..and looking to orient myself. Have a NanoVNA H as well as a NanoVNA H4 but this query is about the "H" only. I flashed the firmware with a DiSlord clone (v1.1.01 (Build Dec 30 2021) after having done the same with the DiSlord v1.0.38 version.

After getting everything set the way I want it, I power down the "H" unit and power it back up and it reverts to the original psychedelic flashing phantasmagora that frankly looks like the unit is going ape-****. How does one retain the preferred config versus the firmware original default?

Second question: I upgraded the firmware from a v0.4.0-something version and am wondering is there a similar version to the v0.5.0 version? If so, where might that dfu reside.

Thanks.

It may be that a calibration is not stored in memory 0, so when the unit starts, it starts uncalibrated, and that could cause a display with a lot of unusual activity.
Could also be that the device is using the wrong clock chip mode. There are 2 versions, and if you have an earlier hardware platform (sounds as if you do), then you should be running the Si MODE. (look on the back of the nVNA. if it has _MS in the model, you have an MS device; else you have an Si device) Go to EXPERT SETTINGS, and confirm that the button says Si----. If it says MS----, tap it and change it. Then do a cal over some range...I usually do 50k-900M, and store that in location zero. that way when the device start, it will use a calibration.

William,
I will answer your second question:
You can find a lot of information about the upgrade in the forum wiki and you can also visit my website where I try to gather current information.
