Time to expand FM

[gr8oldies]

I don't forsee any move to create new analog frequencies, anywhere.

No more analog TV channels, of course.  But the scheme below makes perfect sense.  My sense is that most of the low-V DTV stations have chosen those channels just to comply with the FCC requirement to choose, but will request a move to high-V once everyone else has made their choices.

WBBM-DT in Chicago is an excellent example of why low-V is a bad place to operate a DTV.

Presuming low-V does get abandoned (or the FCC sees so few stations there it makes them move), there is going to be little demand for the vacated spectrum, but -- as has been proven in Japan -- it's perfect for a larger FM band.

How about looking at South Bend Indiana, where there isn't a single VHF station.   Their lowest channel is 16 and their channel lineup is:
16 WNDU (NBC)
22 WSBT (CBS)
25 WMWB-LP (WB)
28 WSJV (FOX)
34 WNIT (PBS)
46 WHME (IND-Religious)
57 WBND-LP (ABC)
69 WAAT-LP (IND)

I don't remember what their channel lineup will be once NTSC is gone, but I do know Weigel will have to get new channels for 57 & 69, and 28 will remain the same since their digital is 58 (which bumped WBND-LP to 57), and 28 will go ND (currently directional), knocking a LP station in Chicago off 28 since they use the -LP suffix on their calls.

I know for a fact that before the ch 3 in Kalamazoo Michigan signed on ch 2 for digital, WBBM-TV 2 was ok for viewing.  Since Ch 3 in Michigan started broadcasting on DT-2, WBBM-TV has been difficult to view these days, and heard the same thing in Michigan with WBBM-DT-3 interfering with the Ch 3 over there.  WTTW is vacating ch 11 once analog is shut off, and WBBM-YV applied for ch 11 once WTTW goes to UHF-47 fulltime.  But WBBM-TV will have far less coverage than WTTW does now because WLFI-18 in Lafayette Indiana has their digital on 11 and is staying on 11 after the transition.  But with WGN vacating their VHF too after the transition, maybe Univision might try to grab 9 since they're losing both their analog and digital channels for their Univision and Telefutura networks on 60 & 66 (don't remember their digital channels, but they're in the upper 50's).

Excuse me for butting in but... what a mess...

Are there any photos or movies posted online showing this?

Just curious, as I donj;t own a dtv receiver, and probably won't  in a long time.

I wish people like you were in charge at the FCC.

Huntsville AL is the same way with the exception of WTZT-LP on channel 11 (formerly on 28) of Athens

WTZT-LP 11 (IND)
WHDF 15 (UPN)
WHNT 19 (CBS)
WHIQ 25 (PBS)
WAAY 31 (ABC)
WAFF 48 (NBC)
WZDX 54 (FOX)

Folks, this is starting to turn into a discussion of television channel allocations instead of the potential to expand FM.

Back on-topic, please?
