The answer to your first question is likely no.  however, I believe 
that the old RCA TV radios had antenna jacks.  if this is so, you 
could possibly plug a digital converter box into it, and plug a set 
of rabbit ears into the converter box.  There was a radio sold by 
Radio Shack that looks alot like a Super Radio.  it has both VHF and 
UHF TV audio. It also has a standard cable connector on the 
back.  You could try hooking a convertor box to it, and an antenna to 
the convertor box, or if you have cable for TV access, try hooking it 
up to the cable.  otherwise, your TV radio will only work as a white 
noise generator on the TV bands after 02/17/09.
