An OTA station can't carry more than one HD stream; there just are not enough bits in 19.39 to do that.

Tell that to the ABC O&O's who shove the Live Well Network in HD on .2 and in SD on .3 so the channel is available to SD only customers since the cable companies refused to provide it to them if it was only available in HD. Word is that it was forced on them by the management despite the protests of the engineers. The CW 100+ group is also trying to get their affiliates to carry them in HD on .2 as well. The bulk of them use variable bitrates, so during rapid action motion scenes like sporting events the result looks like crap. WPVI is a nightmare when they have Big East on 6.1 and ABC's afternoon game on 6.2

Rabbit Ears has a list of all stations currently having at least two HD subchannels. (There's even a station in Maine that has 3 HD subchannels)

I live in centreville, VA....in the northern VA suburbs and have an HR34 and an HR21...both with AM21's attached. I have a Winegard TV antenna which is aimed at the washington DC OTA broadcast towers and it works great on both boxes.

You should have no problem at all receiving OTA channels from DC if you are in between Baltimore and Washington with the AM21.

If you disconnect your service can you still use the AM21?

You won't have any need for it at that point. Just connect your antenna to you TV in that case. The AM21 only serves to integrate OTA into your DirecTV service.

With no service, you have no active directv receivers, and no access to the AM21 features since it has to be connected to an active D* STB.
