[IC-7000] Transmitter Adjustment
toggle quoted messageShow quoted text
If the bias set properly for the driver and one of the PA transistors, it is very likely the PA transistor that won’t set is defective.

Subject: [IC-7000] Transmitter Adjustment
today I tried to adjust my IC-7000's transmitter according to the service manual but in step 3 (Final Idle Cur(HF/50M)-2) page 4-3, I found a problem in the regulation of the current so it does not change the current value and remains the same or changes very little (00 value = 1548mA that change to maximum 1610mA)
The problem occurs only in this step, in other steps all are OK
Any help please for what may be the problem?
