GOOZEEZOO ATS-20+ Portable Shortwave FM AM SSB Radio

The GOOZEEZOO ATS-20+ is a compact, Si4732-based portable full-band radio receiver that delivers FM/AM/LW/SW reception with SSB support, clear speaker output, and DSP-enhanced sensitivity for reliable listening on the go.

Designed for hobbyists, travelers, and anyone who wants dependable shortwave and broadcast reception in a pocket-sized package, the ATS-20+ combines a metal housing, a front-firing speaker, and selectable audio filters so you can tailor sound and selectivity to different bands and conditions. It supports stereo earphones, includes an FM antenna, and retains a replaceable SI4735-compatible PCB for users who may want to upgrade or service the radio later.

What bands and modulation modes does the ATS-20+ support?

The ATS-20+ covers the full broadcast and shortwave set of bands so you can receive international shortwave, AM/MW, FM, LW, and single-sideband transmissions used by amateur and utility stations. It also decodes LSB and USB for SSB reception, letting you listen to ham operators and other SSB sources.

• FM, AM (MW), LW, SW coverage across multiple HF and VHF ranges
• SSB support including LSB and USB for ham and utility signals
• 22 pre-configured channels across commercial and amateur frequencies
• Compatible with external antennas for improved band-specific reception

How does audio quality and filtering improve listening?

The front-mounted speaker delivers clear, full sound from a compact chassis while DSP-driven filtering sharpens selectivity and reduces interference. Multiple bandwidth filter options let you prioritize clarity or fidelity depending on whether you’re tuning weak shortwave stations or strong local broadcasts.

• Front speaker tuned for strong mid-range and vocal clarity
• Selectable filters: 0.5, 1, 1.2, 2.2, 3, and 4 kHz for tailored audio and selectivity
• 3.5 mm stereo jack for private listening with headphones (not included)
• DSP enhances signal-to-noise and reduces adjacent-channel interference

How portable and rugged is the ATS-20+ for travel and field use?

The radio is built in an aluminum-alloy chassis that balances lightweight portability with durability. At roughly 3.6 × 3.2 × 1.5 inches, it slips into a bag or large pocket, and the included FM antenna plus external antenna support make it flexible for indoor or outdoor setups.

• Compact footprint fits into backpacks and travel kits
• Aluminum alloy shell resists wear and adds structural strength
• Included FM antenna; supports specific antennas for other bands
• Replaceable PCB with SI4735 footprint for potential upgrades or repairs

What technical features help catch weak or noisy signals?

The Si4732 chipset used in this model is known for its sensitivity and selectivity, while DSP processing further strengthens weak signals and reduces noise. Together they help the receiver pull in distant stations with less hiss and fewer spurious tones.

• High-sensitivity Si4732 chip for distant-signal reception
• Digital Signal Processing improves clarity and anti-interference
• Multiple bandwidths let you balance noise rejection vs. audio fidelity
• Stable tuning across all bands for consistent listening

Who is this for: The GOOZEEZOO ATS-20+ is ideal for shortwave listeners, radio hobbyists, and travelers who want a small but fully featured receiver capable of SSB and full-band listening. It suits users who value portability without sacrificing control over filters and reception, and those who appreciate a service-friendly design with a replaceable PCB.
