I downloaded and installed the *45 software for my H4 and the readings are
all over the place over 300MHz now, so will be interesting to see how this
thread progresses. The added features are promising if the readings were
stable.

So I just downloaded and installed the latest software for the NanoVNA-H,
version 1.0.45. I upgraded from 0.4.5-4 which was released on January 18th.
I have a dummy load that I tested it on, and the original measurements
from the old firmware was:
2m: ~1.1
70cm: 1.4-1.5 and relatively flat
After installing and clearconfig, I calibrated and tested the dummy load
again just now and got the following:
2m: Still ~1.1
70cm: 1.7 to 1.9+ (it climbed over the 440 to 450 Mhz range.)
I used the same coax for all tests, so I'm not sure why the SWR jumped 0.3
points+ (or changed at all) just because of a software update.
Right now I spend my time in 2, and 70cm, so I need to be confident of the
70cm number.
Thanks. 73, Bruce KE8QFP
