Full Title

Full titles differ between systems:

IPC:

Discontinuous tuning; Selecting predetermined frequencies; Selecting frequency bands with or without continuous tuning in one or more of the bands, e.g. push-button tuning, turret tuner > with variable tuning element having a number of predetermined settings and adjustable to a desired one of these settings > operated by hand

CPC:

Discontinuous tuning; Selecting predetermined frequencies; Selecting frequency bands with or without continuous tuning in one or more of the bands, e.g. push-button tuning, turret tuner (H03J7/00, H03J9/00 take precedence; for bandspreading H03J3/10) > with variable tuning element having a number of predetermined settings and adjustable to a desired one of these settings > operated by hand

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
