Hi Hartmut, I got the same tuning problems as Patrick. After your patch the Pinnacle = 400e is not working anymore. I can get a signal, but no lock at all. I took a look at the PCB and there is definitely an LNBP21PD soldered = onto it. Your patch disables the modulation of the 22kHz signal inside the demod = as fas as I understood, but then the LNBP21PD was supposed to generate it. Unfortunately this is not possible with the Pinnacle 400e. I took a look = at the LNBP21PD datasheet which states, that DSQIN is supposed to be = connected to GND if you don't want the 22kHz signal to be generated by = the LNBP21 itself. Guess what?! Pin 14(DSQIN) is connected to GND. For the time being I reverted your patch on my local system and the = Pinnacle 400e is working flawlessly again.
