be built that does not do it.
So my experiment with the vintage UHF converter ahead of the DTV box was doomed to failure before it was even started.
Oh well... it was a fun afternoon anyway!

I have noticed a carrier about 0.310 mHz up from the low end of the DTV channels ... is this the carrier that you mentioned? This carrier is useful for indication of DX channels that a TV or converter can't receive.

Thanks for posting all the great info on the DTV process!
