a number of forum members over the last 6 months.
Cheers,Larry

My desk-top PC (laptop) has never had an external device connected to it. Therefore no peripheral drivers have been installed. Might not be a problem in general but it was with this old HP Win7 Pro.
When I attempted to connect the NanoVNA-H to the PC nothing happened!? Tried a few things, posted some "need help" messages but nada.
Gyula Molnar, HA3HZ, came to my rescue.? He provided me with the information and resources to find what was needed.
One source was STMicroelectroncs where I found and installed a version that did the job. (VCP_V1.5.0_Setup_W7_x64_64bits.exe). SUCCESS!!
Nanovna-saver found the serial driver at COM4 and ran a scan using the installed calibration (?) : Useless info as nothing was connected, but it seemed to be working OK.? I've since connected a 4:1 Voltage BalUn, the input to an adjusted ATU ( 50ohms?) and some filters of various configurations. The BalUn looked really good scanned from 3.5 to 54 MHz.? I'll check it again after doing the calibration. Not sure what the tuner results meant: Needs further research...8^)
Many thanks to Gyula for the help; I'd have had no idea where to look for the needed driver**.? ST also has versions for W8 which were also downloaded with the Zip file.? Maybe someone else would have a use for the info.? There are 2 versions each in the Zip file, W7 and W8, of 32 and 64 bits.
** I tried Microsoft but not much help, maybe because Win7 is not longer supported.
