CKJJ-FM is a Christian music radio station, broadcasting at 102.3 FM in Belleville, Ontario, Canada.

[2] On January 29, 2009, UCB applied for a broadcasting licence for 1480 kHz in Newmarket, which was the former frequency occupied by CKDX up until the 1990s;[3] it is unknown if this application was approved.

On September 10, 2009, UCB applied to change Cobourg's CKJJ-FM-1 frequency from 100.9 to 90.7 MHz.

[5] They would apply for it again on September 27, 2010,[6] this time receiving approval on February 21, 2011,[7] after the original repeater was forced to close down following the launch of CIYM-FM 100.9 in Brighton.

On June 16, 2014, UCB Canada received approval to add a new low power 50 watt transmitter at Maynooth, which will operate at 94.7 MHz.
