They have some nice oldies sometimes.

Here's what you can expect to get in one part of Whittier

(Your exact zip code and elevation may give different results.)

The lowest commercial channel you will get is the
faith-healer/preachy-movie channel reallocated from 40 to 23.

The *all will move below 52* statement in Platt's wasn't accurate.
While KDOC56 will move to 32, KLCS58 will move to 41,
and KOCE50 will move to 48,
**KCOP13 will move to 66 and KCET28 will move to 59**.

Careful. The channels you mention as "will move" are already operating
digital
on the "will move to" channels. Some will stay where they are.

At Transition, the four LA stations on analog VHF-HI channels, 7, 9, 11 and
13, will secure their digital UHF transmitters and initiate digital
transmissions on their historic (analog) channels.

After Transition, no so-called "regular TV" will be on channels 52 and
above. Other services have won bids for those channels. Qualcomm has
channel 55 for MediFLO mobile TV, etc.

Pls see http://www.rabbitears.info/dtr.php and scroll downpage past New York
to Los Angeles (they're in market-size order). See the fourth, fifth and
sixth columns for each station's FCC assignments: analog, interim digital
and final digital. It's all there.

I hope this helps.

Digital is a major step toward "conditional access".

So is analog. If you don't have the proper reciever, you can't pick it up.
Just a different format.


That's not what conditional access means.

The FCC and the TV broadcasters looked the other way because there is no
evidence that such activity has ever caused any interference. I can get 6
microphones to work in an occupied analog TV channel and neither notices the
other.

OK. I don't have a big problem with folks using frequencies they're not
assigned when there isn't an interference issue, although I also don't have a
whole lot of sympathy for those same folks if one day they *are* interfered
with by assigned users.

The TV Band Devices the FCC has recently begun the process of authorizing
are way more damaging than a 50 mW 65 kHz deviation FM signal.

What are the power levels? Presumably the occupied spectrum is potentially
many tens of MHz?

Luckily, these devices will not be allowed anywhere near where I work. The
FCC has banned them from the 13 biggest cities, and from within a kilometer
of a venue or stadium using wireless microphones. The proposed rules do not
require a Part 74 license for these protections.

If these are consumer-type devices, realistically how will the FCC stop their
use in those 13 cities? It'll be like GMRS where technically everyone's
supposed to be licensed yet, in actuality, I imagine that well under 1% of the
actual users a If the consumer can buy a radio off-the-shop at Wal*Mart,
there'll use it wherever they want, regardless of what FCC rules say.

Each TVBD will be addressable and can be shut off when it consults the
database. The top 13 cities thing is probably an oversight, but it's in
the proposed law.

The proposed power for a portable device is 100 mW, except on a
first-adjacent to a DTV station, which is 40 mW. This makes no sense
because the 2nd adjacent channel is more likely to interfere.

Thanks for the information, Dave.

The database is internal to the TVBD and indexed by a built-in GPS receiver
telling the TVBD where it is?

The database will be on the internet. How the device will connect to
the internet is not stated in the ruling, but if the device cannot
transmit until it has consulted the database it won't be by talking to
another TVBD.

Conditional access has been done with analog -- but not well. I sucessfully
defeated analog scrambling with two different home-brew devices but I never
tried digital. Too hard.

It's much easier to hard-code C/A with digital.

Just my two cents.

My current UHF antenna is a 14" Radio Shack clip lead clipped from the

Well, with this new Fascist "No More Free TV" crap, I'm gonna need
a real UHF antenna. My budget is exceedingly limited, but I have
a supply of materials (GTAW filler rod, with some coppery-colored
coating, so it solders like a dream, and is as stiff as piano wire)
to build an antenna with.

But I've been searching the web for some weeks now, and I can't
seem to find any kind of formula, except there was this program
I downloaded - LPDA.EXE, which runs on DOS. Unfortunately, it's
in Russian or Polish or Uzbekistani - one of those East Yurp
languages. Here's a screen snap:http://mysite.verizon.net/richgrise/...rog-Output.gif

Which I went through pretty much by-guess-and-by-gosh - can
anybody read that stuff?

There are a lot of factors I don't know about, like "Tau", and
all of the specific designs on the web are flat - something is
telling me I want one of those pyramid-shaped ones, but I really
don't know the difference (between that and flat) - it's probably
something to do with bandwidth or F/B ratio or whatever.

My local library has no ARRL Antenna Book (!), and did I mention
I have a seriously limited budget?

So, how do I pursue this? It'd be nice to have a program that will
calculate the whole thing for me, but am I dreaming? If I want to
send myself to Log-Periodic School, where should I start?

Or, does anyone have a UHF-TV log-periodic design that they'd share? :-)

Thanks,
Rich

TV has never been 'free'. you pay for it with every product you purchase
that is advertised on tv. and of course you pay for it in taxes, and also
in product purchases from sponsors, for 'public' tv channels. tanstaafl!
