100% Feedback Seller Watkins-Johnson HF-1000 Premium HF Receiver with Preselector With original user / service manual. Video of Built-In Test (BITE)! CONDITION: Excellent High resolution pictures of actual item you will receive: VIDEO of BITE (Built-in Test) -> Passed! DESCRIPTION This is a perfect working and looking Watkins Johnson HF 1000 receiver. The radio comes with the original factory test sheet (dated October 31, 1994) and a complete maintenance manual. The Watkins-Johnson HF1000 is a fully synthesized general coverage receiver that combines analog and digital signal processing (DSP) to achieve a level of performance not previously available to the shortwave listener. The HF-1000 is based upon the WJ-8711 receiver made for military. Covering 5 kHz to 30 MHz with 1 Hz tuning and display resolution, the HF-1000 now provides commercial grade performance. Functions such a synchronous AM demodulation, noise blanking, I.F. filtering, AGC, demodulation, Beat Frequency Oscillator and passband tuning are accomplished through the use of DSP techniques. Filters with superior amplitude and group delay characteristics are achieved with digital stability and repeatability. An array of 58 I.F. bandwidths are available to allow the operator to optimize selectivity under any signal environment. Filters range from 56 Hz, for monitoring CW with exceptional signal-to-noise ratios, all the way up to 8 kHz for monitoring AM signals with maximum fidelity. Available detection modes are synchronous AM. FM, CW, USB, LSB and ISB. A tunable BFO can be adjusted in 10 Hz steps over a ±8000 Hz range, and passband tuning is available to further enhance the reception of CW signals. Gain control can be accomplished manually or automatically, with fast and slow AGC modes available. The squelch threshold is adjustable from 0 to -135 dBm, or it can be disabled. A noise blanking feature can also be enabled to effectively eliminate the adverse effects of impulse noise. A tunable I.F. notch filter allows the operator to reject undesired signals with the IF passband. The HF-1000 has an internal switchable preamplifier and attenuator, and analog S-meter, plus a built-in diagnostic self-test capability. In addition to fixed-frequency tuning, the HF-1000 provides fast, flexible scanning capability. Three scan modes are available: channel scan, F1-F2 scan and F1-F2 scan with lockouts. For all scan modes, the dwell time can be set from 0.5 to 20 seconds or infinite. In channel scan mode, 100 programmable memory channels are available. Sectors of memory can be specified for individual channel scans, allowing the available memory to be subdivided into multiple search scenarios. The operator can specify certain channels to be skipped without having to delete them from memory. Memory channels can also be single-stepped manually. In both F1-F2 scan modes, the step size is user-selectable from 1 Hz to 25 Hz. Included and installed in the receiver is the optional WJ-8711/PRE Suboctave Preselector (11 Filter Bands). It provides filtering of R.F. input spectrum to reduce broadband signal energy into the receiver. Tracking is fully automatic providing 11 separate filter bands. It can be bypassed. An internal speaker is installed.
