[Elecraft] [K1-2277} Front Panel construction -- R1 (10-turn potentiometer) numbering confusion

[Don Wilhelm]

Rich,

There are two types of 10 turn pots used - and therefore there is some 
possible confusion if you follow the pot numbering on the schematic. 
Use the illustration in the manual that matches your potentiometer.

If your VFO tunes in a direction opposite what it should, then you have 
something reversed with the pot wiring - no other harm will come of it.
