: Replaces original "stretched" fonts with a minimalistic, highly readable interface featuring a 7-segment frequency display.
What do you have (e.g., ATS20+, standard ATS20, or a specific variant)? Which operating system do you use on your computer?
: Replaces blocky, distorted default layouts with clean, highly readable, custom-designed frequency displays.
for SSB (Single Sideband), which is essential for clearly receiving ham radio operators. Visual Overhaul: ats20 firmware exclusive
, the ATS_EX firmware (latest v1.18) introduces several high-end features previously unavailable on stock units: Reworked Visual Interface
Set the baud rate to 115200 in the AVR Dudes program and select the Arduino bootloader using the STK500 V1 protocol.
If the screen glitches or buttons behave erratically after flashing, perform a factory reset via the menu or hold down the encoder knob while powering on to clear the EEPROM memory. : Replaces original "stretched" fonts with a minimalistic,
High latency when turning the rotary encoder.
At first glance, the ATS20 (and its popular ATS20+ variant) looks like just another pocket-sized SDR receiver. A compact OLED screen, a Si4732 DSP chip, a simple encoder knob. For the uninitiated, it’s a cute, low-cost radio scanner. But for those who delve into the world of custom firmware, the ATS20 transforms from a toy into a surgical instrument for RF exploration.
Reviewers from RadioReference note that while the firmware drastically improves the user experience, it cannot overcome hardware limitations like poor front-end filtering. : Replaces blocky, distorted default layouts with clean,
This allows the user to monitor frequencies in complete darkness and silence, with the only indication being a silent haptic (if modified) or a headphone trickle. Stock firmware has no concept of tactical silence.
Independent developers worldwide have spent countless hours optimizing the code for the ATmega328P's limited flash memory (32KB). The most notable firmware forks—such as those derived from the famous Ricardo Caratti (PU2CLR) library—introduce a suite of advanced features. 1. True Single Sideband (SSB) Support
The combination of affordable hardware and exclusive, feature-rich firmware makes the ATS-20 and ATS-20+ a standout product in the world of portable radio. It's more than just a receiver; it's a . Installing Goshante's firmware is the single best upgrade you can perform, effectively turning a cheap device into a powerful, feature-packed SDR.
: Holding down the designated keys renders a real-time signal strength bar, turning your budget display into a professional benchmark indicator. 2. Streamlined Control Layout
for AM modes to reduce fading distortion and the ability to adjust receive bandwidth via the encoder. Battery Management:
