Re: QCX was OK #chat

Hi all, got my QCX up and running on 30m and receiving very nicely but only with about 1W power output on tx. I confirmed about 23V p-p on the drains of the PA transistors. I only get about 3.5 p-p on the gates, so it looks like low drive. The gate waveform is not a clean on-off but more of a triangular shape so that's not right either. On tx the rig draws about 350mW and the PA transistors get warm to the touch.

I've seen some similar issues in various posts, but so far nothing conclusive. Just wondering if anyone has found a fix to this.
