WebIC-737 & IC-737A. Symptom : RX/TX audio pitch change between USB and LSB, i.e. LSB has too many highs while USB has too many lows. RX audio may be "balanced" with the PBT control. Probable Cause: BFO or PBT oscillator is out of adjustment, or FL-30 filter is bad. Cure : Re-align BFO and PBT. If this does not correct the problem, replace the filter.
