Good luck finding a battery operated DTV converter for your battery
operated analog TV. No such thing. I think there's finally a battery
DTV but it takes 10 AA and only lasts a couple hours. This is going
to have a real effect on Emergency Management.
http://rayvaughan.com/HDTV&EM.htm Ham ATV might just have a role here.
Right now the DTV USB stick on your laptop is a decent compromise.
I just put a DTV converter in my Prius. Doesn't work while moving due
to the doppler effect on the digital modulation, but when stationary I
get a great picture. Nice to see the NBC weather radar when I'm at a
traffic light.
Comcast changed to DTV RXs at their headend years ago. You could tell
when the audio on cable became a few seconds slower than over the air.
I'm sure the sat guys have done the same to get better quality. When
was the last time you saw impulse noise from lightning on satellite?
If a station's analog transmitter died today I bet less than 10% of
the viewers would even know.
Someone mentioned Cuba. When ducting is good, and the local Ch 6 has
transmitter trouble, we can sometimes see Cuba here in Miami. When
the local goes dark it's going to make for some interesting TV DX.

The Artec T3A-PRO does have a 12 volt wall wart. However it did not perform
as good as my DTVPal.
As stated in another post, article to come in a couple of days to our web

Me too! I will be posting a review of DTV converter boxes in about two days
on the ATVQ web site (www.hampubs.com) .
What I liked was the analog pass through (so I can monitor the ATV repeater)
and the DTVPal was more sensitive than the other one I tested (pickup up
more stations).
So, in a couple of days check out the web article.

I recommend the "DTVPal" - I paid a little extra for shipping from
cheapdigitalconverters.com, but it's in a different class from the GE
that I (wish I hadn't) spent my first coupon on at Target.

3a. Power limits on 70 cm

In Arizona we are restricted to 50 watts ithout a waiver from the San
Diego FCC office and Ft Huachuca but satellite work on 70 cm is exempt
as long as the antennas are pointed towards the sky.
Looks like the 100 W LPTV transmitters would not be legal here - not
that I can afford one anyway.

Of course all of the boxes are overpriced by about $40.
If I can get a DVD player for $29, $59 for a tuner is nuts.
Not even any moving parts.
Mark my word, the day the last card expires prices will drop like a rock.
If you haven't tried one yet, do it.
With an antenna inside my car, parked on a bridge about 30' above AGL,
I get stations 40 miles away perfectly.
Others are saying a roof antenna that was barely marginal for other
markets in analog get them perfectly with digital.
I wonder if it gets better when the analog 'noise' is gone from the bands.
Here's the official list of boxes.
Interesting that the list of the ones not available is longer
: https://www.ntiadtv.gov/cecb_list.cfm
If you're thinking car, RV, trailer or back up power source, this chart
shows models with 12VDC inputs:
http://www.ezdigitaltv.com/Additional_Features_Matrix.html
This is the one I used in the car. So far, I'm impressed:
http://www.ezdigitaltv.com/Venturer_STB7766G.html
Tip: Use channel add, not scan. So your list of stations gets bigger
and you never lose a marginal one from the list.

Not likely. The criteria used for interference to DTV from analog was so high
there is little likelyhood anyone would notice. There is visible DTV into
analog QRM in some areas of the Chicago market, and likely many others. The
noise floor of DTV is 15 dBc. vs 35-40 for analog. There is one new DTV tuner out
that actually uses the ghost energy to improve the noise floor, about 2 dB
max, as most lose c/n ratio when the equalizer flattens out the response to get
rid of ghost cancellations. And while DTV is p5 there is no P4, P3, P2, P1,
its P5 or nothing. A lot of folks are realizing they had marginal analog
reception and have stations that come and go with weather, foliage and passing
vehicles. There is 1 dB or less betwen DTV P5 and blue screen.

Here in Wisconsin I am seeing quite the oppisite!
I used to install towers for TV out here in the boonies.
Now it's all mini dishes
( Dish & Direct )
But many still watch via the transmitters, survey say about 30% still
get their Tv from the station.
But from all the converters we have been setting up for people, a P 4
to 4.5 is a MUST to get a semi solid lock on the digital side.
any lower than a P4 causes lock up and pixelation
just whats happening in the boonies here in wisconsin

That's what the design criteria was. = toa slightly snowy NTSC signal
contour.
(about equal to B grade) but a lot of places find coverage is a lot less.

