This is listed for parts are not working, I do not have a power cord for it and so I have never tried to turn it on. I don’t know if either one of these items work. If I do come across the power cord I will test it and will then update the listing. All the dials do turn and the buttons do press and spring back out. Some of the buttons do press in and hold and then need to be pressed again to spring back out and other spring back out immediately. Please use pictures to help determine condition. The buttons on the microphone also press in and spring back out. I will put the cover back on and replace the screws as best I can.

The Yaesu FT-840 is a fantastic choice for anyone looking for a high-quality ham radio transceiver that is both versatile and dependable.

Yaesu FT-840 HF Transceiver in Nice shape with the manual on CD, hand microphone, and the DC power cord. This is an really nice stock radio. Face of radio and top trim of radio are Excellent, top cabinet has a few scratches, a good looking and performing radio, built solid. MOD 1: Has all band transmit enabled. The 2 watt 8.2 ohm regulator resistor that typically burns up has been upgraded to an 8.2 ohm beefy 7 watt resistor that will handle the heat and last a long time. I get Excellent reports and receive is very sensitive. Radio is right on frequency all around. VERY good audio reports with this hand microphone. The FT-840 uses a modular die-cast RF power amplifier/heat sink with an internal thermally switched fan to allow full transmitter output without any rear panel protrusions to block access to connectors and controls. Modular circuit design employs surface-mount components on composite epoxy boards for high efficiency, reliability and serviceability. The FT-840 weighs under 5 kg, and runs cool all the time. 16 Bit Main CPU. The 16-bit main microprocessor is assisted by four co-processors to provide the simplest possible control interface for the operator. Two independent (A/B) VFOs for each band (20 total) hold their own frequencies and modes, as well as clarifier offsets and repeater shifts, when used. One hundred memories store all of this data for both VFOs, giving a total of 220 independent sets of frequency, mode and other selections. Of course all memories can be freely tuned and scanned, but ten special memories also let you limit the tuning/scanning range between their stored frequencies. External PC control of most functions by a serial-port-equipped external personal computer is made possible using the FIF-232C CAT Interface option connected to the CAT jack on the rear panel. 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. A 12-dB attenuator can be inserted in the receiver front end for clear copy of even very strong signals. FM operation requires optional unit. DIRECT DIGITAL FREQUENCY SYNTHESIS. Two direct digital synthesizers (DDS) and a magnetic rotary encoder provide silent, silky-smooth tuning, pure local signals and very fast transmit/receive switching. Frequency accuracy and stability are assured by driving both DDSs from a single master oscillator. IF SHIFT, REVERSE CW SIDEBAND & EXTRAS. Interference rejection is facilitated by the unique up-down-up’ conversion scheme, and also provides an adjustable IF shift control to vary the receiver pass-band. Special features for CW include the reverse CW sideband feature, which prevents having to re-tune lost signals when switching between LSB and CW modes, and helps side-step adjacent interference. The adjustable CW pitch (400-Hz 1000-Hz) lets you match that used by your TNC or multi-mode controller.

Yaesu FT-840 HF Transceiver in Good shape with the manual on CD, hand microphone (non Yaesu), and the DC power cord (no handle). Has a few marks here and there but looks good and works very well. This is an really nice stock radio. MOD 1: Has all band transmit enabled. The 2 watt 8.2 ohm regulator resistor that typically burns up has been upgraded to an 8.2 ohm beefy 7 watt resistor that will handle the heat and last a long time. The external speaker jack sometimes can cut out the internal speaker which is Very common in this radio but typically by putting in a mini plug in to the jack and taking it out it will bring back the internal speaker. I did this a while ago and it’s been fine since. I get Excellent reports and receive is very sensitive. Radio is right on frequency all around. VERY good audio reports with this hand microphone.

C : Very Good -A few scratches but looks good. A few scratches that are not visible unless you look closely. Please check the photos for detailed conditions. This is a radio that I bought a long time ago. It had been in the storeroom for many years. It has been stored without being used much and has not been used for many years, so it is a base that requires adjustment. We have not checked all bands and functions. I may have overlooked some parts. It has been remodeled with a general cover and a 50W reduction. Please be careful with off-band transmissions including the CB band. Please also visit BCL. It is one that can be used happily in the coming season when the high band is open. Since the FM unit of OP is not attached, FM cannot be used. S : New/Unused(Open box). A : Mint -Almost Unused. B : Excellent – Beautiful item for used. D : Good -Just fine. E : Imperfect -There may be a problem or shows sign of age. F : For parts or not working, untested, only powered on, needed maintenance, etc.. (Except for non-returnable items). International Buyers- Please Note. This item is in the category “Consumer Electronics\Radio Communication\Ham, Amateur Radio\Ham Radio Transceivers”. The seller is “luckysamurai-store” and is located in this country: JP. This item can be shipped to North, South, or Latin America, all countries in Europe, all countries in continental Asia, Australia.

Yaesu FT-840 Ham Radio HF Transceiver. I used this transceiver for several years before switching to a Kenwood TS-480HX. Since then, it has been in a closet in a non-smoking home and my wife is pressing me to get rid of my unused collection of ham gear. Accordingly, I have priced it to sell. The radio is in nice condition with only minor cabinet blemishes, which include a couple of scuffs on the main tuning dial being the only ones that are particularly noticeable (see front photo). The FT-840 would be a great HF rig for a new ham or a spare rig. I was unable to locate the microphone but the radio requires standard Yaesu 8 pin connector. The receiver is particularly good, and was used for both ham operation and SWL reception. These are the FT-840’s features as provided by Yaesu. 0.1-30 MHz Receive. Two direct digital synthesizers. And rotary encoder that provide silky-smooth tuning. The excellent general coverage receiver tunes. 1-30 MHz in 10 Hz steps. A 12 dB attenuator may be inserted for clear copy of very strong signals. The FT-840 uses a die-cast. With thermally switched fan to ensure full power output (up to 100 watts). The digitally synthesized local signals ensure clean, low-noise transmitter output on HF amateur bands. Backlit 10 Hz LCD. IF shift, reverse CW, dual VFOs, 100 memories, attenuator, noise blanker, meter, scan modes and speech processor. Only 9.5 x 3.7 x 7 inches. The item “Yaesu FT-840 Ham Radio HF Transceiver” is in sale since Wednesday, July 15, 2020. This item is in the category “Consumer Electronics\Radio Communication\Ham, Amateur Radio\Ham Radio Transceivers”. The seller is “jr77864″ and is located in Madisonville, Texas. This item can be shipped to United States.
