Overview
The R-5000 is a double-conversion general-coverage receiver with a first intermediate frequency (IF) of 58.1125 MHz and a second IF of 8.83 MHz. In FM mode, it uses triple conversion with a third IF of 455 kHz. It can receive AM, LSB, USB, CW, FM, and RTTY signals from 30 kHz to 30 MHz, with performance specifications guaranteed from 100 kHz up. The VC-20 VHF converter option extends the receiving range to 108 MHz to 174 MHz. The receiver features an IF filter switching circuit and a 0-to-30 dB RF attenuator to remove interference. It also includes an IF shift feature, an AF notch filter (not used in CW mode), and an AF peak filter (CW mode only). The phase-locked loops operate under microprocessor control, achieving high frequency stability and accuracy with digital frequency control in 10 Hz steps. Additional features include noise reduction, digital VFOs, direct frequency entry, memory storage for 100 channels, memory scanning, a built-in timer and clock, display dimmer, voice synthesizer option, computer interfacing, a rechargeable lithium backup battery, and a built-in AC power supply.
