Q13?? Please notice the designer numbers the transistors in groups -- so they are not consecutive except within a group.? as you look at the schematic you will see that the numbers begin with Q10, then after Q12 the next number maybe Q20.? its just a style to easily ID the subcircuits.??
make sure you have wired in the 4.7k resistor that is needed off-board for CW operation.? the sidetone in the stock unit is quite loud.? check things out using headphones to see what is working.? with v4 there isn't a lot of audio to drive a speaker.? if your receiver is working with headphones, that is a good sign.? a full sized antenna is needed for good receive -- purposely receive gain is scarce to keep the dynamic range very high.??
its a fine rig - be patient to figure it out and make sure all is wired correct.? there is a brief delay in keying CW.? very important - with one 4.7k resistor installed it will only work with a straight key.? to use a paddle, two different value resistors must be placed in each line from the paddle - this is documented somewhere on the web.??
