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. 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.
