Blending the high performance digital frequency synthesis techniques from the Yaesu FT-890 with the operating convenience and affordability of the FT-747GX, the FT-840 adds a choice of two optional remote automatic antenna tuners and a wealth of convenient functions. For compact base and mobile stations, the FT-840 set the new standard for high-performance affordable transceivers. As a first-time rig, back-up or main station transceiver, the FT-840 has the features and dependability that both beginners and seasoned operators will appreciate.
Low Noise Receiver
The receiver section of the FT-840 includes direct feed to the first mixer, for excellent rejection of intermodulation. The careful design yields a highly sensitive receiver that is renowned for its "quiet" performance.
Ease of Operation
Without the clutter and complexity of some other rigs, the FT-840's outstanding ergonomics mean you always find the button or control you need quickly. The reduced number of keys also means that there is a greater proportion of the front panel space dedicated to the display than on competing rigs.
To help reduce interference on SSB or CW, the IF Shift feature allows you to move the center frequency of the passband around, rolling off interference from either the high or low side. Once a feature only found on top of the line transceivers, it's here for you on the FT-840!
Direct Digital Synthesis (DDS)
The lightning-fast DDS system provides instant lock time for the synthesizer, along with ultra-fine tuning steps, for silky-smooth tuning similar to that found on older analog VFOs.
Computer Control Capability
The FT-840 supports Yaesu's CAT System for computer control. Use your favorite logging program to read your current operating frequency, or send frequency commands based on "spots" from your local packet cluster.

Hard to beat this rig. It is short on features but it does everything it was designed to do very well. I loved mine!
I've had mine since Dec 2011. I use it daily. Simple but affective. Solidly built for both mobile and base station use. The receive audio is excellent. Good reports on my transmit audio using a MC-50 microphone. I have an external DSP (Timewave DSP-9+) for use during contests. Very good rig for about $400.00 used.
I have owned my 840 since its last year of production and it has never needed a repair as of March of 2017! I primarily use it for cw and have the 500 hz filter installed and the filter for AM phone.The only feature I wish it had was vox but being a cw op primarily no big deal. I don't miss a keyer as I only use bugs and straight keys. I consider the receiver section to be quite good and I also use it for swling.A nice dependable little rig. I constantly get positive comments on the xmit audio on both am and ssb with the MD 100 mike.
