Tom, 

Did we all hit a nerve??  Hehehehe

Regarding the February changeover date - the FCC could still have set
another date in June 2009 (or April for that matter - anytime when the
weather in 2/3 of the country was a bit more tolerable) but *chose* not to
do so.  I deal with government on a daily basis in my primary job, so I know
that a LOT of times there is no rhyme or reason as to what dates are set for
anything - other than there was a blank spot on a calendar somewhere...
Also, DTV may have been around for 2 -3 years, but until late last year, I
was unable to find converter boxes that I wanted (with pass-through) locally
- so I ended up going online to get the ones I own.  Availability also needs
to be figured into the equation - and I'll accept *some* responsibility for
not beginning to prepare early enough - but the supply side also needs to be
considered.

I understand that you're in the business, and as you stated - it has been
the "Bain of your existence" lately.  Maybe a little less caffeine, or a
little more Jack Daniels will help you cope. (All in jest!!)

I do like the suggestion about the pre-amp - I may give that a try this
afternoon (if it isn't too cold in my attic!) and I'll report my results.
(BTW - mine is not a "hardware store" variety, it's a Winegard that I spent
probably $70 on about three years ago.)

The bain of my existance the last few weeks.....DTV.

Several Points of order: DTV Myths, Comments, Q&A:


I hear once a day: DTV doesn't work as good as analog.

My Response (based on experience): Does not work as good is from a point of
view. The fact is DTV is more effiecnt, the stations are typically running a
fraction of the output power and achieving the same footprint of coverage.
It takes far less signal to noise to pull out a clear, high quality picture
than it does with analog. Can you make out an analog station with a ton of
snow, lines, sparkles, etc when you might not pull in a DTV Station? Sure!
Do you enjoy watching a crappy picture? Do you like to listen to the guy on
his flea power portable noisy into the repeater or the guy on a good mobile
who is full quieting?


I hear once a day: The antenna in my attic/ my old antenna system does not
get the DTV stations that I get in analog.

My Response: Well, this is a technical group with a high level of RF
knowledge. How well does your 440 antenna (or any band) work in the attic
compared to on your roof or tower?
There is some implied responsibility on the part of the end user to ensure
that their equipment is optimized for the best performance. That being said,
I have many many clients with antennas in the attic that work just fine. 
What I do find to be the typical problem is that most people with antennas
in their attics have an amplifier installed to make up for being in the
attic. I'm sorry to say that the $15-20 amplifier you pick up at the
hardware store sucks, to prove that just bench test it on your specturm
analyzer & look at a DTV signal. They typically distort the waveform badly
and that is more common a problem why you can't tune the DTV station. I have
pulled those from an antenna system that were receiving analog but not
digital. Once out of the system, while the analog was virtually unwatchable
now (which the amp had boosted enough to tolerate), the DTV signal suddenly
came thru with flying colors! Would you put a crappy preamp on your repeater
receiver?


I hear once a day: My converter box does not seem as sensitive as my new DTV
set in the other room.

My Response: Let's use some common sense here. The government mandated that
the LOWEST COST possible converter boxes be made available for people to
convert their OLD analog TV's. The bottom line: You get what you pay for. 
Was not that long ago a wise jedi master here on RB posted findings on PL
circuits in radios with his test equipment and found that the cheaper radios
did a poorer job. Your $50 converter box is not going to have as good of DTV
tuner in it as your new $5000 Sony HDTV. This difference existed in analog
tuners as well. Nuff said.
*A side note: We have found that there are huge differences in converter
boxes. For what it is worth the Zenith model seems to be one of the best, in
case your shopping. I would stay away from brands you have never heard of at
the big box stores.

I hear every day now: The government screwed up & is running out of money
for the program.

My Response: We knew 3 years ago they only had so much money set aside for
this. What did everyone think would happen? There are a ton of unclaimed
cards out there right now, and as they expire they will put that money back
in the pot. However, it was always first come, first serve, and the
government should not be there forever to make sure you can still use your
dads 40 year RCA TV. And, it's $50-70 for a typical converter box. Holy cow.
If the $40 coupon makes the difference for you of eating or not that week, I
think TV should be less of a priority for you. (Sorry for the social
commentary)


I hear every day now (This one is yours Mark;) ): Leave it to the government
to make the change in Feb instead of June.

My response: If I remember correctly the orignal cutoff date was in a June,
but the lawyers fought & fought and got extension after extension. DTV has
been around for 3-4 years now in most markets, and we have known this date
was coming for roughly the same time. It's like high school: we knew for 2
weeks our paper was due, but still blamed the teacher when we were really
tired on the due date because we stayed up really late the night before
doing the paper. ;)

Finally- I cannot speak for all the markets out there, but here in Chicago
the DTV stations for the most part are at their full licensed power now,
only changes left to come are some channel re-assignments when the switch
happens. So go to work on your antenna that has been up for 30 years and get
it in shape again!
