Glad to help inform!
It's generally accurate to say that basic cable isn't _switched_ digital, which isn't the same as saying it's analog.
It's not accurate to say that basic cable is analog - that is, a single channel can fit into a 6 MHz space. Some providers may put their whole basic lineup in analog, but this is decidedly not a technical requirement.
There's a difference between the little Comcast DTA (for receiving clear QAM digital signals that aren't switched) and a tuning adapter (for receiving digital signals that are switched).
For my company, some markets have no analog channels at all - basic cable services are delivered as clear QAM, and customers use a QAM TV, a DTA, or set-top box to receive them.
Other markets have some analog channels and some digital channels as part of basic cable - if you have an analog TV, you can only see the analog ones, unless you have a DTA.
