NETWORK KNOWLEDGE had the first stations in the area on the air with Digital Television. Network Knowledge’s broadcast stations WSEC, WQEC & WMEC were on the air with both standard definition and high definition programming in the summer of 2002. We know that viewers (and Members) of NETWORK KNOWLEDGE have many questions about this new technology which is changing the way you watch television. The digital (DT) is offered FREE over the air. All you need in most occasions are an antenna and an ATSC (digital) receiver in order to view our over-the-air signal.   Though we encourage membership - no monthly fee is necessary to view our programming.

Network Knowledge has three different channels of programming available on its digital channels (channels 14.1, 14.2, 14.3 in the Springfield area; channels 27.1, 27.2, 27.3 in the Quincy area; channels 22.1, 22.2. 22.3 in the Macomb area).  A total of three channels of free television programming delivered to your home.

Digital television reception is more sensitive to atmospheric and terrestrial interference than was analog television.  On occasion a viewer might 'lose' reception of a television channel (the channel number no longer appears on the receiver).  Should this happen, and you have an indoor or outdoor antenna, try rescanning for channels.  This is essentially the equivalent of rebooting a computer.

Network Knowledge’s Digital (over-the-air) Broadcast Coverage area is represented on this map...

The transmitters and digital encoding equipment used by WSEC-DT, WQEC-DT & WMEC-DT are manufactured by Harris Corporation in Quincy, IL .
