+ | **Patrouillenfunkgerät SE-105** / **P5 Set** or **Patrol Radio Set**; developed and produced by [[Zellweger|Zellweger AG, Uster]]. | ||
+ | The P5 set constructed by Zellweger, Uster, is the high power variant of the "P Geraet", | ||
+ | A very similar set has been in use onboard vehicles ([[SE-112|M5 / SE-112]]) and onboard a vickers tank ([[SE-113|T5 / SE-113]]). | ||

+ | The P 5 set (Infantry Patrol set) consists of a transceiver case with a battery compartment (weight 15,4 kg, with the battery 19 kg), a generator case (another 15,4 kg) with the hand cranked generator and spares and a canvas bag (5,7 kg) with material for a long distance antenna. | ||
+ | |||
+ | The receiver can be operated in the vehicle from the 12 V on - board power supply via the [[UM - 5 | Umformer UM5]] or mobile with a combined anode (126V) and heating battery (6V) or by means of a hand crank generator Transmitter or generator, a relay prevents the energy from being removed from the battery during transmission. | ||
+ | |||
+ | The set switches automatically from receive to transmit mode when the push-to-talk button is pressed or when the morse key is operated, one second after transmitting the last morse code letter, the SE-105 returns to receive operation. | ||
+ | |||
+ | {{ : | ||
+ | The huge frequency dial pointer also acts as tuning knob, it does directly operate the main tuning capacitor of the transmitter and receiver sections. Press the two pushbuttons at both sides of the dial pointer to move it, it will lock in 20 kHz steps mechanically. A round thumbwheel lets You detune the set for +/- 50 kHz, to move the dial pointer to another position, set the interpolation tuning knob to zero again. A rotary control " | ||

+ | As found in other [[Zellweger]] sets, the main switch has it's zero / off position in the middle, turn it to the left for telegraphy mode and to the right for telephony mode, the control also acts as volume control.\\ | ||
+ | Use the antenna tuning control to adjust for a maximum reading on the antenna current instrument when the transmit switch is activated; the meter can be switched to indicate the heaters and anode / B+ voltages, too. | ||
+ | |||
+ | The accessories can be stored in a compartment just below the transceiver chassis: the combined LT / HT battery, the headphones, the hand and the throat microphone and the morse key.\\ | ||

+ | The set's operation range is 3 km in telephony and 5 km in telegraphy mode in not very suited a housing area and up to 180 or 200 km from a optimum location on top of a hill. | ||

+ | ===== Technical Principle ===== | ||
+ | {{: | ||
+ | In the transceiver chassis, the transmitter is placed on the right and the receiver unit on the left side.\\ | ||
+ | |||
+ | In the transmitter, | ||

+ | ==== Development ==== | ||
+ | Based on their experience with the construction of the [[SE-108|K set]], the [[Zellweger]] company developed the low power patrol radio **[[SE-104|P-Gerät]]**. Because of the range, which too often turned out as beeing to small, [[Zellweger]] understood the call for a more powerful set and developed the **P5 set** with a transmitter output of five Watts in 1942, from 1943, the first infantry signal patrols could be equipped with the new set. In 1943/44, 575 units (or according to the documentation " | ||
