[R-390] VFO End points

[Gordon]

Barry,
   It goes more then 1,000 kc. It just isn't accurate at the ends. The 
high end zeros at 3 past  and the low Zeros at 3 before which is a total 
of 6 off.
I'll try the End Point adjustment, but I am afraid if I lower the upper 
point by 3 to zero beat on 1,000 then the low end is going to zero on -994.
Maybe I'm wrong.
Will see.

Thanks,
Gordon
