This is the Bad Religion cable FM which got moved a short while ago.

I'm a little surprised but it looks pretty similar to many modern FMs. CO line isn't as straight as in the aired ones and it has some darkish spots below but I can't see structures which would show lossiness clearly. Do these differences make it lossy?

that's a normal FM radio broadcast audio... it doesn't look any different when sent over CATV coax... the 19kHz tone there is the pilot tone that tells the receiver to process the mux using the sum & difference to produce two channels..

the 19kHz is normally filtered off by FM tuners, but if you recorded off the cable box or something, it wouldn't filter.

The limitation lower is the 15kHz FM radio bandwidth limit.

I wonder why this was pulled? The reason given is "this is one of those lossy digital cable broadcasts and is not allowed at the den (sorry).". But it's not from a digital broadcast, I recorded this from an analogue cable fm broadcast.

99% of all modern broadcasts are lossy, but we do allow them if they're taped open-air or "non-digital satellite" cable, i.e. if it has the carrier and looks something like the above screencaps it is allowed here regardless of lossy/lossless status since there is a predictable level of quality. on the other hand if its a webcast or digital sat radio you get from your dish the quality is all over the place and usually very poor.

in other words, it was a case of mistaken identity and I shouldn't have pulled this show, sorry about that. if anybody wants to re-up it or anything similar it is allowed here.
