    - Inductance and reactance values correspond well with those predicted by online calculators such as toroids.info. - However, predictions for Q have mixed results when compared to the Micrometals Q-Curve Catalog found HERE. - I suggest using their catalog for accurate Q prediction. It has been previously identified that Q values predicted using Micrometal's curve-fit equations do not reconcile with measured Q as discussed here. -
