The playing frequency is generated by the 8038 loop antenna?
For Tune not need a capacitor?

Hi ma330,
Here is the only Orbital average power loop antenna schematic I know of.
Explanation:
1. Solder all parts together as shown on schematic.
2. Turn on power switch.
3. Push Battery Test button to see if battery is strong.
4. Adjust frequency at 10K Frequency adjust potentiometer -- 20 Hz to 20 KHz.
5. Adjust power output at 10K power control.
6. See VLF and ULF frequencies broadcast into the air and ground from Orbital average power loop antenna.
Best Wishes,
