Hmmm.  VOR's may also have a steady un-modulated VHF carrier, but 
they are less powerful than analog TV carriers. I can't think of any 
other un-modulated VHF carriers.  Generally, when someone spends the 
money to generate a carrier, they add modulation to it.

There may be some carriers on HF, such as beacons and WWV, that have 
steady carriers with only a little bit of modulation, but HF bounces 
off of the ionosphere, and I assume that you want signals that don't 
do that, right?
