Re: Strong carrier on transmit. #bitx40help



The carrier burst occurs because the c122 is charging up on TX through D15, causing the mixer to unbalance momentarily.

Solution is simple:

Cut the track from D15 and D16 common that goes to R38 and 39 and scrape the green paint off the cut track ends and solder a
0.1uF capacitor. Additionally add a 1K across C107 to provide a DC path.
