[GCARC] NanoVNA H4 Upgrades

[Christopher Prioli AD2CS]

For a limited time only, I am offering SD Micro card reader upgrades to
owners of NanoVNA H4 devices.  This upgrade is one that allows screen shots
and data traces to be stored to a disk file completely within the NanoVNA,
without the need to be tethered to a computer running VNA Saver or a
similar application. The cost for this limited-time offer is a flat twenty
dollars, which includes the SD card slot, modification of the enclosure to
provide access to the card slot, and a 32GB SD Micro card.

There are some things to be aware of...

   - This update applies ONLY to the NanoVNA H4
   - The update can be performed ONLY on those NanoVNA H4 devices that have
   the card slot provision on the PCB.  A quick removal of the cover and a
   look at the PCB will tell you if the update can be applied to your device.
   I can look at it if you do not want to open up your device.
   - The rate is available ONLY when the NanoVNA H4 is in a plastic
   enclosure.
   - The update also requires a firmware update if your existing firmware
   does not support the SD card. The firmware update will be done if required
   as a part of the installation process.
   - The date and time will be set into the device at the time of
   installation, as these factors are used for the NanoVNA H4 file naming
   convention.

When completed, you will be able to save screen shots and trace data to
disk files on the SD card, which can then be read in a standard computer
for use of the data as you please.

If you are interested in having this upgrade performed on your NanoVNA H4,
let me know and we can make arrangements to perform the upgrade.  It is a
useful upgrade, and I have done several of these already.
