A trick I always do is to tune the radio to a station around 600 or 700 kc. Then adjust the osc (preferably if the radio has a slug on the osc coil) back and forth, adjusting the tuning as you go, until that station comes in fairly loud.

Now, if the set doesn't have a slug on its osc coil, you can do the same as above adjusting the osc trimmer, but you have to try to find a happy medium with sensitivity between the low and high ends.
