And I think the question is really more about “radiated emissions” or “radiated susceptibility.
So let’s say you’ve got your 100 mW 2.45 GHz Tx hanging off NanoVNA which in turn is hanging off the 40m dipole that’s connected to the NanoVNA. How much power actually couples into the VNA? I’m pretty sure isn’t 100 mW.
And most of those “remote serial port” aren’t radiating 100 mW.

But the input of the NANOVNAs is wide open. Enough RF at any frequency
into that port, and compression and false readings will occur.

Complete nonsense, I have a BT module tapped to my Nano H clone and there
are no issues. BT works at 2.4G, way out of the range of Nano.

This very subject came to the surface about a year ago. I don't
remember
any resolution to the question of remoting any of the NANOVNAs via an
RF
or
BT link. Problem is even a radiating BT source at +10 dBm would likely
overload the VNA and more local BT energy could potentially damage the
front ends. The close proximity of a BT (or other RF technology) to
remote
the NANOVNAs is not a good idea.

I have the "H" model. I searched for AE6TY and SimSmith and found a
groupsio page, nothing immediately specific to the subject.
Looking at the BT to serial converters online it looks like they are
7pin
serial and most likely contain a serial uart.
Ill have to dig into the interfaces much further.
