Redsun RP3100

High-performance wide-band digital receiver with FM stereo, AM SSB reception.

An updated version of the Kaito KA2100 / C Crane CC Radio SW / Grundig S450DLX.  Updated with built-in SSB (no more clunky adapter) and what looks like many more features.

Redsun RP3100


■ Using the microcontroller (MCU) control, can control the display radio frequency, electronic time, radio received signal strength in different states.

■ The machine uses a large number of high-quality high performance integrated circuit chips and other electronic components, with the composition of the electrical performance of the radio  channel, with high sensitivity, anti-interference ability, background, low noise, low distortion characteristics.

■ The machine is divided into four bands:

  • FM range: 87.00-108.00MHz;
    longwave range :150-519kHz;
  • MW range :520-1710 kHz (10k system) / 522-1620 kHz (9k system);
  • shortwave range: 1711 – 29999kHz.
  • FM accuracy up to 10kHz, amplitude accuracy of 1kHz.

■ using a power-down feature to protect data memory (EEPROM), up to 1400 stored radio stations, including 400 ATS mode stored station, store another 1000 having single or multiple (up to 100) copy, delete, etc. editing functions.

■ with a wireless remote control, easy to use.

■ normal temperature (0 ℃ -50 ℃) display.

■ A variety of tuning modes: manual tuning radio automatically tunes radio stations and scan the storage radio frequency directly enter the station and other means.

■ Set FM and shortwave external antenna jack for remote receiver, you can also connect to local FM Cable Radio Network (CABLE FM).Wave set up a separate 500Ω external antenna / ground port, you can use an external antenna and ground to improve MW reception capability.
■ with FM stereo, AM SSB reception.

■ Setting the AM IF output can be used to extend the AM band other
functions such as: CW (amplitude newspaper), SSB (single sideband),
DRM (tone amplitude digital broadcasting), SSTV (Slow Scan TV) and so on.

■ AM take double-conversion PLL technology (IF 1 = 55.845MHz,
IF 2 = 455kHz), has a very good anti-imaging capabilities, shortwave superior to 40dB (100 times), medium wave better than 60dB (1000 times).

■ modulation using FET balanced mixer, high-frequency octave band pass
filter using, strong anti-interference technology, the AM has very good anti-jamming capability.

■ Ad hoc MW / SW Selectable wide / narrow IF bandwidth, but also according to the strength of the broadcast signal to adjust the high
amplifier gain (RFGA-IN), to get the best reception.

■ Digital knob (fast / slow / Lock) tuner radio frequency, with a convenient, fast function.

■ Dual timer beeps, boot Alarm function, countdown Alarm function, snooze function, programmable sleep timer function. Timer Start frequency setting function.

■ key tone function selection key lock function.

■ Setting the left / right channel line / input / output jacks. Can put the machine as a tuner, connect stereo amplifier, for better reception.The machine can also be used as the player, connect the external input audio signal.

■ optional 5-inch high-quality speakers and BTL audio amplifier IC, set up a separate high and bass adjustment knob, the use of different sounds to meet the color requirements.

■ display with backlighting, you can manually choose light / 8 seconds
lights out two kinds of illumination for night operation.

■ You can use an external AC power supply (220V) / external DC power supply (6-9V) / 4xR20 (large battery) / 4 AA (5 batteries) Battery four kinds of mode power supply, rechargeable battery rechargeable function.
