FT-840
AMATEUR HF TRANSCEIVER

The FT840 as a first-time rig, back-up, or main station transceiver, has the features and dependability that both beginners and seasoned operators will appreciate.

Direct Digital Frequency synthesis
Two DDS and a magnetic rotary encoder provide silent, smooth tuning and very fast transmit/receive switching. Frequency accuracy and stability are assured by driving both DDSs from a single master oscillator, and the optional TCXO-4 temperature-compensated crystal oscillator is available for enchanced stability.

Clean transmitter output
The digitally synthesized local signals ensure clean, low-noise transmitter output: up to 100 watts on all HF amateur radio bands in CW, SSB and FM* modes, and up to 25 watts carrier in AM mode.
*) FM operation requires optional unit

Wide receiver dynamic range
The receiver tunes all frequencies between 100 KHz and 30 MHz in 10-Hz steps. For clear weak-signal work, the low-noise, high-performance receiver front-end feeds an active FET balanced mixer.

Quality construction
The FT840 uses a modular die-cast RF power amplifier/heat sink with an internal thermally switched fan to allow full transmitter output power without any rear panel protrusions to block access to connectors and controls.
