It is owned and operated by the Educational Public TV Corporation, a subsidiary of Daystar sister company Word of God Fellowship, Inc. WYDN's studios are co-located with those of local public access channel Dedham TV on Sprague Street in Dedham, and it shares transmitter facilities with Concord, New Hampshire–licensed Ion Television station WPXG-TV (channel 21) on Fort Mountain near Epsom, New Hampshire.
The station first signed on the air on May 5, 1999, as an affiliate of Prime Time Christian Broadcasting (now God's Learning Channel) as a straight simulcast of KMLM in Odessa, Texas.
[5] Originally licensed to Worcester, Massachusetts, WYDN operated its analog transmitter atop Asnebumskit Hill in Paxton (a site which is and has been used by Worcester area FM and TV stations since FM pioneer Edwin Howard Armstrong erected the tower in the 1940s) until the June 12, 2009, digital transition; its digital transmitter operated from the WBZ-TV tower in Needham.
WYDN sold its frequency rights as part of the Federal Communications Commission (FCC)'s 2017 spectrum incentive auction[6] and reached a channel sharing agreement with Ion Television O&O WPXG-TV;[1] it began broadcasting from WPXG's transmitter on April 23, 2018.
[7] As WPXG's broadcasting radius does not cover Worcester, WYDN changed its city of license to Lowell, Massachusetts.
