ITEM NO : Icom IC-7800
PRODUCT NAME : Icom IC-7800 HF/50Mh Transceiver
  • 110dB dynamic range and a +40dBm IP3 in the HF bands
  • Internal distortion reduction
  • Improved blocking by three roofing filters that block strong adjacent signals with selection widths from 15kHz, 6kHz and 3kHz
  • Icom's DIGI-SEL
  • Less internal phase noise
  • Multiple AGC loops
  • Full AGC controls
  • Digital IF filter allows operator to adjust filter shaping (sharp or soft), filter bandwidth, and center frequency characteristics, without missing the action
  • Digital twin PBT (Passband Tuning) that allows flexibility of both the IF shift and narrowing of the digital IF passband by moving the IF passband
  • Digital manual notch filter
  • Variable level noise reduction
  • Adjustable noise blanker reduces pulse type noise.
  • 50MHz band preamplifier and mixer
  • Quad processing
  • Two completely independent receiver circuits
  • Real time spectrum scope
