I'm about 75 miles southeast of Dallas and lately I've noticed WBBM has been getting trashed by a Mexican station, XEWGR in Monclova, Coahuila. I've been able to get a positive ID and although the signal is somewhat variable it's often way on top on WBBM. According to official Mexican station information XEWGR is supposed to be running 10,000 watts day and 250 night non-directional. As mentioned here before, the end of daytime operation is a standard 8:00 PM local time throughout Mexico but I have heard them much later than that and I can assure you it's not a 250 watt signal.
WBBM is usually the most dependable Chicago signal here; WSCR suffers a lot of interference from Cuba, the same problem that WGN has but to a lesser degree. WLS has a horrible signal here but it's generally not because of anything in Latin America. The culprit is here in Texas, KVOZ Del Mar Hills/Laredo. As for WMVP I have yet to be able to receive it due to either KTOK Oklahoma City or XEOY in Mexico City. Usually "Radio Mil" on top.
