Hmmm.....that, I don't remember, but when I have some spare time (we are 
building an addition to our home, which is taking up most of our time), I'll 
yank one open and take a look. I can't imagine how one could purposely 
reverse the direction of tuning, though

Correct. For instance, on 80 meters, at the indicated frequency of 4.0 MHz, 
the output of the LMO should be 5.0 MHz, and at an indicated frequency of 
3.5 MHz, the output of the LMO should be at 5.5 MHz.

The EXACT frequencies will depend solely on the frequency accuracy of 
your heterodyne oscillator crystals.

The same holds true for all the other bands too.

Sigh....yes....

My sincerest condolences. :-(

BTW, I have always considered those LMOs to be very beautifully built.
