有极弱信号需要测向@438.495MHz
The signal was very weak but severely impacted communication quality at 438.5 MHz due to significant interference within the bandwidth.
Currently, the antenna cannot support directional finding; it's constantly getting bogged down in noise, and after going downstairs, I can't receive anything at all. Finding the convergence point is also useless.
Urgent need for CJU dual-frame antenna diagrams.
