Chicago has a few of these
WOCK CD which is a low power on rf 4
13.1 Mundo Fox(Fox owns 2 full digital stations here they didn't put it on their o and o's)
13.2 KBC : Korean
13.3 Viera Living : Health and lifstyle in English
13.4 Weather Nation(changed from America One in January, this reminds me of The Weather Channel when they really did weather, not all the added shows)
13.5 Shopping : it was Mega Tv which got bumped for Mundo on 13.1. They might still have some mega programs, I don't usually check this one.
This station is very low powered and most people can't recieve it, I can and watch often for weather nation. It is a very weak signal I pick it up well when in town, people a block away can't see it. I wonder why Fox would put it here.
WPVN-LD
24.1 Retro tv network
24.2 Tuff tv
24.3 The Nashville Network
24.4 Polvision
24.5 Win Tv : Korean run by MBC, not the Australian station
24.6 MC tv : Religion in Korean
This station was purchased by Polvision when they were taken off WCIU 26.6. They were broadcasting from a suburb north of Chicago and now are on top of the new Trump hotel in downtown Chicago. This has improved coverage, I receive only slightly stronger reception from downtown than I did from the suburban location.
W25DW
25.1 HSN
25.2 I'm not sure exactly what it is, I usually see spanish language videos.
25.3 SBN : Religion in english
25.4 QVC : Shopping
25.5 LATV : Spanish language aimed at Puerto Rican veiwers(This station aired on WGN 9.2 and was pulled well before WGN added Antenna tv to 9.2. WGN and Antenna tv are owned by The Tribune Company)
61.1 Azteca : Spanish
61.2 CCTV : Asian, Chinese, Malaysion, some African programs have been seen.
Most of these I don't watch often so some information may be not be completely accurate. They are low power tv. At any given time infomercials are added on most.
These stations vary in strength depending on where in the metro area you live.
