    Hello Friends, My name is Javier I live in Madrid Spain and I'm a collector of car radios. I prefer Becker, Blaupunkt and rare models of other manufacturers. The reason for entering this forum is to know if someone can help me with a problem in two of my radios, so far no one has solved it. I have two Blaupunkt, one is Bremen SQR 46 and the other is a Toronto SQR 48 both with the same error, there is a difference of 1.2 in the tune in FM and 36 in AM (see photos). I start from the same numbering on the dial to find the same station on both radios (top radio runs perfect, is used for comparison with bad tune in dial) and the result is the second photo (2, 4) for the same station. The top has the correct Radio tune in AM and FM. Someone knows how to make the adjustment? I think PL 06 and PL 02 (the FM and AM modules) are not faulty it must be something else before, as I am not technical in electronics I ask for your help or know where I can direct.
    Thanks
    Javier

    I have changed output transistor 2 pars one driver 2SC2314 and power 2SC2078 and it looks like now CB works, but I don't have all output power. What is strange on 1 channel I have 1W on 20 channel I have 1W also on "de" band 45 channel (26.605) I have 3,5W which is good. So, someone told me that even if I change output transistor of the same time CB must be tuned through some trimmer potentiometer or "pots".

    Hallo,
    du musst die ZF-Frequenz im Prozessor programmieren, damit die richtige Frequenz angezeigt wird.
    Viele Grüße
