Moved to Philco Electronic Restoration by me.
Floyd, since 1540 is slightly above the design limit (1510-1520) of the 90's tuning range, you might be able to purposely misalign the radio just enough to make 1540 come in at the high end. This will throw off your dial scale on other frequencies, though.
I don't have any other suggestions right now, sorry. The only other alternative I can think of would involve a great deal of re-engineering of the radio circuitry such as modifying coils and such; which is not something I would want to do to a 90, especially the early version.
