      Klaus,
      You can hear the 22Mhz oscillator output on another receiver. If present, I
      would re-align the Pre-mixer, C64 and C66. If no signal is present, the Xtal
      could be at fault. But first inspect the contact fingers on the band module,
      Pins 18 thru 22, and make sure they are clean and not damaged.
      Lee, WA8QFE
