On June 21, 2017, WTIL bought from La Mas Z Radio, Inc. to Wifredo G. Blanco Pi, swapping
WBYM 1560 AM in Bayamon to La Mas Z from WTIL, in a three-way swap. The deal also involved International Broadcasting Corporation receiving land and equipment at the site of
WAPA 680 AM in Carolina, PR from Blanco Pi and permission to relocate
WGIT 1660 AM in Canovanas to that site and build a transmitter building, and IBC may sell or rent at $600 a month the WBYM transmitter site to La Mas Z Radio. On July 31, WTIL ended their local and Spanish Oldies format after 67 years of operation. When the transaction closed and awaiting the consummation, on August 3, this became the sixth radio station of the
WAPA Radio News Network. The sale was completed on August 15, 2017. The WAPA Radio Network now consists of seven AM and seven FM radio stations across the island,
