The stock signal meter is notoriously inaccurate. The new firmware update implements a calibrated Received Signal Strength Indicator (RSSI) and Signal-to-Noise Ratio (SNR) readout in real-time. This allows you to precisely align external antennas and calculate propagation metrics. Dynamic Bandwidth Filtering ats20 firmware exclusive
Upgrading the ATS-20 to this firmware is a core requirement to use it. Because the ATS-20 contains an onboard Arduino (ATmega328P) programmer, the process is simple. Here is a summary based on standard methods used by the community. | Feature | Stock / PU2CLR Firmware |
Offers precise SSB steps (10/25/50/100/500Hz) and broad AM steps up to 1MHz. Dynamic Bandwidth Filtering Upgrading the ATS-20 to this
Simplifies Single Sideband (SSB) operation by allowing fine-tuning (e.g., 100 Hz steps) directly from the main VFO control without exiting to separate menus. Advanced Metering:
