  Sende-Empfängerschaltung für Stationen zur drahtlosen   Naehrichtenübermittlung.   



   Für den Empfang von Ferngesprächen auf   drahtlosem   Wege finden, wie bekannt, Detektoren Verwendung, die infolge ihrer Empfindlichkeit nicht selten zu Störungen Anlass geben. Bei Gesprächsstockungen wurde daher zunächst der Detektor entfernt und ein neuer probeweise an seine Stelle gebracht, was nicht ohne Erschütterung des Apparates und damit

 Sprechens die Kontrolle für das richtige Arbeiten des Senders. 



   Diese   Übelstände   werden durch die   Sende-Empfängerséhaltung   gemäss der Erfindung beseitigt. 



   Zur Erläuterung des Erfindungsgedankens ist in der Zeichnung als Beispiel ein Schalter (in schiefwinkliger Projektion) nebst dem zugehörigen Schema für den Telephonstromkreis dargestellt. 



   Der Empfängerapparat E und der Sender S sind mit der Induktion J des Telephonstromkreises gekoppelt. Auf der Welle a, die-durch ein Handrad b drehbar ist, sitzen Mitnehmer e, Schalter d, e und g, von denen nur. der letztere als Schleppschalter Spiel hat.

  Transmitter-receiver circuit for stations for wireless news transmission.



   For the reception of long-distance calls by wireless means, as is known, detectors are used which, due to their sensitivity, often give rise to interference. In the event of stalled calls, the detector was first removed and a new one was put in its place on a trial basis, which was not without shaking the apparatus and with it

 Speaking the control for the correct working of the transmitter.



   These inconveniences are eliminated by the transmitter-receiver maintenance according to the invention.



   To explain the concept of the invention, a switch (in an oblique projection) is shown as an example in the drawing together with the associated scheme for the telephone circuit.



   The receiver set E and the transmitter S are coupled to the induction J of the telephone circuit. On the shaft a, which can be rotated by a handwheel b, there are drivers e, switches d, e and g, of which only. the latter has play as a drag switch.



  In the position shown, the receiver is switched on (antenna 1, e, kv 2, E, 3,

 the cam h1 of the switch d, the springs 11 and 12 are brought into contact; the cam h2 of the switch g has the same effect with the springs f4 and 15 '. When calls are blocked, the switch g is thrown for itself. The springs f4, f5 come out of
 EMI1.3
 to be able to monitor.



   For the sake of simplicity, only three detectors are shown in the drawing,

 Arrange detectors or the like.



   PATENT CLAIMS:
I. Transmitter-receiver circuit for stations for wireless communication, characterized in that with the help of a drag switch (g) attached to the shaft of the transmitter-receiver switch, a detector belonging to the telephone current for the

2. Anordnung nach Anspruch i, dadurch gekennzeichnet, dass mit dem Umlegen des Schalters aus der Empfänger-in die Sendestellung die zum Empfängerstromkreis gehörigen Detektoren abgeschaltet und ein zweckmässig weniger empfindlicher Detektor in den Telephon- stromkeis eingeschaltet wird, zu dem Zwecke, durch Mithören beim Sprechen das gute Arbeiten des Sendeapparates überwachen zu können. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 2. Arrangement according to claim i, characterized in that when the switch is flipped from the receiver to the transmit position, the detectors belonging to the receiver circuit are switched off and an appropriately less sensitive detector is switched on in the Telephonstromkeis for the purpose of listening in Speak to be able to monitor the good working of the sending apparatus. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
