For anyone interested, the FCC Media Bureau AM Query page is located at: http://transition.fcc.gov/mb/audio/amq.html

The information they currently have for AM 1470 is as follows:
KRBR AM 1470 kHz ND1 Daytime D B LIC ESTES PARK CO US BL-19801031AE 1.0 kW 67483 WP BROADCASTING OF COLORADO, LLC

KRBR AM 1470 kHz ND1 Nighttime D B LIC ESTES PARK CO US BL-19801031AE 0.053 kW 67483 WP BROADCASTING OF COLORADO, LLC

It appears to me that the local LPFM has been more successful than 1470 AM in the past few years in attracting listeners. In certain ways, it seems to be programmed a little more like KSIR was in its heyday.
