ICOM IC-775DSP - Production: 1994 till 2002
The Icom IC-775DSP lets you pull out weak signals no one else can. Serious DX'ers require serious equipment. While the 775DSP may be fun to operate, it was engineered from the ground up using high-quality components and offering features and performance you will find nowhere else. Enjoy 200 watts from MOS-FET finals with full duty cycle operation. Keypad entry, preamp, IF notch, and analog meter, are featured. The rear panel has a heat sink and fan and AC cord input. Features: • All-Mode • Analog S/RF Meter • 180-10 Meters • Audio Peak Filter • VOX Function • IF Notch • 1 Hz tuning • Automatic Antenna tuner • Auto Antenna Selection • Memory Keyer • Preamp • CW Keyer • LPF/HPF • IF Monitor • Digital AF Automatic Notch • Digital Narrow CW • Digital Noise Reduction • Three Scanning Types
KENWOOD TS-950SDX - Production: 1992 till 2000
Swift performance and surgical precision are second nature to the TS-950SDX. Quality engineering blends aesthetic simplicity of form with a wide range of advanced features -- such as the built-in DSP (digital signal processor) and MOS FET final section. The result is exceptional transmission signal purity and first-class audio quality -- a benchmark for HF communications. And operating ease is just as impressive, thanks to the convenient menu system and many other user-friendly refinements. Features at a glance: 160 m ~ 10 m amateur band operation 100 kHz ~ 30 MHz general coverage receiver Built-in DSP (Digital Signal Processing) Digital AF filters MOS-type FET final section Dual-frequency receive SSB IF slope tuning Menu system Automatic antenna tuner AIP system 100 memory channels Built-in AC power supply TS-950SDX in detail: Digital signal processor (DSP) The digital accuracy and reliability offered by the built-in DSP, for both TX and RX, translate into an unprecedented advantage in HF communications.
Outstanding performance Carrier suppression is more than 50 dB, and unwanted-sideband suppression is also greater than 50 dB. Digital AF filters 15 LPFs for SSB and CW modes (with cutoff frequencies ranging from 600 Hz to 6 kHz), and 3 BPFs for FSK use (with a central frequency of 2200 Hz) are menu-selectable. Digital filtering eliminates key clicks.
