Easier said then done :)

If you're using PC software - it's a file.

Definitely the problem.
* HAMs often change feeds on a whim and don't remember to recalibrate
Who me? Never do that. No way. :)

I have all kinds of calibration standards, that's not a problem, but "doing" calibration ahead of time (and being able to store it on nano) is often a challenge
