Do not leave it plugged into a computer or a "noisy" cheap wall charger while listening. The "switching noise" from the charger will bleed into the radio's circuitry, creating a loud hum on AM and SW bands. Always listen on battery power for the cleanest signal. Why a "Better" Manual Matters
If you want to listen to Ham Radio operators, you must switch to or LSB (Lower Sideband) . Find the frequency (e.g., 7.175 MHz for 40m ham band). Switch mode to LSB. Press the BFO button.
Use a simple clip-on wire antenna. Clip it to the telescopic whip and run it outside or near a window to significantly reduce "noise floor" interference. 3. Mastering the Bandwidth (BW) ats20 radio manual better
The is a powerhouse of a portable radio, beloved by the enthusiast community for packing All-Band (FM, AM, SW, LW) and SSB capabilities into a pocket-sized metal box. However, if you’ve just unboxed one, you likely noticed that the included "manual" is more of a cryptic pamphlet than a guide.
If you are zeroing in on a specific station, drop it to . This prevents you from overshooting the signal. 6. Battery Management The ATS20 uses a built-in lithium battery charged via USB. Do not leave it plugged into a computer
The stock telescopic antenna is fine for local FM, but for Shortwave (SW) or Ham Radio (SSB), it’s often inadequate.
Narrow the bandwidth (e.g., to 3.0kHz or 2.5kHz) if there is a lot of static or an adjacent station bleeding over. For FM: Keep it wide for high-fidelity audio. 4. Navigating the SSB (Single Sideband) Why a "Better" Manual Matters If you want
A common mistake beginners make is leaving the bandwidth wide open.
The ATS20 is based on the , which is incredibly sophisticated. Most users only ever use 20% of its potential because the default instructions are poor. By mastering the BFO and Step increments, you transform a "toy" into a legitimate piece of radio gear.
Slowly turn the dial. You will hear the pitch of the voice change. Adjust until the speech is clear and natural. 5. Advanced Tweaks: Step Sizes The "better" way to tune is to adjust your .
