Monday evening (April 13, 2015), WOW removed all of the analog channels from their list of channels.
If you have a DVR from WOW you may not have noticed a difference. GHTV is still Channel 18. However, if you have cable directly connected to your TV, you will no longer be able to view GHTV – Channel 18 unless you re-scan for cable channels.
The new location for GHTV is channel 117-18.
Please contact WOW if you have any problems or questions.
