O.K., Wendy - I understand this whole saga a bit better now: thanks.
Now I don't want to go on and on about this, nor do I wish to cause you any embarrassment, but from the above extract, you do say:
"The fault appeared to be mis-tracking".
It is the
local oscillator which tracks the
signal circuits,
not the 'other way round'. It was your way of describing the observed fault conditions that threw me (and others here) on to the wrong foot and caused a string of suggestions about possible faults on that L.O.
Anyway, let's move on. I (we?) now have a much clearer idea of what the fault actually is - and where the cause of the problem lies. So keep at it - I know you'll get there in the end.
