Express Free Tecsun S-2000 FM Stereo LW MW SW SSB Air PLL Synthesized Radio s2000 World Band Receiver

Descriptions: —————————————————————————- FM receiving frequency range 76 ~ 108MHz, can be configured to China, Japan, Europe and frequency coverage, high-amp circuit with a tuning circuit 5 associated with the MCU control track tuned, high selectivity, anti-interference ability, choose IF circuit of the wide / narrow bandwidth, very suitable for long-distance FM reception (FM DX). AM received a double-conversion circuit applications, FET balanced mixer, high-frequency gain (RF) control, variable in bandwidth / narrow pass-band, multi-stage automatic gain control (AGC) technology, which greatly improved the ability to receive . The machine uses two antenna input attenuation control, inhibit the super signal interference from the antenna, to prevent saturation distortion, improve the reception. With background noise suppression (SQUELCH) function, inhibit the process of listening to background noise, this function is to listen to FM radio and keep listening to air band signal is particularly useful. With internal / external antenna selector switch and independent AM / FM dedicated jack. Special 455 kHz IF output (AM IF OUT) jack for external radio enthusiasts for DIY synchronous detector, software-defined radio (DSP) demodulator, DRM converter solution called 455kHz/12kHz other experiments. Has a very useful multi-function digital control knob can be used to set the time, adjust the frequency, select the memory page and address. Six kinds of radio stations: manual search radio frequency, direct digital frequency input, manual search stored radio station or directly enter the address stored digital, radio frequency automatic search preview, automatic station search preview stored. ATS using the machine function, automatic search memory FM, the spread to long-wave radio frequency. Radio can also use the auto-browsing, fast searching and store your favorite radio station frequency. The machine has a “by-band” and “cross-band” radio two storage methods, can store up to 1000 a total of radio frequency, which can be 500-bit address stored in the radio band (FM, shortwave, SSB, aviation band The 100 can be stored, the storage medium and long-wave 50); another 500 stored address bits for cross-band radio frequency, you can also have the flexibility to be divided into 10,20,25,50 pages, classified according to your preferences storage frequency. The machine uses 4-inch high-quality speakers, listen to FM stereo radio with headphones, you can adjust bass and treble tone, improved sound quality, listen to different programs to meet the needs. With left / right channel stereo line-out jack, external power amplifier or recording device. This machine uses 24-hour clock display, alarm sound with dual time, you can time on / off, listen to pre-set radio, buzzer alarm sound can be timed and can be set from 1 to 90 minutes automatic stop functions alarm ring. You can always start off smart auto sleep function (1 to 120 minutes). The machine can be used four large batteries or rechargeable battery, can also use the machine 220V AC power, or external DC power supply.
