foreign ebay deals, but didn't want to pay for overseas shipping
That is not how it started, and never was a goal. But few deals might slipped thru eventually. MM just couldn't resist when I packed both of my K2002's, stash of KX LTZ REF's and showed up at the airport
. That's how it started, and now we help each other to dispose whatever cash available on more rusty broken equipment.
I'd prefer to have mic off, when not relevant
. In general picture, we do rotations for our volt and ohm standards on periodic term (with intervals longer than desired, after all this is just hobby). For what we do, there is near zero value of any single time calibration, no matter how good it is. Because you anchor internal lab calibrations to that standard, but are completely at the mercy of unknown drift rate. So need to have at least three calibrations in same conditions with good uncertainty to establish good confidence in transfers. This is our main goal since 2015 or so, using best standards we can get hands on to minimize chances of errors. And thousands of kilometers between us cost pretty penny too.
