Why is there no TV Channel 37?

There were a few Channel 37 allocations when the freeze was lifted in 1952, but I don't think any went on the air.
 
One CP, for WGOV-TV Valdosta GA, came the closest. I included their story in my own article on channel 37 at the UHF History site.
 
True, but I always wondered why the FCC didn't use virtual channel 37 as the solution to PSIP conflicts.

It should be KAXT-CD, digital 22, virtual 1

Yes, it was when that happened that I started wondering why the FCC didn't use 37 instead.

KAXT had a problem because in some areas both it and KRCB Cotati were receivable, confusing the PSIP decoders. I'm not sure if that is still the case, since KRCB moved to channel 5 in the repack and may not have any overlapping receivable areas. But I doubt the FCC would make "channel 1" change its PSIP now anyway, after many years have passed.
 
Does it really matter what PSIP "channel" is used, as long as proper RF spacing is observed and the PSIP number is not currently in use? Why not use anything between 1.x and 99.x if needed?
 
Isn't that how digital subchannels are already numbered?

How about numbering it like FM stations, like 99.5 or 107.3? :cool:

It would be a bit confusing, but I'd imagine the current PSIP would allow it.

It's not quite the same as FM are frequency numbers, and TV is channel positions. However, if the station wanted to, they could say they are on channel 90.1, and PSIP would support that. I think most TV's support up to channel 100, if I'm not mistaken, whilst others only check to like 70, while still others can go much higher.
 
You guys got me wondering so I accessed the ATSC Standards manual* and it says the range is limited to 99 for broadcast major channel numbers. So any set that won't scan channels 70 and higher is technically out of compliance with the technical specifications.

(*-I wouldn't recommend trying to read it unless you have some engineering knowledge.)
