I have a perfectly good 27" analog tube TV...... but
only has one input....a coaxial input to the tuner.

In order to use this TV for SD digital reception I am
looking for a VCR or DVD recorder that has atsc tuner
but also has built in RF modulator.

Does anyone know if such units exist that are atsc and
can be used on ch 3?

nah, just get somebody's broken vcr from freecycle or the like and use
it as a modulator.
