Hi Gary --
Thanks for taking the time to reply.
No, this is not the first thing I have done to/for this radio,
I have been working on this unit for a Year now and made many repairs.
Now that all functions are there I am doing final alignment. I have had
some experience with these radios, and have noticed that alignment is
sometimes needed though -- as you suggest -- not to solve a problem.
This particular alignment is necessary because the output and
receive levels vary with pto and pto vs tx offset selection. Not at all
according
to design specs!!

Please respond to

Just a guess but, generally, if a crystal oscillator has anything wrong
with it, it just stops oscillating. Ditto for PTO/VFO type oscillators.
Seldom are they "weak".
Are you aligning the radio just on principle or was the radio
malfunctioning? If it was malfunctioning, alignment is the LAST thing
you want to do, especially in a solid state radio. Again, generally,
alignment in a solid state radio does not change much unless someone
fiddled with it. Parts fail and you don't want to try to correct a
failed part problem with alignment! I'm new to the group so I am not
directly familiar with your radio's problems so please, if you can,
fill me in.
Gary
