+ | ====== SE-100 / FOX ====== | ||
+ | **Kleinfunkgerät SE-100 / FOX**; developed as **BC-611** by the U.S. Signal Corps and produced by [[Autophon|Autophon AG, Solothurn]] under U.S. Licence. | ||
+ | Shortly after the end of WWII, the Swiss Army acquired a quantity of the first U.S. made " | ||
+ | |||
+ | In Switzerland this set got the military designation FOX, after 1951 this has been changed to SE-100 according to the new naming scheme. | ||

+ | ===== Technical Data ===== | ||
+ | {{ : | ||
+ | * [[Principle]]: | ||
+ | * [[Modes]]: [[A3|AM (A3)]] | ||
+ | * [[Frequency range]]: 3500 - 6000 kHz, one crystal controlled channel pre-tuned; 50 possible channels with a channel spacing of 50 kHz | ||
+ | * [[Output Power]]: 0,027 Watt | ||
+ | * [[Sensitivity]]: | ||
+ | |||
+ | ==== Power Supply ==== | ||
+ | * [[Accumulator / Batteries]]: | ||
+ | The set is powered from a 1,5 V heaters batterie and a 103,5 V B+ / anode batterie; batteries will keep 10 up to 20 hours depending from the intensity of transmitter use. | ||
+ | |||
+ | |||
+ | ==== Dimensions ==== | ||
+ | * 80 x 320 x 90 mm; 2.5 kg (with batteries inserted) | ||
+ | |||
+ | ==== Accessories ==== | ||
+ | * Standard antenna is the built in **Telescopic antenna**, the set is switched on, when the bottom segment has been bulled completely out. | ||
+ | * **[[T-100|Prüfausrüstung FOX]]**, testing unit and set with an alignment cabinet in which the set's chassis has to be inserted to pre-tune the operation channel. | ||

+ | ===== Operation ===== | ||
+ | {{: | ||
+ | The U.S. made personal portable transceiver BC-611 got a very good reputation in World War II, it was the earliest really portable " | ||
+ | |||
+ | Like in a huge telephone handset the microphone and speaker are integrated in the cabinet of the set. The set is switched on by unscrewing the cover of the antenna and by pulling out the telescopic antenna. To talk, just push the " | ||
+ | |||
+ | The single transmission / reception frequency is controlled by crystals in the 3,5 - 6 MHz shortwave range, the frequency is written on a small tag on the cabinet and cannot be changed in case of co-channel interference. Later, the frequency channels have been coded by different label colours, to you just had to use two sets with the same frequency label colour. | ||
+ | |||
+ | The standard range is only 150 - 200 m under standard conditions, unter optimal conditions, the set might reach up to 1,5 km - malicious gossip has it that a powerful megaphone might be at least as useful... | ||
+ | |||
+ | ==== Alignment ==== | ||
+ | To operate on a certain channel, before use, a transmitter and receiver crystal, a tank coil and an antenna coil have to be installed on the chassis (these sets of components, four for each channel, are stored in the box BX-49), and after each change of operation frequency, a complete realignment has to be made. | ||
+ | |||
+ | So the Uem Ger Mech (signal troops mechanic) has to take out the chassis and has to install the four frequency dependent components on it (two crystals (TRANS (exactly on operation frequency) / REC (operation frequency + 455 kHz), two coils (the antenna and the tank coil)). For the realignment, | ||
+ | |||
+ | The **[[T-100|Prüfgerät SE-100]]** test set with a meter can be used for the alignment procedure and to control all necessary voltages and battery voltages, in the technical manual "Regl für UemGeräte Mech 65.5" you will find all the details (for english language, you might refer to the original TM). | ||

+ | ===== Technical Principle ===== | ||

+ | The portable transceiver **BC-611** respectively the wireless equipment **SCR-536** (consisting of the BC-611, the box **BX-49** with two crystals and two coils for twelfe different frequencies and the test set **IE-17** with the alignment cabinet) had been developed in around 1940 by a team working under Don Mitchell from Galvin Manufacturing, | ||
