does this transceiver have a PI5V331 configured as a double balanced Tayloe Mixer if so then check the 74HC74 configured as a Johnson Counter to see if the quadrature switching signals are there or not if they are not then the problem might be the oscillator quadrupler might not be working as that is what drives the 74HC74 configured as a Johnson Counter to generate the quadrature signals that drive the PI5V331 configured as a double balanced Tayloe Mixer, this is just my thoughts on the problem as I don't have the schematics, That optional filter not being fitted didn't cross my mind.

"Nice" fault! Moral: always check for finger trouble first! Extra flux is not always a sign of "unauthorised" repairs. It is sometimes also a sign of FACTORY reworking (due to a poor soldering process during manufacture), and only discovered on test. Note also the extra flux on the filter legs. These and other delicate/expensive items are often fitted AFTER the board is soldered, in order to protect them from the radiant heat/hot air used to melt the SMD solder paste.

Kennst du noch einen seriösen Laden in Deutschland, der dieses Modell repariert? Oder vielleicht kennt ja einer der Mitkommentatoren diesen Effekt: WFM-Radio funktioniert. Auf allen anderen Bändern gilt: PKT & FM Rauschen aus dem Lautsprecher und S-Meter 0. Bei allen anderen Betriebsarten ist der Lautsprecher tot und das S-Meter hat Vollausschlag.

Puh, das ist eine ganze Stange Geld, zumal ich erst vor ein paar Tagen auf einer Webseite den 817 neu für unter 600€ gefunden habe. Da lohnt sich das Einsenden echt nicht. Eher schon eine gezielte Diagnose, obwohl mein Gerätepark nicht ansatzweise mit deinem mithalten kann. Vielleicht kannst du mir ja deine beiden vermuteten Fehlerquellen nennen, was meine eigene Diagnose vermutlich um Tage beschleunigte. Und immer schön hoffen, dass man alle benötigten Ersatzteile auch noch bekommt.

In general, I find the ideas and comments of clients interesting, but not to be relied upon when it comes to eliminating possibilities. It is precisely because they overlooked something, or assumed something which was not true.. that they come to us for help !
