- Date: ...March 1925...
- 882 kHz (...March 1925...)
- Mexico City, Mexico (...March 1925...)
- Owner of license:
- High Life (...March 1925...)
( Note: The station is shown in an April 1929 RADEX listing, operating at 800 khz under the ownership of Miguel S. Castro, but:
- A note from a reader in the same issue indicates that at least one other Mexican station had been changed from CZE to XFX, so this date is questionable.)
- Another CYH is shown in other publications (see below), in Monterrey, so the call CYH for the Mexico City station is questionable.)
