Analog vs Digital TV during snowstorms.

Boggle? There is nothing like that in the UK. There is complete madness in the digital realm in that they still transmit the time signals but without any standard on the decode lag in the receivers the pips are anything from 1 to 3 seconds delayed. depending on the chipset. And if you have multiple digital radios in different rooms they each have their own delays leading to chorus echo effects when you can hear both.

Is there any standard for the signal strength in the new DTV era? I find that unless the nominal signal is 9/10 or 10/10 there are dropouts.

I'm not in a fringe area either. I have line of sight to the nearest transmitter about 20 miles away.

Why not try freesat or whatever they call it in the USA?

$125 a month? Ad-free? How many channels? Over here in India, I pay $4 for a 60-channel cable. Still analog of course.

Where? around here(central FL),you can't touch basic cable for less than $40 a month.

Around here $40 is "expanded" basic. You sure about your number?

I pay $102 for _everything_ but the sports channels... I have absolutely no use for feets ball ;-)

That's fools ball!

It's more like ~$25 in southern Oregon (Charter Communications). But the lowest-tier cable package is NEVER advertised, as far as I can tell -- you can to specifically ask for what their least expensive offering is; the lowest advertised package is expanded basic in the ~$40 range.

Do you want some idiot cop trying to send CW while driving at 90+ MPH?

That fits with what I see here in AZ. There's also a "seniors" package that's dirt cheap (also NOT advertised). ...Jim Thompson

I've done it in a Jeep at almost that speed. :-)

That's better than the idiots "texting" on their cell phones at freeway speeds! We see that all the time in California.

There is usually a lower level package availible, but the cable company isn't required to advertise it. I pay less than $20 a month for it. It is offered to low income, disabled and retirees, but only by request. It is 22 channels. That and Broadband Internet (at $49/month) plus taxes is $69.40 a month.

You know you had many _years_ to try this stuff out. In LA the major stations were on the air starting in fall 1998. I bought ours in December of 2003. Line of sight is not required but it helps a lot. Newer receivers have faster reaction to dynamic multipath meaning the adaptive equalizers can correct more quickly. Our OTA receivers (2 PCs with tuners and 1 Samsung set top box) have the older generation tuners and I have little problems and while it doesn't snow here, it sometimes rains like you wouldn't believe. Breakup is a very rare event. After spending a chunk of time with a spectrum analyzer (Tek

2712) observing DTV, the old tuners get cranky when there are dips > 10dB within a channel. Broad tilt seems a little less troublesome than dips, especially multilple dips. Stable is much better than changing meaning if you can find a reliable bounce you can be OK. I wish the tuner people would put a display that shows the amount of EQ processing required as that would be far more useful that 'signal strength' which by itself means little. FWIW the ATI HDTV Wonder tuners (2 on line) work reliably down to "50%" signal and they seem to agree with spectrum variations as observed on the Tek. By itself I don't find the ATI readout sufficient especially with reflections.

The closest I came early on was junking out somebody's unrepairable $5K set.

You know, the early plasma ones with only 3 year life span?

Of course I waited until 2009! LOL The $1500 one in 2009 was vastly superior and now sells for $1000.

GG > In LA the major stations were on the air starting in fall 1998.

And nobody noticed that the coverage sucked? How did this coverage issue get missed?

-Dubuque_IA.pdf

Notice the little yellow splotch over Cedar Rapids in Linn County?

That's the heart of the metro area I live in! Highest population density. "Coverage lost but still served by same network"

Why do I care about the network serving me if the coverage is lost? (but.. but... but... )

These yellow sploches are all over the country.

LA you said?

They left off the key for yellow on the first few stations? But they have sploches of yellow on the maps! LOL

On some at the top they show in text stats 0 persons lost yet they show yellow sploches? wierd.

Yellow Sploches mean "Coverage lost but still served by same network"

Apparently even the LA area has these dead spots.

It depends what you mean by narrowband! DVB-T in the UK uses CODFM with

16QAM before switchover/64QAM after switchover on 2K channels in an 8MHz bandwidth.

In practice, only 1705 carriers are active to provide guard bands between adjacent 8MHz channels.

So, each individual carrier IS narrowband, if that is the way that you wish to look at it, but it is still an 8MHz wide (combined) signal!

The 16QAM signals are transmitted at low power, as you say, to avoid co-channel interference with existing analogue services (and high power DTT transmitters as the Digital Switch Over rolls out across the country.)

As an example, my local (main) transmitter radiates four analogue services at 1MW ERP and six 16QAM multiplexes at 20kW ERP.

After DSO, the multiplexes will change to 64QAM at 200kW ERP.

For details of UK analogue transmitters see here:

Initial DTT Tx info pre-DSO:

Post DSO Tx inf:

Note that only main transmitters will carry six multiplexes, most relay stations will only carry three.
