[Elecraft] Reciever Pre-Alignment

[pfb]

K2'ers,

On page 73 of the assembly manual -  I do not have a signal generator so I
have to use noise and a received signal but no matter what I try I "CANNOT"
hear any change when I turn L3 or L4.

I have tried this 3 times and my ears do not detect a change and I do not
want to damage the slugs in the cans.

Since I cannot perceive a change in 80 meters with L3 and L4 and I know that
these slugs are not real durable I have not attempted any of the others
bands listed in the sequence because I know that I will start toying with
them because it will bother me .....

Can anyone suggest some ideas on this step that I maybe able to correctly
set all these slugs and get this alingment done correctly?

Did I miss the boat here or is something wrong ?:

Thanks
