Digital TV transition question

[meanc]

How would I be able to find out if my TV has a digital tuner?

I have three that I'm mostly concerned with

1st RCA f36650
2nd JVC AV-27050
3rd Toshiba CZ27T31

Thank you very much in advance.

If you auto program channels for antenna and you get say instead of channel 6 you'd get 6-1. Looking at the model #'s safe to say none of them have the digital tuner built in. Go to,
