Hi Shorty.

Thanks for the input. It gave me a better understanding of the 045, 
046 and 047 codes. I did find the problem however. When you enter the 
event number, you must leave off the leading zero. Instead of 011, 
you simply enter 11. I wasn't getting any telemetry at one point, (I 
am not sure why) but when I did it was error 2, which is too many 
digits entered. I remember running into this same issue with one of 
the timer settings.

All is well now. I am courtesy tone free.

Thanks again.Johnab6li

[Repeater-Builder] GM 300 tone scan repeater

[Rocky Christie]

I have 2 gm300 units. I want to program 3 ctcss tones on 3 channels. Is there a 
way that I can get the Tx gm300 to follow the Rx gm300 in scan mode?

Re: [Repeater-Builder] GM 300 tone scan repeater

[Gareth Bennett]

As far as I'm aware, the easiest solution would probably be to add a third 
party tone panel such as a TP154 etc etc, programme to what tones that you want 
and re-insert into the TX GM300. Since you already have audio processing, the 
tone panel could be installed "Parallel" and be only responsible for CTCSS, 
making installation really easy!

Just my 10c

[Repeater-Builder] Motorola mobile radio timeline

[Bob M.]

Does anyone know of a radio "timeline" or a list of
all the mobile radios and when they roughly came out?
Since most of the great radios are now MD, there's no
need for an end-of-life date. I can make a guess at
some models, but there are so many that I've heard of
but never seen. This is just the kind of thing that
Motorola would have maintained, up until they got rid
of everyone who worked for them in the US last
century.

If this is already on the web, a link to it would be
great. If not, perhaps we can make one ourselves and
get it put up on the repeater-builder web site. I know
there are plenty of people out there who remember the
old Twin-V and T43GGV radios (I'm dating myself here),
Motracs, Micors, etc.

Thanks.

Re: [Repeater-Builder] GM 300 tone scan repeater

[Rocky Christie]

The thing is I was trying to do something without the tone panel. I have a 
repeater with 2 users and 1 with 3 users. I want to save the tone panels for 
the repeaters with 10 and more users. Panels are not so easy to come by over 
here. I had it in mind to have the Rx GM300 scan and ask for some help to make 
the the Tx GM300 follow the same Rx channel. (I don't have enough upstairs to 
solve this one.) I don't have a problem with talk thru as I will use the same 
circuit as the single channel repeater hookup.
Thanks, Rocky.

Most VHF analog stations are using UHF for their Digital broadcast.

Channel 6 Johnstown is 34 UHF
Channel 2 PGH is now on 25 UHF
Channel 4 PGH is on 51 (I think)

UHF stations have been allocated a different channel for their DTV
53 PGH is on 43 UHF  (I think)

While it was told that ALL VHF television would move to UHF, I don't 
believe that is going to be reality.  I could be wrong, however

No they have not switched to UHFdunno where you got that info?

Re: [Repeater-Builder] Off Topic (but with on topic questions): NTIA propaganda

[w7hsg]

Reality
Channels 2-13 will mostly be vacant.  There are a small number of stations that 
will revert back to their hi VHF channel after Feb 17.  Hi VHF channels 7-13.  
Here in Tucson only one station will revert back to their original channel. 
KGUN on 9.
Other VHF stations in Tucson, 4,6,11 & 13 are all going to stay on their UHF 
assignment.
On the UHF side, stations will pack the 14 through 52 spectrum.  Channels 53 
through 69 will be given up.
Broadcasters are really wanting this mess to be over.  My former station, KVOA 
is spending more than twice as much on elect, cooling etc running two 
transmitters.  One on 4 and one on 23.  The stations all want to stop the 
bleeding of money.
The only monkey wrench I can see is congress mandating that we do not turn of 
on Feb 17, 2009.  There seems to be some in congress that feel it isn't going 
to work.  Only time will tell.

I thought that the broadcasters would actually fight this, as there will 
definitely be a reduction in OTA viewership (hence ratings, hence advert. 
$$$) the second the analogs are switched off.  I own 5 non-DTV TVs (not 
including an old Watchman), & since satellite TV is unaffected I will 
probably forget the mostly useless OTA programming (I don't/won't pay for 
locals via the dish) & continue to watch std. def. TV via the dishes.

