LM7001 PLL-Sender

Version 1.0:

[Platzhalter Schaltplan]





160 * 100 mm
 

Es handelt sich hierbei um eine "Eigenentwicklung" mehrerer Teilnehmer des Senderbau-Forums auf dieser Seite.
Ich selbst habe diese Schaltung schon mehrfach so wie auf dem Bild oben zu sehen aufgebaut. Sie funktioniert also auf jeden Fall. Ob alle Bauteile wirklich optimal dimensioniert sind lassen wir aber erst mal dahingestellt, es wird sicher im Laufe der Zeit noch ein paar Änderungen geben (was dann an der Versionsnummer zu erkennen sein wird).
Der LM7001 ist eigentlich ein PLL-Baustein für UKW / MW-Tuner, der eigentlich nicht dafür vorgesehen ist, dass die PLL moduliert wird  (ähnlich z.B. dem SAA1057). In dieser Schaltung wurde das Schleifenfilter so weit verlangsamt, dass man eine für Normalnutzer ausreichende Modulationsqualität erreicht, schlechter als beim RDVV oder bei einer SAA1057-PLL ist sie jedenfalls nicht, mindestens genau so gut...

So ganz optimal ist das Layout nicht, es ist etwas fummelei beim Aufbau nötig. Aber es geht. Aufgebaut sieht es etwa so aus (Bild vom Prototyp):



Alle Bauteilwerte stehen im oberen Bild. Der Microcontroller ist ein 
Attiny2313, hier ist das dazugehörige HEX-File.
Der Takt muss auf 8MHz intern eingestellt werden! (und CKDIV8 deaktiviert sein!).

Die Schalterstellungen für die DIP-Schalter sind wie folgt:

Hinweis zu schwierig beschaffbaren Bauteilen:
Nur der 7,2 MHz Quarz. Disen findet man aber oft in alten Radiotunern, man kann ihn aber auch z.B. bei Bürklin bestellen.

 .......alles für den eigenen UKW Radiosender
