KNMX, 540 AM, 0520-0538, 14 December 2016

[MDK2]

Tx in Las Vegas, New Mexico. At only 20 watts (per wikipedia entry), it's still the strongest signal audible on this frequency in Denver. QRM from CKB (a full 50 kW clear channel station in Saskatchewan) which sometimes rises up enough to be understandable, but mostly fades back while KNMX's Spanish mix dominates. Variety of styles including Spanish version of Jingle Bell Rock with YL vocals. Station ID at 0530.
