Information

The R-5000 is a double-conversion general-coverage Receiver with a first IF (intermediate frequency) of 58.1125 MHz and second IF of 8.83MHz. (In the FM mode triple conversion is used with a third IF of 455kHz.) It can receive AM, LSB, USB, CW, FM, and RTTY signals from 30kHz to 30MHz, with performance specifications guaranteed from 100kHz up. The VC-20 VHF Converter option extends the receiving range to 108MHz to 174MHz. Interference is removed by an IF filter switching circuit and 0-to~30dB RF attenuator. The Receiver also has an IF shift feature, AF notch filter (not used in the CW mode), and AF peak filter (CW mode only). The receiver's phase-locked loops operate under microprocessor control. High frequency stability and accuracy are achieved by a single-crystal system that provides digital frequency control in 10Hz steps. This includes the frequencies of the VHF Converter. Other major features of the R-5000 Receiver are 1. Reduction of many types of impulse noise controlled by two noise blanker switches and a noise-blanker level control. 2. Two digital VFOs (Variable-Frequency Oscillators). 3. Direct entry of frequencies thru the use of numeric keypad. 4. A memory that stores band, mode, and Antenna (1 or 2) information for 100 channels. 5. Memory scanning and ten types of programmed scanning. 6. A built-in timer and dual-time Clock. 7. Display dimmer. 8. The VS-1 voice synthesizer option internal installation. 9. Possible interfacing to a personal computer. 10. A rechargeable lithium backup battery for the microprocessor. 11. A built-in AC Power Supply (the Receiver can also operate on an external DC Power Supply.
