+ | ===== Operation ===== | ||
+ | {{ : | ||
+ | The wireless station SE-201 consists of the transceiver itself in a metal cabinet (14 kg) attached to either a battery case CS-79 (for portable use, HT / anode battery BA-39 and LT / heaters battery BA-40) or a vibrator voltage converter case PE-117 (for mobile use onboard a vehicle from a 6 or 12 V car battery). | ||
+ | |||
+ | The transceiver can be operated with a 4 m rod antenna or for onboard use on a vehicle with a 3 m whip antenna; a remote control set allows the transceiver to be controlled over fiel telephone line from a maximum distance of 200 m. | ||
+ | |||
+ | As standard communications range, a distance of 3 - 15 km is stated, that's a bit more then with a standard citizens band radio. | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | To operate the set, the microtel and the headphones normally stored in the battery case fpor transportation, | ||
+ | |||
+ | The switch on the right side is the volume contorl, the switch in the middle lets you select channels **A** or **B** (the crystals have to be plugged in the sockets on the chassis and the presetting prpceure has to be done before). The left switch controls the meter function, PLATE lets you control the plate voltage of battery BA-39), in position FIL(ament) the heaters voltage (Battery BA-40), the meter needle must reach at least the 2. In position OPER(ation) the meter does display the antenny current. While transmitting, | ||
+ | |||
+ | Transmit / receive switchin is done with the PTT button on the mikrotel; when the headphones are not plugged in, the set is wired for speaker operation. | ||

+ | ==== Development ==== | ||
+ | The wireless station SCR-610 has been developed by engineers of the U.S.Signal Corps in around 1940 and was produced by different contractors in the USA. | ||
+ | |||
+ | The complete station SCR-610 consists of the transceiver BC-659, the battery case CS-79, the vibrator poweer supply PE-117, mounting frame FT-250 anmd remote control RM-29 intended to be used onboard vehicles. | ||
+ | |||
+ | The portable version SCR-609 consists of the transceiver BC-659, the battery case CS-79 and the remote control RM-29 as an option. | ||

+ | ==== Field use ==== | ||
+ | {{ : | ||
+ | In the Swiss Army, the SE-201 / REX has been used as manpack or jeep vehicle station by the artillery. The 1510 units habe been faded out in 1974, many sets have been sold to vehicle enthousiasts, | ||
