Description
Anordnung zur Erzeugung eines die Betriebsendeleistung übersteigenden Anrufimpulses bei batteriebetriebenen Funkgeräten Die bisher bekannten Anordnungen zur Erzeugung von Sendeimpulsen für Anrufzwecke, sind umfangreich und kostspielig. Sie eignen sich infolgedessen z. B. wenig für solche Funkanlagen, wo es auf Raum-oder Stromersparnis ankommt.Arrangement for generating an end-of-service power exceeding Call impulse in battery-operated radios The previously known arrangements for generating transmission pulses for calling purposes, are extensive and expensive. They are therefore suitable for. B. little for such radio systems where there is space or Electricity saving matters.
Die Erfindung sieht eine Anordnung vor, bei der auf besonders billige und raumsparende Weise für Anrufzwecke vom Sender kurzzeitige, die Betriebsendeleistun.g übersteigende. Impulse ausgestrahlt werden. Es ist eine Vorrichtung vorgesehen, in welcher ein Kondensator außerhalb der Anrufzeit an einer Spannung, z. B. der Anodenspannung, liegt und während der Anrufsendung derart in den Anodenkreis zwischengeschaltet wird, daß die Anodenspannung vorübergehend um den Wert der Kondensatorspa.nnung erhöht wird, wobei die Kapazität des Kondensators die Dauer des Impulses bestimmt. Die Zwischenschaltung des Kondensators erfolgt durch die Anruftaste unmittelbar oder über ein mehrstufiges Relais, welches eine modulierende. Tonfrequenz gleichzeitig einschaltet.The invention provides an arrangement in which on particularly cheap and space-saving way for calling purposes from the transmitter short-term, the Betriebsendleistungsun.g exceeding. Impulses are broadcast. A device is provided in which a capacitor outside the call time at a voltage, e.g. B. the Anode voltage, is and interposed in this way in the anode circuit during the call transmission that the anode voltage is temporarily increased by the value of the capacitor voltage is increased, the capacitance of the capacitor determining the duration of the pulse. The interconnection of the capacitor takes place directly through the call button or a multi-stage relay, which is a modulating. Tone frequency simultaneously turns on.
Das Verfahren der Erfindung zeichnet sich durch billigen Aufbau und einfache Regelbarkeit des Sendeimpulses aus.The method of the invention is characterized by inexpensive construction and simple controllability of the transmission pulse.
