Q24: 5,76V
L33(left): 8,33MHz(240mV peak-to-peak)
L33(right): no signal (i think here is the lost)
I have to admit that I don't have a call sign yet, but I'm already learning
for the "exam" (I'm a student a had a lot to do the the last months..)
Thanks for your help

oh, i think i measured @ U11-P7 instead of P6. But when I measured again,
there was a signal with ~8.1MHz and 1.5V peak-to-peak.
U11-P7: no signal

Do you have voltage at the drain of Q24 when in CAL FCTR? You must
have voltage in order for the signal to pass through Q24.
If so, then trace the BFO signal with your 'scope.
Both ends of L33
Then through D37
Then to the gate of Q24.
Then the source of Q24.
Let us know where the signal is los
very strange... i measured again and now there is a signal with 8,1MHz at
U11-6 with 1,5V peak-to-peak...

Yes, its a K2 (sorry)
The internal counter probe works, already tested in the earlier tests
At U11 pin 6, I got a signal with 4.930kHz (2,4V peak to peak)
Any idea?

Name and call please - now required by reflector guidelines.
I assume this is a K2 - although you did not state it, it only makes
some sense with the K2.
Is the internal counter probe working? What do you get when in CAL FCTR
if you plug the probe into TP3 or TP1?

Hello,
my BFO test failed (it shows 0. 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)
