After months wihout any QSLs from LA stations this one appeared in the e-mail today:
#786: (HJJZ?) Radio 3:16 Bogotá 1310 khz verified my report. Angelly Sánchez, periodista signed the e-mail. The station appeared just a few days before my logging April 28. Probably a new name for Aviva 2. Thanks to Henrik Klemetz for helping me with the id.
