Aviation radio communication is essential for flight safety and reliable coordination between pilots and Air Traffic Controllers within the 118–137 MHz Very High Frequency (VHF) Airband. This study evaluates the feasibility of a low-cost, field-oriented platform for acquiring and visualizing VHF Airband activity in the Palembang region, rather than validating a formal interference-detection method. The platform integrates an RTL-SDR receiver, a VHF Airband antenna, and SDR Sharp software configured for amplitude-modulated reception, real-time spectrum display, and waterfall visualization. Signal conditions were examined using received signal strength, noise level, and signal-to-noise ratio (SNR), while unusual spectral behavior was assessed qualitatively from elevated noise floors, irregular peaks, and atypical waterfall patterns. Several active aviation communication channels were observed across the monitored band. The strongest observed signal quality occurred at 125.10 MHz, where the SNR reached 25.9 dB. At 132.55 MHz, an anomalous and potentially interfering spectral event was observed, characterized by an elevated noise floor and irregular activity; however, this does not constitute confirmed interference because no calibrated reference instrument, source localization, repeated validation, or independently defined detection threshold was employed. Because the monitoring duration, number of sessions, and per-frequency repetitions were not systematically documented, the measurements should be interpreted as observational snapshots rather than stable channel statistics. The results demonstrate the platform’s suitability for preliminary spectrum data acquisition and visualization. Future work should establish controlled, repeated, and calibrated measurements before extending the platform toward automated classification or decision-support applications.
