Hi all, I got a problem building my KX1: receive is OK, but transmit power is far too low (40 m < 2W, 20 m <0,5 W with 13,5 V). Of course, I checked and double checked solders, solder bridges, components and values. BPF and LPF are OK as measured with RF generator and oscilloscope. Output waveform good. Frequency right. Transmit voltages are all OK, but Q7's transmit base voltage is minus 1,1 V (minus) instead of the requested plus 0,7 V. Resistances and other components Q7 circuit are OK? 6V_2T is + 5,5 V. Q7 replaced Q7 without. Any idea will be welcome ! 73 Luc/HB9ABB/F6HJO
