I've been gearing up for the big ATSC switch.
I have a Hughes HTL-HD receiver. Works fine except that
it can't receive channel 32.1...no signal.
I have an outside antenna on a rotor...nothing.

I have two of these receivers that behave identically.

I have two other different brand receivers that work just fine on 32.1.

I've plugged the antenna into a spectrum analyzer and don't
see anything obvious. Plenty of signal. Bart's head is pretty
flat across the top of 32.1.

I have no idea where to start troubleshoothing this problem.

It's quite possible the problem is at the station.

If you have the same problem with more than one receiver of the same model
-- but other models work fine, on the same antenna -- then it does suggest
there's something about the bitstream the Hughes receivers don't like.
Possibly, the station is missing a metadata table or it's configured wrong.

What happens if you punch in channel 33.1 instead of 32.1? (33 is the
station's RF channel, sometimes if the remapping is screwed up it works if
you punch directly to the RF frequency)

How about if you try 32.2? (it's quite possible they aren't transmitting
a 32.2, but if they are and it works then the problem is definitely with
the station's configuration)

I wouldn't rule out calling the station and asking for Engineering. They
may not be helpful -- but they might.
