Hello,

my BFO test failed (it shows 0.0000 Hz). After checking the right values of
the parts, I made some measurements with an oscilloscope. Here the results:
Between C174 and C173 : signal with a frequency of 8,06MHz (720mV peak).
Results @ RP6:
Pin2/Pin8 : no Signal
Pin4: 8,37MHz (116mV peak)
Pin5: 8,43MHz (42mV peak)

L33 seems to be ok(I made an resistor check of R16 : 1.5 Ohm)

Anybody an idea?

Thanks
