+ | ===== Operation ===== | ||
+ | The complete set consists of an apparatus case with the actual transmitter and a battery compartment, | ||
+ | |||
+ | The receiver can be operated either from a combined plate (126V) and heaters battery (6V) or from a hand cranked generator, this generator needs always to be used during transmission, | ||
+ | The receive - transceive switching is done with the receive - transmit switch in telephony mode and automatically in telegraphy mode, one second after the last character has been keyed, the set automatically goes back to reception mode. | ||
+ | |||
+ | {{ : | ||
+ | The frequency is tuned with the large frequency switch - which also serves as a dial pointer - it drives directly the double variable capacitor of the transmitter and receiver. By squeezing the two buttons at the top of the frequency switch together, it is unlocked to be moved to set the frequency and snaps into 20 kHz stops when released. A knurled wheel at the top of the frequency switch is used for fine tuning of the frequency by +/- 50 kHz, the detent of the frequency switch is only released when the frequency correction is set to 0 kHz to prevent misadjustment of the transmission frequency. A " | ||
+ | |||
+ | Like in other Zellweger sets, the modes switch has the 0 position (for OFF) in the middle, for telegraphy mode it is turned to the left, for telephony mode to the right, and volume increases if the control is rotated clockwise for telephony. | ||
+ | |||
+ | When the transmitter is keyed, the antenna tuning must be set to maximum deflection of the antenna current instrument. The instrument can also be used to display the heaters and plate voltages. | ||
+ | |||
+ | The accessories compartment underneath the transceiver accommodates the combined heaters and plate battery, the headphones, the handheld and throat microphone. The transmit - receive switch is integrated into the frontplate as does the Morse key, the latter is folded in when not in use. \\ | ||
+ | Two headsets can be connected to the P set via a double plug. The switch on the microphone allows switching off of one of the two microphones. | ||
+ | |||

+ | |||
+ | The same hand cranked generator can also be used to supply the station [[SE-109|K1A]]. On the rear of the case, there is a compartment with some spare parts for the P station, a valve [[de: | ||
+ | |||
+ | Communication range is around 0.5 km in telephony and 2 km in telegraphy in unfavorable hilly terrain, under optimal (line of sight) conditions from an elevated position up to 12 resp. 15 km can be reached. | ||

+ | ===== Technical Principle ===== | ||
+ | {{: | ||
+ | |||
+ | In the transceiver module, the transmitter section is located largely on the right and the receiver section on the left. | ||
+ | |||
+ | The **transmitter** works with an oscillator stage with frequency doubler ([[de: | ||
+ | |||
+ | The **receiver** works as double conversion: The received signal is mixed in valve V1 ([[de: | ||

+ | ==== Development ==== | ||
+ | Based on the experience with the development of the station [[SE-107|K1]], | ||
+ | |||
+ | ==== Mission ==== | ||
+ | {{ : | ||
+ | In the forties, the signal platoon of an infantry regiment consisted of five radio patrols, each with two P-sets and four bicycles. | ||
+ | |||
+ | The station crew of a P station, the so-called radio patrol, consisted of 4 persons: a corporal as station leader, a radio operator, a clerk and a " | ||
