Title: [solved] Version 6 IQ adjustment
Post by: WD8BXS on 10. June 2018, 21:23:40
Finished a new Version 6, no IQ adjustment! In which part of the circuit should I look ?

Where would likely bad solder joint be located?

Thanks,
Chuck

No IQ adjustment means:
- LO signals at mixer are missing / crappy
- IQ audio chain is faulty

Thanks Andreas,

Yes, I re-flowed around U11 and the Quad circuit, and that brought it back!

Thanks so much for what yo do!!!

Take care,
God Bless,
