AGC preset:
OFF - AGC is off.
LONG - preset with long AGC reaction (approximately 750 ms). Recommended for phone
modes.
SLOW - preset with slow AGC reaction (approximately 500 ms). Recommended for phone,
digital modes.
MED - preset with medium AGC reaction (approximately 250 ms). Recommended for CW,
digital modes.
FAST - preset with fast AGC reaction (approximately 100 ms). Recommended for CW, digital

DSP functions:
- enable the RX equalizer (enabled on the picture).
- enable the TX equalizer.
- binaural audio mode (the phasing of the audio signal within the RX filter gives a stereo-
like effect).
- enable the adaptive Noise Reduction to clean the signal from noise interferences.
- enable the First Noise Blanker for impulse interference.
- enable the Second Noise Blanker for impulse interference.
Note:
· The NB1 and NB2 algorithms are different. Try each of them to reach the best impulse
interference reduction. NB1 and NB2 Noise Blankers can be used simultaneously.