While a DTV signal uses the same bandwidth, several "channels" can be 
carried on one signal (I think they used to call this a channel "bouquet", 
don't know if the term is still in use).  So we will end up with the same 
amount of spectrum used for TV but with many more channels.

To each their own. I just dumped cable and went back to an antenna. It was 
time to replace our most-watched TV anyway. I don't think OTA will decrease, 
I think the opposite will happen.

Because digital TV broadcasting can cram multiple viewing channels in that
same 6 MHZ spectrum.

There is a DTV allocation in Harrisburg, PA for channel 2.

Originally, they were all going to be on UHF, but that changed.

Yes, PGH is all UHF. As I mentioned, look at Harrisburg's DTV
allocations. They have one on Channel 2.

(I pity their 6M activities as much as I rejoice PGH's channel 2 going
away)

Re: [Repeater-Builder] Off Topic (but with on topic questions): NTIA propaganda

I have yet to see any station share their DTV channel with another
station. (which would save spectrum)

So, there may be more content, but station WXYZ will still use the full
6 MHz. If my local area is any indication, they will simply add channels
such as full time traffic and WX. (like you need 6 channels of WX
forecasts)

I've still seen nothing to tie the DTV in with giving PS more spectrum.

[Repeater-Builder] Repeater TX/RX Problems

[ntoda96818]

Hi... currently I am running a Radius M120 RX and CDM1250 TX in my
repeater unit.  I was wondering what I could do to increase my
repeater's RX range.  It seems that my portables talking to the
repeater will RX on their end further then they can TX to the
repeater.  Is this a norm or do I need to get an add-on equipment of
some sort to equal the repeater's RX/TX distance?

Re: [Repeater-Builder] Re: Off Topic (but with on topic questions): NTIA propaganda

It would be interesting to know if the analog TV shutdown is going to occur 
in CA & MX.  If not, we might see a number of new analog stations across 
the border.  The Fox affiliate in San Diego is XETV ch. 6, & might end up 
being the only major analog TV station remaining after Feb. '09 
broadcasting for SoCal.

  I was looking at my local area, and there's at least one example...
in Springfield, MO, new DTV 44-1 will be the NBC affiliate, while
44-2 will be the CW (and 44-3 will be "Weather Now", I guess it's
a clone of The Weather Channel?)

  I was trying to prove or disprove our local (Joplin, MO FOX station
being simulcast on a DTV when they move, but I can't find it yet...
aah. Here, I found that the CBS affiliate, currently on 7, will move to
13, and Fox, currently on 14, wants to coexist on 13, but hasn't
gotten approval yet...

  Yup. Our local PBS stations will be running 4 channels on each of the
local DTV frequencies, the "regular", the HD, Kids, and You. Eeh...

> I've still seen nothing to tie the DTV in with giving PS more spectrum.

  You sure it wasn't the fact that they want to vacate the 700 MHz
chunk of the spectrum? Other than that, the only thing I can think of,
and boy is it a long shot, is that the FCC is trying to get _all_ the tv
off of channels 2 thru 6... nah, never mind. :-(

I can only speak for WIVB and WNLO there, but as far as I know all of 
the Buffalo stations were alocated UHF digital channels, and all have 
elected to stay on UHF. 

The decision to stay UHF, go VHF, etc depended a whole lot on the end 
result, ERP, propagation, and received interference all get into the 
equation. In one case my company gave up what was perceived as a 
great VHF alocation, in favor of UHF, but the VHF was ERP-limited, 
and was going to receive a pile of interfernce from a co-channel VHF 
DTV. So, instead, this station now will have 1000 kW ERP on UHF. 
Yeah, the electric meter spins faster. 

Many factors to consider, it wasn't easy deciding in some cases...

[Repeater-Builder] Re: Off Topic (but with on topic questions):NTIA propaganda

[Ben]

Here is a good list of what the channels will be like when the analog 
shuts off:
http://www.w9wi.com/dtvch/dtvch.html
  Many are going back to their original VHF channel. Here in Bowling 
Green, KY it looks like channel 13 will turn off their digital that 
is on 33 now and stay on the old analog channel 13 as DTV. In 
Nashville channels 4,5 & 8 will stay on VHF.

