Read all About it!
The HF-2050 Receiver is modern in terms of operation as well as technology and performance. The extensive use of digital circuitry for signal processing and control affords the operator convenient command of the LF, MF, and HF spectrum. Front panel controls and displays have been thoughtfully engineered for quick access to all operating parameters of the receiver.
Tuning is accomplished by any of four methods: (1) The numeric keypad may be used for selecting frequency; (2) User preset channels may be recalled; (3) The rate selectable tuning knob may be used; or (4) Tuning may be via the digital remote control interface. A simple user code allows multiple receivers to be controlled from a standard video display unit.
Traditional analog IF amplifiers, filters, mixers, demodulators, and control loops have been replaced with stable and accurate digital signal processing (DSP). No IF alignment or fine tuning is necessary in production or throughout the life of the receiver. First-line maintenance is easily accomplished with the aid of Built-in-Test Equipment (BITE) which quickly isolates faults to the card/module level. DSP also makes it possible to further fault isolate to functional circuitry levels.
The HF-2050's superior performance is not limited to the DSP. Linearity is enhanced by the high performance front-end (25 dBm third-order-intercept) and ultralow noise synthesizer. Frequency stability is better than 0.05 parts-per-million per month. Other standard features include voice squelch, noise blanker, selectable AGC and audio mute.
