I don't have a channel 101 but do have a channel 99 at 117025Khz. It's an NTSC (VSB/analog) channel. I have a channel 135 at 861000Khz, also NTSC.
Joe, I'm a consumer, not an engineer. I have access to 2 digital TV's a Magnavox DVR and aftermarket iview STB and cable issued set top boxes, but have no idea where I would get the khz of my channels from any of this. The highest NTSC channel available since the conversion to digital is 22.
When I do a scan I get two channel 2, 3,4,5,6,7,8,9,14,16,17,19,20,22. One is Analog, the other digital. I delete the analog signals because they are blurry when compared to the digital version. So no matter what you may think, I'm not confusing NTSC with digital. Oh and the SD digital is definately blurry when compared to the HD that is coming in on the locals.
The only other observation I've noticed is that earlier you said,
My cable has three subchannels when an HD channel is present, 10 subchannels when SD is the only content, and 50 subchannels for music (at 480p). Only whole numbers are the lower 26 NTSC channels. The other 130 are clear QAM. I probably watch about 10.
My cable company has up to 11 SD sub-channels assigned to a channel when there is only SD content. The movement I've seen is where they seem to be trying to lower that to 10. So when they added a new major channel, they removed one channel from each of the channels carrying more than 11, and then sliding all the other channels to another slot. That time they changed 27 channel numbers. This last time they only changed 8. Hopefully things will stablize.
Your last sentence is what has me curious. What device says channel 200 is ABC in HD, and is it 720p or 1080i?
TV is 1080i, at 10AM this morning info on channel 200 ABC HD is coming in at 720i, 201 -CBS HD is coming in at 1080i.
