> Good morning Mike. I managed to zero beat using a steady RTTY signal yesterday. I am off by 1.5 kc. I know which dial needs to be turned, but unable to loosen up the chain enough to spin. With the unit flipped up to view the bottom upright, the far left chain needs to be loosened. Tried, but even a loose idler gives me no slack. If I loosen the screw in the yoke, can I slide the wheel forward a bit to give me the slack I need?
