DTV converter observations

It means that the black and white image will not have the crawling dots: its just like going back to the old fully black and white days!

The Channel Master box also has S video. And I use the luma portion for my B&W sets as described above. I modified my Channel Master CM7000 to produce B&W without chroma from its RF modulator:

Here I made the chroma switchable, so I can have color or B&W as I want.

I have both the Zenith DTT900 and DTT901 boxes. I've noticed a common problem with the DTT901 boxes is that when cold, often times the box will turn off after being turned on. (Power light goes blue, than goes back to red). On extreme occassions the box locks up and needs to be unplugged to reboot it. With the weather get colder, this has been happening more frequently. Has anyone else observed this with the DTT901 boxes?