If you haven't tried to rx DTV yet it's time you did. I can watch 
channels now in studio quality that in analog are almost unwatchable 
by todays standards. HD signals are very nice too! It's easy to pick 
these channels up with the antenna you have up now and the cost is 
just going to do down from here. All TV's sold today are required to 
have DTV tuners. Go to Walmart and look.

Several channels in Nashville are running up to 4 or more services on 
one channel. Here in Bowling Green Channel 40-1 is NBC, 40-2 is CBS, 
13-1 is ABC, 13-2 is FOX, 13-3 is UPN(or what ever they call 
theirselves today), 53-1 to 53-6 are Kentucky Educational Television 
channels. They run PBS HD on 53-4...so many stations are broadcasting 
more than one service in that 6 MHz.

Anybody want the motran?  Free to first person at the gate in La Mirada, CA

Note, it has early Cal Crystal Labs xtals in the radio so who knows where they 
are now, much less if they will oscillate.

I am trying to think of the call sign of that old .76 - .525 repeater.  Does it 
still exist on a new pair?  All those receiver sites sure made it work good.

Far as I'm concerned there's no need to jam the airways with mind-numbing 
content from every hamlet.  A few 
regional advertising supported Ku band satellite channels should suffice.  This 
would free up a LOT of

RE: [Repeater-Builder] Repeater TX/RX Problems

[Eric Lemmon]

You are experiencing a very common problem- a repeater that is unbalanced,
meaning that its "mouth" is far more effective than its "ears."  A
repeater's coverage area is primarily determined by how well it receives
stations in the field, not by how much transmitter power it has.  Maybe that
sentence should be in capital letters.  Ironically, increasing the
transmitter power will sometimes reduce the coverage, simply because there
is more receiver desense occurring.

The Radius M120 does not have a stellar receiver, so you might try making
the CDM1250 your receiver and the M120 your transmitter.  The CDM radio has
far better shielding than the M120.  Use a service monitor to determine how
much desense you have.  One simple method is to disable the transmitter and
generate a test signal over the air (not into the receiver itself) that
gives you 12 dB SINAD at the repeater's receiver.  Then enable your
transmitter.  If the received signal deteriorates at all, you've got
desense.

Once you correct the desense, look at ways to reduce the attenuation of the
incoming signal.  Besides having a good antenna, properly positioned, your
feedline should (my Rule of Thumb) have no more than 1.0 dB of attenuation
at the receive frequency between the antenna and the duplexer.  In other
words, 200 feet of RG-213 is not a good choice.

Please elaborate on the details of your repeater installation.  What make
and model antenna do you have, and what is its height AGL and AAT?  What
kind of feedline, and how long is it?  Make and model of the duplexer? What
kind of cable is used for jumpers in the cabinet?

Subject: [Repeater-Builder] Repeater TX/RX Problems

Hi... currently I am running a Radius M120 RX and CDM1250 TX in my
repeater unit. I was wondering what I could do to increase my
repeater's RX range. It seems that my portables talking to the
repeater will RX on their end further then they can TX to the
repeater. Is this a norm or do I need to get an add-on equipment of
some sort to equal the repeater's RX/TX distance?

Re: [Repeater-Builder] GM 300 tone scan repeater

[Charles Schmell]

My only thought would be program the 3 rx freq. and
tones, and the scan list, with priority if needed. 
Program NO TX pl and switch JU 551 (Flat RX unmuted)
inside the receive radio, so it passes the pl,
hopefully through your controller.  Any IDs would not
have a PL, though.

Look on the FCC web site, link below.
Scroll down to:
"8/6/07 FCC Announces Final Assignment of Digital Television Channels."

Then look at appendix b & g to see the final assignments.
In the Pittsburgh area chan 13 will revert to 13 and chan 19 (currently
sharing chan 8s digital) will change to 11. Chan 8 will revert to 8 in
Johnstown.

Re: [Repeater-Builder] Re: Off Topic (but with on topic questions):NTIA propaganda

[MCH]

Many of my local channels are using tags that have the ANALOG channel
name. For example, while KDKA TV-2 DTV is on channel 25, the tag is 2-1
which is what you enter to see that channel. Either they are going to
move back to channel 2 or things are going to get even more confusing if
you have a channel 25 station you have to enter 2-1 when there is no
channel 2. What happens when a DTV channel 2 comes along (if that should
ever happen)?

