Oscillator Board parts diagram: 1 bare PCB, 2 fixed oscillator, 3 variable oscillator, 4 volume oscillator, 5 mixer-detector, 6 oscillator coil, 7 SMD passive (R/C/L), 8 connector. 13 parts in 8 top-level items. — Oscillator Board parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Bare PCB	1×	Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2	Fixed Oscillator	1×	Reference LC oscillator
3	Variable Oscillator	1×	Antenna-pulled oscillator
4	Volume Oscillator	1×	Volume-side oscillator
5	Mixer-Detector	1×	Heterodyne mixer
6	Oscillator Coil	5×	Ferrite-slug tuned inductors
7	SMD Passive (R/C/L)	1×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
8	Connector	2×	Antenna and panel headers
