This is what I get in 21-Pittsburgh if it helps with a decision:
RF/Analog----Call/City------------Market------Signal----Listing in EPG
25/2---------KDKA/Pittsburgh-----Pittsburgh---99-------YES
26/16--------WQEX/Pittsburgh----Pittsburgh---89--------NO
33/24--------WNPB/Morgantown--Pittsburgh---86--------NO*
38/13--------WQED/Pittsburgh----Pittsburgh---89--------See Note+
42/22--------WCWB/Pittsburgh----Pittsburgh---86--------YES#
43/53--------WPGH/Pittsburgh-----Pittsburgh---99--------YES#
48/11--------WPXI/Pittsburgh-----Pittsburgh---98---------YES
50/40--------WPCB/Pittsburgh-----Pittsburgh---85--------YES
51/4---------WTAE/Pittsburgh-----Pittsburgh---85--------YES
57/9---------WTOV/Steubenville---Whlg/Stbn---94--------NO#
+ Listings for WQED are on 13.3 when the video is actually on 13.2
* WNPB multicasts, 24.1 is West Virginia PBS, 24.2 is West Virginia PBS-2, 24.3 is PBS You and Annenburg/CPB
#(1) WCWB 22.1 is HDTV, 22.2 is an SD simulcast (no listings on 22.2 but is the same as 22.1)
#(2) WPGH 53.1 is HDTV, 53.2 is an SD simulcast (no listings on 53.2 but is the same as 53.1)
#(3) WTOV multicasts 9.1 is the regular schedule and 9.2 is doppler radar.
When speaking with other VOOM users WQEX, WTOV, & WNPB are the only digital stations users have reported as receivable, but not listed. Note that 2 of those 3 stations are in the Pittsburgh DMA, but aren't on the Pittsburgh channel map