4 (I forget their DTV channel) is using 4-1 and 4-2. 11 is using 11-1,
11-2, and 11-3.

[Repeater-Builder] New DB-224 w/water cooled phasing harness???

[kc4wdi]

We have installed several new db-224 recently. This particular antenna 
was inverted and has been in service less than 6 months.

While doing a routine test, I noticed the ref. power was a little 
high. The longer the TX was up, the lower the ref. power got; which 
typically indicates water in a connector or cable.

We found water in the connector at the center of the antenna. It DID 
NOT come through/around the weather seal!

The harness was carefully disassembled. Water (and corrosion) was 
found in the molded junction above the center connection.

Has anyone seen this before? Has the quality slipped that much on 
the new db-224's?

Any feedback is greatly appreciated!

Re: [Repeater-Builder] New DB-224 w/water cooled phasing harness???

[Steve Allred]

YES!
  Recently replaced a new DB-224 that had wicked water in the molded harness 
section and ended up inside the connector. Upon receiving a replacement 
antenna, we sealed the heck out of the harness with vapor wrap before 
installation. This one seems to be holding up for now, for now knock on wood. 
The local PD did not like a water logged antenna! 
   
  What happened to DB's quality? Upon inspection of the old one, it seems as 
though the "glue" that was suppose to be keeping the water out was not only 
sparsely applied but was also very brittle. Any movement of the harness would 
crack the glue resulting in a potential place for water to enter the harness.

I had a DB-224 that had been up for 20+ years and
found the same thing.  It was not upside down but one
of the coax center conductors had disentegrated inside
one of those moulded junctions.  I cut it open and
there was nothing left of the center conductor.

It is still in service with the top section of the
matching harnes replaced.

Stations want to identify by their old channel #.  They have spent years 
telling you to tune to Channel 4 or what ever.
The computer in your television set reading the digital code from the stations 
will take the channel 4 information and translate it to the correct UHF channel 
such as in Tucson Channel 23.  This special code is called the PSIP code and 
contains other information such as program playing and a TV guide for that 
channel. Also a lot other info.  It also tells the set if there is more than 
one program stream such as 4-2 might be weather, 4-3 traffic cam etc.  Current 
equipment will allow up to 4 std def channels in one Hi Def space.

Many of my local channels are using tags that have the ANALOG channel

which is what you enter to see that channel. Either they are going to

Along those lines...

If they are broadcasting one HDTV channel, can they have only two other
SD channels?

The translation doesn't do any good since you need to know the real
channel number before you can see their 'alias'. But, as I said -
confusion since Channel 2 is transmitting on Channel 25. People will
have to know to enter 25 initially to get channel 2.

Kinda like taking my 440 repeater and calling it "frequency 146.97"

RE: [Repeater-Builder] New DB-224 w/water cooled phasing harness???

By the way, you still must seal the connectors with a good tape like Scotch
33 first, then coat at least two coats with Scotchkoat.  Sorry for the 2nd

Hello All,

 

>From what I have seen the quality is the same but I have been preaching on
this board and others you can’t install a DB antenna without sealing every
screw, bolt, plastic knot, connector and anything else that could leak
water.  Besides that you must take all connections to the harness and
tighten all screws before you seal it.  Once you do that the antenna may
possibly outlive most people on this board.  I have a DB-410 in downtown
Fort Worth that I installed in 1976 and it still has flat SWR.

 

Use Scotchkoat from 3M to seal the antennas but don’t get it on you, it
sticks to you as well as it does the antennas.

Re: [Repeater-Builder] Off Topic (but with on topic questions): NTIA propaganda

[Mike Morris WA6ILQ]

There was a discussion on this topic a few weekends at the local
ham club after-meeting    all those that don't have to be awake
at zero-too-early in the morning to go to work wander over to a
local 24 hour coffee shop and discuss all kinds of technical topics.

One comment was that US military would really love to see TV
channels 3, 4, 5 and 6 vacated.  That drew a bunch of "huh"
comments, and some head nodding from others.

It seems that 66-88mhz is used by the military in much of the world.

In the USA the 60-66MHz range is television channel 3, the 66-72MHz
range is TV channel 4, the 72-76MHz frequencies are used as
"Operational Fixed / Repeater" frequencies (essentially commercial
point-to-point links), 76-82MHz is TV channel 5 and 82-88MHz is TV
channel 6.