What do you know about mobile reception of DTV? Is anyone doing
diversity inputs, buffering, or anything else that might help get DTV
while moving? From my testing in my Prius, over about 1-2 MPH it
totally dies. Seems like the ghost reception could help if the
processor was fast enough to compensate for quick changes.

DTV was not designed for mobile or portable use. It was not included in the
design criteria of the ATSC for digital TV systems. another government screw
up. But MPH and other digital services (read money for patent holders of
MOBILE TELEVISIONSERVICES) that use part of the DTV signal and are NOT compatible
with DTV TV sets has been developed so manufacturers can sell you more cell
phones, I-pods and other devices designed for MOBILE PORTABLE AND HANDHELD TV
service. Just Mike Microsoft develoeps Vista that won't work with a lot of
software, printers, scanners, and doesn't support Word help files unless you buy
NEW printers, software, scanneras. etc.
Its the Democrats in congress wanting more for spectrum auctions user tax
fees on telecom devices (my cell phone is now over $4 a month in taxes and the
base proce of $39.99 is actually over $72 with all the tack on fees and taxes).
The idea of a "robust" DTV system with lower bit rate compatible with regular
DTV fell by the wayside when manufacturers "discovered" thet had a hundren
billion dollar market for new MPH devices and services, and $300,000 per
transmitter for broadcasters to add it, plus the loss of a DTV channel to make room.
MPH takes up half the spectrum of an SD channel, and you can't send half of an
SD channel, so kiss one DTV channel goodby to add MPH.
Fox has already started about 30 experimental MPH channels to market multiple
program streams (think Fox Sports Net, or ESPN type stuff) and news to MPH
devices (Ipods, cell phones, etc). All for a SUBSCRIPTION FEE on top of the
equipment costs.
As I said in 1987, the DTV era will bring back PAY PER VIEW TV where nearly
nothing will be free anymore. The public has no idea how they are being
screwed.

5. Arizona HAM TV
Posted by: "William Munsil" wmunsil(AT)cox.net ars_k1atv
Date: Tue Aug 5, 2008 9:29 am ((PDT))
We are only co-ordinated for ONE 70 cm HAM TV freq in Arizona -
434.00 MHz.
There is one repeater that outputs on 421.25 but as I understand it
that was a compromise and no other HAM TV in the entire state can use
that freq.
All the rest - except one inband 1.2 GHz repeater - are crossband: 70
cm in and 1.2 GHz out.
All four of the AM channels are used - 1241.25, 1253.25, 1277.25, and
1289.25.
1265 is used as an FM input to the inband repeater.
We are co-ordinated for two channels in the 900 MHz band but no one
wants to use them so far as I can tell because of the Part 15 junk
here.
I have a 900 MHz PC Electronics two channel transmitter but no one
wants to get equipment to watch it.
Oh well.

One of my favorite TV DX stories....
I'm in Miami. But for a couple years I worked for a large cable
company based in RI. The cable headend in Fall River MA got heavy
co-channel interference on the Ch. 2 in Boston. I went there to take
a look. I thought no problem, NYC must be coming in. Co-channel
usually looks like a venetian blind effect on the channel. Dark
horizontal lines.
Turns out the Ch. 2 that was interfering with Boston was from my home,
WPBT in Miami. Apparently it regularly rides a duct caused by the
Gulf Stream.
Another tip... when you see co-channel on your local channel 2,
there's a good chance 6 meters is wide open.

I was always confused by line a. Couldn't make any sense of where hams
were and weren't allowed to operate.
Until I found a site on the internet listing which counties were fully
line a and which counties were partially line a
I can't find it now.

I used to live in AZ and all of the state has a limitation, now I am on lake
Hartwell just outside the circle of the limitation here in GA.
Here is the FCC webpage concerning the 50W limitations on the 70cm band.

Thanks, I never knew that, or I forgot. Never living that "high up on the
horse" it never was a concern. I always had to be worried about the 50w
limitations in certain areas.

Many of us that live near the Canadian border can not operate below 430MHz
on 70cm. I forget how far from the border "Line A" is but it cuts through
Michigan. We have one ATV repeater in western part of lower Mich that
outputs at 421, but we in the center part of the state and east can't
transmit there (not a problem because the inputs at 439.25). Areas like
Detroit are using 420 to 430 for public safety and maybe business band
stuff.
