The only loggings here on 1630 are KDIA and KCJJ.

Lafayette HA-600, Desktop Shortwave receiver | RigReference.com

Also caught KDIA on 1640. That Lafayette was the best 'budget' DX radio I ever owned.
Actually, it was the only budget radio I ever owned.

Nighttime: KCJJ.

I didn't know KDZR went off the air. The website is still up like it's still on the air. I suppose KDIA makes its way to the Rubbish Tip City like a ton of bricks at night now.

It appears to be on-again off-again lately. They've been back on the air for a few days now, transmitting Spanish music at very low modulation. Good luck finding a sucker willing to pony up the $750K you're asking for an X-bander nobody can hear when there's already a well-established For Music station on the air, serving the local Mexican diaspora.