Might want to keep that in mind... lets see how many areas have
3, 4, 5 an 6 freed up.

Re: [Repeater-Builder] Re: 10 meter split site

[Paul Plack]

Greg, antennas affect transmit and receive equally, so the user's poor antenna, 
or the repeater's good one, has no real bearing on alligator/elephant effect.

Achieving balance in a system requires accounting for the noise environment, 
and the mobile is likely to have much more noise than the repeater location, 
due to vehicle ignition and electronics nearby. The noise problem will be a 
bigger factor on 10m than at VHF. 100 watts on the repeater vs. 25 watts in the 
mobile is a difference of only 6 dB, which is probably very reasonable for 
compensating the system for mobile noise and preserving balance.

73,
Paul, AE4KR

  Hi Steve,

  I have 2 1/2 mile distance between my receiver and transmitter on my 
  10 meter repeater, and have no desense on the receiver. One of the 
  important things is that the receiver has a high dynamic range. I am 
  using a Micor receiver because of its ability to reject nearby 
  signals. 100W is kind of high power for a local 10 meter repeater. 
  From your location 40 to 50W is plenty of power, at that elevation 
  and should give you coverage from Redding to Fresno, and the lower 
  power level will help on your receiver defense. Don't forget that 
  your users will probably be using Radio Shack mobile radios that on a 
  good day can barely make 25W, and there antenna is not as good as 
  your repeater antenna. After all, you do not want to end up with an 
  alligator, but with a balance system that matches your users ability.

RE: [Repeater-Builder] New DB-224 w/water cooled phasing harness???

[Paul Finch]

Hello All,

 

>From what I have seen the quality is the same but I have been preaching on
this board and others you can’t install a DB antenna without sealing every
screw, bolt, plastic knot, connector and anything else that could leak
water.  Besides that you must take all connections to the harness and
tighten all screws before you seal it.  Once you do that the antenna may
possibly outlive most people on this board.  I have a DB-410 in downtown
Fort Worth that I installed in 1976 and it still has flat SWR.

 

Use Scotchkoat from 3M to seal the antennas but don’t get it on you, it
sticks to you as well as it does the antennas.

YES!

Recently replaced a new DB-224 that had wicked water in the molded harness
section and ended up inside the connector. Upon receiving a replacement
antenna, we sealed the heck out of the harness with vapor wrap before
installation. This one seems to be holding up for now, for now knock on
wood. The local PD did not like a water logged antenna! 

 

What happened to DB's quality? Upon inspection of the old one, it seems as
though the "glue" that was suppose to be keeping the water out was not only
sparsely applied but was also very brittle. Any movement of the harness
would crack the glue resulting in a potential place for water to enter the
harness.

We have installed several new db-224 recently. This particular antenna 
was inverted and has been in service less than 6 months.

While doing a routine test, I noticed the ref. power was a little 
high. The longer the TX was up, the lower the ref. power got; which 
typically indicates water in a connector or cable.

We found water in the connector at the center of the antenna. It DID 
NOT come through/around the weather seal!

The harness was carefully disassembled. Water (and corrosion) was 
found in the molded junction above the center connection.

Has anyone seen this before? Has the quality slipped that much on 
the new db-224's?

Any feedback is greatly appreciated!

Not really...you can have the tuner do a scan of the available channels and 
then they will show up as the "virtual" major channel...the same as the 
associated analog channel...along with the minor channel multicast indicators.

Re: [Repeater-Builder] Re: Off Topic (but with on topic questions):NTIA propaganda

[Hap Griffin]

However, in their infinite wisdom the FCC has made it MANDATORY that stations 
identify themselves in the PSIP (what you see on your digital tuner) with their 
ANALOG channel number.  I'm Chief Engineer for a network of eleven stations and 
we have two that have the analog and digital transmitters on different 
bands...i.e. analog on UHF and digital on VHF.  Thus, there is a huge amount of 
confusion when someone see's digital channel 29 on their tuner, when the actual 
RF is on channel 9 and they don't have the proper antenna for reliable 
reception.  It's gets even crazier when the analog transmitters are turned off 
in February 2009...the digital stations will be branding themselves with a 
channel number that is completely unrelated to reality.  Then, believe it or 
not, it gets EVEN nuttier after a few years and another station wants to come 
on the air and request your old vacated analog channel.  They will have to 
identify themselves as your actual digital channel number...completely 
unrelated to their actual digital RF channel.  Really smart of the FCC, eh?

