Matt,
If you can null out KRVN, 880 can be an interesting freq to DX from your TX location.
There are stations in Mexico as well as NM... KHAC, and CA... KKMC, but they run low power (NM) or beam away from you (CA) at night.
There is also a 1000 watter (nighttime) station in TX... KJOZ.
Here in MI, 880 is pretty much dominated by 50kw WCBS in NYC at night.
