Maintainers: wrxchaotasp2sfx

We thank them for having previously participated in the radio shack maintenance: czechu, dfgg

Thanks to many non-HS OMs for supporting, including: Leon SP5DL, Rysiek SQ9MDD, Rafał SQ5FWR, Mirek SP5GNI, Krzysztof SP5OXF

Due to human safety, legal compliance, and the risk of equipment damage, always ask the maintainers for permission before touching any devices, especially the antenna system, power supplies, and transmitters.

• CG Antenna CG-3000 Remote Automatic Antenna Tuner

• Remember: An antenna tuning unit (ATU) does not retune the antenna to a different band; it only protects the transmitter from damage. It does not magically grant resonance or efficiency to an inherently inefficient antenna structure.
• Exceeding operational limits (power, frequency ranges) can permanently damage the antenna system, measuring equipment, or dummy loads.
• Always operate in QRP mode (low power) during tests and experiments to minimize risks.
