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.
