There is a small tic mark at the left of the lower scale on the main dial
(just below the 0.54 Mhz tuning mark)  Set the bandswitch to the 0.54 Mhz
range.  When the main dial is tuned fully clockwise that tic should line up
with the pointer.  Don't force it, just tune until it comes to a natural
stop.  If the dial is not pretty close to being on that tic mark, you will
have to mechanical adjust the dial position.  If it isn't on that mark, then
someone has most likely messed with it.  If it is on the tic mark, and still
not calibrated properly, RF alignment is necessary.

That is the point that the right logging scale should read "0", too.
