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
