Adjust the compressor mode using the dedicated switch or buttons on the unit.
6.3 grafiskais ekvalaizers
The 4-element graphic equalizer allows you to fine-tune your audio for optimal performance in FM and SSB modes, especially for DX (long-distance) communication. Adjust the sliders for the following frequencies:
- 270 Hz
- 540 Hz
- 1000 Hz
- 2000 Hz
Each element has a range of +12dB. Experiment with settings to achieve the desired audio quality for your voice and operating conditions.
6.4 Modulation Prevention Circuit
This circuit provides an audible alarm for 30 seconds if a prolonged transmission is detected. After the alarm, the unit will automatically return to receive mode to prevent accidental continuous transmission.
7. Apkope
