Ricetrasmettitore portatile FT-818 HF/VHF/UHF all mode. Incorpora tutte le molte caratteristiche di base ed attraenti del popolare FT-817nd, fornendo al contempo gli aggiornamenti richiesti al suo predecessore.

l'FT818 fornisce 6 watt di potenza di uscita con una fonte di alimentazione esterna.
Il pacco batterie NI-MH fornito in dotazione (32 mh) è stato aggiornato per fornire una capacità di batteria Maggiore (9,6 volt a 1900 MAH). Il nuovo FT-818 include anche un oscillatore integrato TXCO-9  che fornisce una stabilità di frequenza superiore al suo "antenato" ( 0,5 PPM) e la banda 5 Megahertz (WRC 15).

L'FT-818 include tutte le funzioni utili che sono incluse nelle FT-817nd come ad esempio:

  • Doppio VFO,
  • funzionamento in frequenza split,
  • cambio IF,
  • clarifier,
  • Noise blankerIF,
  • guadagno RF e controllo squelch,
  • IPO,
  • ricezione am aircraft
  • ricezione AM FM broadcast,
  • VOX,
  • tastierino elettronico integrato,
  • passo CW regolabile,
  • shift ripetitore automatico (ARS),
  • encoder-decoder ctcss incorporato,
  • 208 canali di memoria con 10 gruppi di memoria,
  • due connettori per antenna,
  • funzioni auto power-off (APO) e Time Out timer (TOT) molte altre funzioni
