I made the amplifier keying circuit. But my amplifer is not full break-in. I need a delay. The t-r setting is not doing it. It looks like the t-r setting is not affecting the 8R line. Now what? Oh, if you use 2n3903 transistors for Q1 and Q2 the 10K resistor on the base of the keying transistor is way too big. 1K works. Mike AB6CV
