+ | **Funkstation SE-206** (Autophon TR94/6); developed by [[Autophon|Autophon AG, Solothurn]]. | ||
+ | In the years after WWII and the fifties, a modernization of the wireless equipment of the Swiss Army was absolutely urgent.\\ | ||

+ | * [[Frequency range]]: 34 - 42,5 MHz, 86 channels with 100 kHz channel spacing | ||
+ | * [[Sensitivity]]: | ||
+ | * [[Output power]]: 0,6 W (battery powered), 2,5 W (with power supply SG94) | ||

+ | Further accessories are the hand cranked generator HG 94, it will generate the necessary voltages of 1,5 V (heaters), 51,5 and 103 V (HT / anode) and will increase the output power of the SE-206 to 1,7 Watts.\\ | ||
+ | A mounting frame MR 94 can be attached with the mounting frame rack MRG 94 on a vehicle chassis, it consists of a support of of the power supply and a drawer to store spares and the necessary tools.\\ | ||

+ | |||
+ | In addition, several test instruments have been developed for the SE-206/209 wireless set family. The battery tester **[[BPG83]]** is used to check the 1,5 V heaters batteries. The battery tester **[[BPG94]]** can test not only the round 1,5 V heaters batteries, but also the rectangular 51 and 101 V plate batteries. The test instrument **[[EJ83]]** is used to check eight important voltages in the set. | ||
+ | |||
+ | For servicing the sets, there were specific test sets according to the model number and frequency range: The test set **[[T-105]]** is used by the Signal mechanic to perform the alignment and checking procedures, the positions 1-8 of the test switch are the same as in the Eingrenzungsinstruments EJ-83. The dummy load **[[KA83]]** is used to test the transmitter function without RF radiation. | ||

+ | ===== Bedienung ===== | ||
+ | The transceiver **TR94** comes in a olive green metal case quite stuffed with valves (17 of them) and other electronic components. All controls are placed on the small face of the set. | ||
+ | |||
+ | The dimensions of the transceiver are 237 x 91 mm (w x h) and its dephth 345 mm, it's weight 11,3 kg. A canvas bag with all accessories (microtel, similar to a telephone handset) is attached like a backpack. | ||
+ | |||
+ | With three batteries of 1,5 Volts (ALN 10001) and five HT / anode batteries of 51 V (ALN 10051) or two batteries of 103 Volts (ALN 10103) and one of 51 Volt (ALN 10051), the R.F. output power is 0,6 Watts, with the hand cranked generator or the external power supply, it will reach 2,5 Watts. | ||
+ | |||
+ | The front panel has very few controls to simplify operation: at the left, You find the connectors for the microtel (handset) and the cable from the power supply, next to it the combined on/off, volume and squelch switch. The channel selector looks like a star, the channel number is mechanically displayed in a small window next to it, when divided by ten, the channel number equals the frequency in MHz. On the right hand, You find the antenna socket and the telescopic antenna. | ||

+ | ===== Technisches Prinzip ===== | ||
+ | {{: | ||
+ | The transmitter frequency results in the combination of the signals coming from the master oscillator (22 crystals with 400 kHz channel spacing in the range 45 - 53,4 MHz) and the so-called modulation oscillator (4 crystals in the 10,7 - 11 MHz range) - by combining these two oscillator outputs, the set can tune a number of 86 channels. | ||
+ | |||
+ | The audio signal from the microphone is amplified in modulator valve V11 ([[de: | ||
+ | |||
+ | The signal of the modulation oscillator already with frequency modulation of the speech signal is mixed with the siognal of the main oscillator (V14 ([[de: | ||

+ | ==== Entwicklung ==== | ||
+ | {{: | ||
+ | |||
+ | When the american surplus sets came to an end of their life cycle and spares were more difficult to obtain, the decision was made to develop a Swiss frequency modulated VHF radio. But the development of the [[SE-200|SE-200 (LUX)]] by [[Zellweger]] took more time. | ||
+ | |||
+ | So in 1953, the War Technical Dept. gave an order to develop a new transceiver for portable and mobile use for the infantry and motorised troops. In 1954/5, [[Autophon]] could already present a working prototype of their SE-206 (partly based on the rotary channel crystal drum as found in the [[SE-101]]) and won the contract for a first production run: these sets arrived at the troops for testing in 1956/7. After the immediate success of this transceiver, | ||
