On my H4, I recently started having a problem calibrating. During cal the smith chart is sweeping wildly displaying a lot of straight angled lines about the cursor. In the end the cal fails as evidence by measuring the cal standards.
This started after flashing firmware to H4 dislord 1.2.40 though I suppose it could be coincidental.
I opened it and checked for cracked solder joints but didnt see any. Then I flashed it a few more times, testing in between, and finally after 2-3 attempts it started behaving normally again.
Has anyone else seen this before? Maybe I had some setting botched?