  Stations want to identify by their old channel #. They have spent years 
telling you to tune to Channel 4 or what ever.
  The computer in your television set reading the digital code from the 
stations will take the channel 4 information and translate it to the correct 
UHF channel such as in Tucson Channel 23. This special code is called the PSIP 
code and contains other information such as program playing and a TV guide for 
that channel. Also a lot other info. It also tells the set if there is more 
than one program stream such as 4-2 might be weather, 4-3 traffic cam etc. 
Current equipment will allow up to 4 std def channels in one Hi Def space.

I don't know what is going on where you are but here in 
florida I hit 2-1 on the remote and get what is on analog 
2 but in digital.  I hit 2-2 and get the NBC local 
weather.

I don't know what all of the stress is over this.  I think 
digital tv is great and this should have been done a long 
time ago.  My father-in-law refuses to get cable or 
anything like that so we gave him money towards a new TV a 
few months ago for his birthday.  He went from getting 3 
stations that were OK to watch and maybe 8 more that 
either were things that people don't want to watch or so 
fuzzy that I would rather have a root canal than try to 
watch it, to 31 stations and growing that are crystal 
clear.  Top that off with the fact that he loves PBS and 
now has 5 PBS stations.

So no matter what happens to the spectrum the overall 
result is going to be good for everyone.  I personally 
think that the whole issue of making sure that everyone 
has time to get new TVs or set top boxes and the 
possibility of subsidies to help people pay for set top 
boxes is bogus.  No one gave me a free CD player when they 
stopped making tapes.  No one gave out free FM radios when 
90% of the content moved off of AM.  You can get a SD 13" 
TV with a digital tuner for $99 and I for one would rather 
watch that than a 20" fuzzy analog tuner.  That is what I 
put in my daughter's room because I didn't want to pay for 
another DirecTV box for her room and she is happy with it. 
 Also guess what she is 9 and has no problems working the 
2-1 style tuner.

they go all digital.  From what he said, I believe most or all of the local
VHF stations plan to go back to their VHF channel.

His reasoning was simple, they get much better coverage for the same power
level on VHF channels over UHF.  To get the same coverage on UHF requires
much more power hence more expensive TX equipment, higher electric bill and
higher maintenance costs.

As far as freeing up spectrum, I think it is just semantics.  Right now
almost all stations are running two TX on two different frequencies one
analog one digital.  When they go all digital, the stations all go back to
one TX on one frequency so half of the channel frequencies currently in use
will be come unused and available.  The fact that all those channel
frequencies were already allocated for TV use prior to starting the digital
conversion just seems to be forgotten in the propaganda.

Re: [Repeater-Builder] New DB-224 w/water cooled phasing harness???

[Paul Guello]

If by inverted you mean the antenna is mounted upside down then the drain holes 
for condensation are pointing up instead of down.  And the water trapped inside 
would not be able to drain out.  Paul

 We found water in the connector at the center of the antenna. It DID 
 NOT come through/around the weather seal!
 
 The harness was carefully disassembled. Water (and corrosion) was 
 found in the molded junction above the center connection.
 
 Has anyone seen this before? Has the quality slipped that much on 
 the new db-224's?
 
 Any feedback is greatly appreciated!

[Glenn Little WB4UIV]

The numbering of the digital channels is to help the people that know 
nothing of TV past turning it on and changing channels. The station that I 
work for is channel 4. Our digital transmitter is on channel 34, but, the 
viewers know it is 4-1. That way they do not get lost in the channels. I do 
not know of any of the sets that display the real digital channel. I guess 
that some may, if, you really dig into the menus.

So for now, the viewers of analog channel 4 know the digital channel as 4-1 
and not the real channel of channel 34.

As far a new digital channels, all bets are off. You will have to ask the 
lawyers at the FCC as they no longer have many technical people on staff. 
They have found it a much more lucrative business of selling commodities 
that they do not own than helping to further the use of the RF spectrum. 
Look at the mess that allowed Nextel to get away with.

