On May 3rd, my K3 #1070 has been arrived from US after repair.
The TAT was 39 days including go & return transportation lead time.
According to the Elecraft's repair report, they replaced RF Board and confirmed all performances meet their published specifications.
HOWEVER, UNFORTUNATELY, I found that the K3 still has problem.
Very high noise and terrible intermodulation interference on all bands except 20m band is still observed.
I was totally disappointed.
Yesterday, I reported this info to the Elecraft's enginner who wrote the repair report.
Today, I received reply from Elecraft engineer and he is asking symptom. I sent all correspondences that I communicated with another Elecraft man before repair, since the symptom is not changed at all before and after repair.
