====== Sangean ATS-808 ====== Manufactured by [[Sangean]], Taiwan. The world band receiver ATS-808, a microprocessor controlled travel radio with digital PLL frequency synthesis, was introduced around 1990 and was also sold as Siemens [[RK 661]] or under the Uher brand. {{:images:sangean-ats808.jpg?direct&600|Sangean ATS-808}} ===== Technical data ===== * [[Principle]]: [[Double conversion superhet]], [[IF]] 450 kHz / FM 10.7 MHz * [[Operation modes]]: [[A3|AM (A3)]], [[F3|FM (F3)]] * [[Frequency range]]: FM, LW, MW, SW (1.7 - 30 MHz) * [[Frequency display]]: [[digital display]], 1 kHz * [[Frequency memories]]: 18 memories * [[Signal strength indicator]]: LCD bar * [[Signal processing]] * [[Features]]: clock, timer * [[Sensitivity]]: [[A3|AM (A3)]] / [[Selectivity]]: kHz (-6/-60 dB) ==== Power supply ==== * [[Batteries]]: 4 x 1.5 V ([[UM-3]]), 2 x 1.5 V ([[UM-3]]) for quartz clock / memories ==== Dimensions ==== * 196 x 125 x 36 mm, weight 0.6 kg ==== Accessories ==== {{:images:sangean-ats808-front.jpg?direct&600|Sangean ATS-808}} ===== Operation ===== The Sangean ATS-808, or the Siemens equivalent [[RK 661]], is a compact pocketbook-sized double conversion radio which uses PLL frequency synthesis circuitry to cover the entire AM range from 150 - 29,999 kHz and the VHF range from 76 MHz (Japanese VHF band) - 108 MHz. The German version from Siemens only covers 87.5 - 108 MHz. {{ :images:sangean-ats808-back.jpg?direct&400|Sangean ATS-808}} The frequency can be entered directly with the numeric keypad, alternatively you can use the UP/DOWN keys or the tuning knob with two tuning speeds. The set does not have a [[BFO]] for receiving single sideband transmissions. The two settings of the digital clock can be set to local and world time. ===== Technical principle ===== Double conversion, digital frequency synthesis using PLL circuit. ==== Components ==== The set is equipped with semiconductors. ===== Technical documentation ===== ==== Development ==== {{gallery>:images?sangean-ats808*.jpg&0&80x80&lightbox&showtitle&titlesort}} ==== Further information ==== * [[https://www.radiomuseum.org/r/sangean_ats_808.html|Sangean ATS-808 on the website of www.radiomuseum.org]]
