Hi all,
I'm building K2 #5315, everything went well upto page 64 where I should do
the IF amplifier alignment.
It appears that there is no audio at all ( beter say very very weak ).
I cheked the earphones by hitting the SPOT , which was ok.
But I can not hear the 7000 internal signal at all.
When I tune my VFO there is definitely a signal and the S-meter runs very
well, especially above 7100 where all of those commercial staions are.
Checked the agc . I got 3.78 V on U2 pin 5 , that is fully CCW R1.
AF gain pot is approx 5 k , Rp6 (7-8 ) is 5K , R1 is 50K
checked 8R , D6 is 7.73 V and D7 is 0 V
All looks ok , anyone any suggestion ?
Cheers
Roger
