The cover on vs. off naturally changes overall circuit capacitance as well
as temperature. What you do is see how much you are off with cover on, and
adjust with cover off, in a direction to bring the circuit right on with the
cover on. In other words, you overcompensate the setting for the final
cover on case. A few iterations should give you a hint on how much change
is needed to be right on. marking the slot position with cover off, vs.
cover on, when the frequency is right on should give you the range. Then
set the slot halfway and see if that is not the optimum. It may be less
than the slot width, so a deft touch is needed.