We will see what happens when the analog channel turn off date passes.

[Repeater-Builder] Change of scenery

Just thought I'd mention here that I have left TransCore, and have 
accepted a position with American Messaging paging. I will be 
responsible for maintaining infrastructure across NE Ohio, most of W. 
Virginia, and extreme eastern PA.

Our local NBC affiliate KUSA-9 has one of these continuous "Weather  
Plus" channels already going as does the local ABC affiliate KMGH-7.   
They're a mixture of a continuously updated weather info set into side  
and bottom bars, and a running loop of pre-recorded local news and  
weather forecasts, along with additional commercials (of course).

http://www.9news.com/life/programming/default.aspx - KUSA DT and KUSA  
DT2 listings.  As you can see, KUSA DT2 is in "perma-Weather" mode  
right now.
Same thing with KMGH.   http://www.thedenverchannel.com

The only really useful part of that is if you don't have Internet  
access, you can see the live radar loops anytime.  I guess it's also  
more interesting to watch local news loops than the same four stories  
from CNN over and over with talking heads, sometimes.

I'm not sure what the CBS affiliate KCNC-4 is planning for their sub- 
channel(s), but I don't see anything on their website about it.  Their  
transmitter supervisor is a Ham, and a "good guy", I should ask him  
sometime when it's convenient.

Also, NTIA is issuing $40 coupons toward converter boxes for SD TVs:  
https://www.dtv2009.gov/ 
   -- if you "qualify".  I assume this means you have to say you don't  
have any pay TV services.

Around here, it literally took an act of Congress to get our DTV tower  
up on the same mountain that TV has broadcast from since the 50's.

http://www.hdtvcolorado.com/

There's a NIMBY group still fighting the Constitutionality of that  
particular maneuver, but the tower and shared 20,000 sq. ft. building  
for ABC, NBC, and CBS and what used to be UPN (I don't know what they  
are now, they're called "My 20" now...) is already under construction  
on the mountain, and once the DTV tower is up, 4 other smaller towers  
are coming down as part of the deal.

Here's the NIMBY group's website, for a good laugh.  Especially  
anything to do with RF engineering -- they're utterly clueless.   
http://www.c-a-r-e.org/ 
   It's totally out of control, and has been for years.  Making a few  
lawyers a lot of money, though.  That's always a given, nowadays.

Fox-31 KDVR and the TBS affiliate KWGN-2 put gear on other towers  
elsewhere.  ABC, NBC, CBS, and UPN have all been broadcasting their  
DTV signals at extremely reduced power levels from a Downtown  
building, which gives all of them pretty wimpy coverage into the  
suburbs and the rest of the Front Range corridor.

All are being sued in one form or another by the NIMBY group.

The City of Golden, CO has been involved on and off in the fight over  
the tower.  The Coors family (Coors Brewery is in Golden, CO) either  
really agrees that they don't want the tower, or there was pressure to  
support the city or face zoning problems later when/if the brewery  
needed to expand.

The Congressional law tactic sure got them out of the fire, if there  
was behind the scenes pressure,  and we're all glad Pete Coors didn't  
win his Senate bid if he really didn't want a sane single super-tower  
on the same mountain TV's always been on around here.

Some early proposals had the broadcasters moving to sites that were  
traditionally only 2-way sites, and repeaters and other users on those  
sites would have had an RF ultra-mess to deal with... broadcast being  
"segregated" from 2-way, most of the RF engineers around here that  
I've talked to seem to think it'd be a good idea to keep it that way.   
A rare treat.

My guess would be that the additional "channels" aren't all that  
useful yet to the broadcasters, until the change-over happens and the  
majority of folks are receiving all of the channels.

I doubt the additional channels will be carried by the dish folks due  
to bandwidth limitations, but local cable companies seem to be  
carrying at least a few of these sub-channels from the locals.  It'll  
be interesting if they ever find anything more useful than continuous  
weather/news/commercials to put on them.

So far, I like NBC's 1080i standard better than the 720p standard most  
of the others are going with, whether or not I can "really" see it on  
my medium-sized LCD panel

So _you're_ the one!  That listing generated some discussion in our

I think there is still a Johnstone Peak machine, but I've forgotten
what freq it's on.  I bet Mike remembers the old call sign.
