Jim & Jim,
I should have clarified that I was speaking of the Rig Expert line.
I'm wondering whether the ability to store multiple cal's on other
units would overcome the ease of use of the AA devices - great UI,
decent in sunlight, etc.
I'm only wondering mind you :-)
Or, inspire people to make VNAs with sunlight readable displays.
Or, inspire people to make software for sunlight readable smartphones
(most of them) that can use the VNA as a peripheral.
It *is* interesting, since the utility of devices like the venerable
MFJ-258/MFJ-259 is starting to be a bit less obvious. (for instance,
when my MFJ died, I decided not to try fixing it... )
One could make a Arduino with daylight readable LCD that would connect
to a NanoVNA and display the same info a MFJ does (assuming you can
figure out how to make an Arduino a USB host. Or you could connect
directly to the serial port on the NanoVNA.
Blowing up a NanoVNA (not a NanoVNA2)) is a bit more difficult than
blowing up a MFJ - there's resistive loss ahead of anything sensitive on
the NanoVNA, so a strong signal would saturate but not destroy the backend.
