New 32-Bit Floating Point DSP
New 24- bit AD/DA Converter
•Ultra-wide dynamic range
of signal management
•Clear signals without
distortion
•Many DSP functions
CL:JD:PM:RN 10/25/01 Page 7
AGC Loop Management
•Multiple AGC loops
- Rejects unwanted signals or noise
•Better than rigs with a single AGC circuit
-Copies weak signals without pumping AGC
from stronger signals
-Eliminates need to constantly “ride the
volume”
•Reduces user fatigue
•Provides for nearly “hands free” listening!
•Selectable AGC time constants
- Flexibility
- Speed
- Perfect for working pileups
CL:JD:PM:RN 10/25/01 Page 8
Set Mode (AGC)
If the AGC is too fast or too slow
Quick setting change can make it just right
Different settings for different modes
CL:JD:PM:RN 10/25/01 Page 9
Eliminates adjustments when hopping around the band.
