I'm building K2 #5020 and have no BFO. So far everything else works.
What I've done so far:
Checked for correct components - OK
Checked for correct orientation of parts - OK
Checked solder connections - OK
Checked for solder bridges - None found
Checked L33 - OK -Good continuity and no damage visible
Checked varactors D38 and D37 - Checks good as diodes
Checked associated caps - None shorted
Checked resistor packs - OK
Measured voltages at U11 -
Pins 1 thru 5 & 8 - OK
Pin 6 - 5.01 vdc - should be 6.1
Pin 7 - 4.66 vdc - should be 5.6
I also have no audio from the receive circuit. I figure this is due to
lack of BFO. The side tone works fine so I know the audio amp is
working.
Help!!
Thanks,
Tom WA7DET
