Slowly rotate the encoder knob clockwise or counterclockwise. You are now fine-tuning in increments of 10 Hz to 50 Hz. Rotate until the voice sounds natural and intelligible. Press the button again to lock it in. 4. Hardware Optimization: Making the ATS-20 Better
has a simple eight-button interface. Understanding the interplay between buttons and the encoder is key to a "better" user experience. Basic Controls Switch on the back to turn on/off. Tuning ( TUNE/BFO/ATS knob): Rotate to change frequency. Volume ( Vol+ / Vol- ): Press to adjust audio.
For weak SSB or Morse Code (CW) signals, narrow the filter () to eliminate background static. 📡 Advanced Reception Tips (Getting Better Signals)

Use the 'Mode' button to switch between FM, AM, USB, and LSB. Remember: Most Ham operators below 10MHz use LSB , and those above 10MHz use USB . 4. Improving the Audio: The Speaker Mod
AM, LSB (Lower Sideband), USB (Upper Sideband), and WFM (Wide FM for broadcast radio)
The stock manual says "Connect antenna." That is it. This is a crime.
. They are often sold without consistent branding and may require firmware updates or hardware adjustments for optimal performance. Essential Controls and Operation ATS20 & ATS20+ How to Reset
Rotate to move across the band. A fast rotation usually increases the step size, while a slow rotation allows for precise fine-tuning.
Clip a long piece of insulated copper wire (20 to 50 feet) to the telescopic antenna or use the onboard BNC/SMA antenna jack. String it outside or near a window to pull in weak international stations.
Toggles tuning increments (e.g., 1, 5, or 10 kHz in AM; as low as 10 Hz in SSB for upgraded firmware).
Most users don't realize the tuning knob is also a button. Short-pressing the knob usually cycles through tuning steps (1kHz, 5kHz, 10kHz, etc.). This is vital for navigating from a broad scan to fine-tuning a specific SSB (Single Sideband) signal.
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
