The stock telescopic antenna is fine for local FM, but for Shortwave (SW) or Ham Radio (SSB), it’s often inadequate.
Used in SSB (Single Sideband) to "fine-tune" the voice so it doesn't sound like a cartoon character. Band: Short press cycles through FM -> AM -> USB -> LSB. 2. Improving Reception: The Secret Sauce
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. ats20 radio manual better
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.
The ATS20 relies on a (the knob) and a series of buttons. Most buttons have a "short press" and a "long press" function. The Knob: Used for tuning frequency and navigating menus. BFO/VFO: This is the most important toggle. VFO mode: Changes the actual frequency. The stock telescopic antenna is fine for local
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)
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) By mastering the BFO and Step increments, you
To get the most out of this device, you need a "better" manual—one that explains the hidden quirks of its firmware and how to actually pull signals out of the air. 1. Understanding the Interface (The Basics)
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 .
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.
