Have a close look around the emitter of Q7 -it should be soldered
directly to ground so should never rise above 0v in Tx or Rx.

Hi SteveBeen taking some voltage measurements on IF/AF Board this morning, boy are they
weird.Q's 4-6 all show 11+ volts on the collectors when on RX not changing when in TXQ7
has 0 volts on collector in RX, should be 8.5v, in TX is correct at 0 volts, base is
fine on both TX/RX, emitter has 11.58 volts on RX, should be 0 and 0 volts on TX.Have
ordered Q,s 5 and 6, fitted Q4.with drive control fully CCW I am still getting 20watts rf
out in the tune position, I am assuming that is normal as it enables the op to tune radio
to antenna.Forgive all the questions please mate, I am only an ex rock ape ( RAF
Regiment) trying to improve my knowledge.regards73Snowy
