John,

there are low-cost and readily available xtals for 11059 and 22118 kHz.
Devided by 22 or 44 this results in 502.69 kHz.
In the better electronics shop you might find 28224 kHz xtals, devided =20
by 56 =3D 504 kHz.
Even more exotic (but some kind of standard) is 49152 kHz, devided by =20
98 =3D 501.55 kHz

73, Rik  ON7YD
