I am not really sure which version nanoVNASaver software I am running....

To verify it actually functions - I hooked to my old 440MHz ground plane.
I am NOT looking for ANY accuracy , just
"proof of concept".
When I sweep from 400 to 500 MHz I get pretty much expected SWR display
pretty much scattered BELLOW 2... good enough for government work
When I "narrow it down" to
440 to 450 MHz
it is WELL bellow 1.2 - not expected when compared to previous measure
When I change back to
400 to 500 MHz
there is absolutely no change in ANYTHING on the software displays
and I get "I/O error " and I have to rerun the software.
What gives ?
and if the answer is
upgrade to the latest version
DO NOT BOTHER TO SAY SO
How did you calibrate?
(was it a 101 point cal covering 400-500 or something like that? or a "multisweep" cal with more points?)
