Anyone able to pick up EV 91 in Seattle?

I'm having problems finding it. I've got about 70-75 reception on 82 and have tried switching around the coax and LNBs (confirming that they're ok) but I only ever get 82, and zip for 91...

I've tried flipping through transponders, but I only get "not locked" or "wrong dish (82)" when I'm hunting for 91.

AZ: 135
EL: 25
Skew: 65

Any suggestions? I'll try playing around with the skew a bit more, but it seems like I must be close since I'm picking up 82 without any problems ??

Great, I have 250 channels available to me, but because of what you said I'll be hooking my camcorder up to my TV tonight to brush my teeth. :D

Hey Ken -
Maybe we should set up the Teeth 'n Comb channel.
Wonder which provider will beat a path to our door to get the rights?
(have you seen some of the home 'n car shows they have on, now?) :)


Looking forward to your report tomorrow. Inquiring minds want to know.

Thanks Everyone!!!

The tree was in fact blocking 91. I thought I was hitting 82 to the right of it, but with the skew it was actually well to the left of it.

I moved the dish to the other side of the house and had no problem finding the two...

You can get 91 in Seatlle...its too close to Vancouver (BC) to not :)

how close....9 degrees off :)

make sure you are using the left (if you have 2) LNB...thats 91

numbers I show are
25.3 elevation
135.7 azimuth
skew of 62

but you have to take in magnetic deviation, which is like +10 so its 145 azimuth

Iceberg,

I'm confused as to how you are applying the magnetic deviation to the true azimuth for Seattle. I thought the magnetic deviation for Seattle was ~ -19 to -22, depending upon the resource, and this negative value would be added to the true azimuth

135.7 + (-22)=113.7

Although this does seem to be more east than I would have guessed. Enlighten me oh great one! (Before I set-up my first dish)

Anole
just checking...

Google search on: "Seattle Longitude"....
Latitude: 47° 39' North Longitude: 122° 17' West
using: 47.65 and -122.28

Antenna alignment tool with magnetic deviation built in:
http://www.satsig.net/ssazelm.htm

bird @ -82
(az) = 131.09
mAz = 112.05 *
elev = 22.96
skew= -30.51

bird @ -91
(az) = 140.58
mAz = 121.54 *
elev = 27.47
skew= -25.33


* corrected for local magnetic deviation.

HOWEVER, these calculators are not nearly accurate to two digits to the right of the decimall place.
Get a sat meter and a compass, aim as best you can (if you're within two degrees you are doing good), and tune for maximum smoke.

edit: wow, the above numbers are way off from where you are looking!
maybe these are wrong.
never trust just one calculator.
find the bird and tell us where it really is. ;)

No problem here (in central Europe) with a 10-footer. Do note that 9.4 dB required for the lock.
The mod is DVB-S2 8PSK with FEC 5/6.

Hard to believe that the guy who runs this site, whos main focus is communications, and a guy who lives less than a half mile from the ARRL and W1AW does not have his ham license!

Well I want to change that in 2024!

Our local police department is moving to our states digital system next month and I have been working with our police department to get ready for the move, as I am the one who streams their radios online to Broadcastify. They put up a test feed for me and I was having trouble picking it up in the house, so last week as a christmas gift for me I put up a brand new Diamond D3000N Antenna on the roof. The Antenna is 40 feet in the air, on top of that our house is on top of a hill. :)

With that new antenna I am now picking up the. new digital system... and since I got the new antenna... which can also transmit at up to 200 watts... this may be the time to get into ham radio. :)

So how do I get started? What advice can people give? What kind of euipment should I be saving up for?

Without Morse Code, I should be able to pass the test without an issues.

So where do I go from here?

What would be a ballpark cost of getting into HAM radios? This would be for the equipment, antennas, etc.
To address the op's question, the true answer is literally almost anything you want to spend. Both at the bottom and top ends of that scale. If you don't have the big bucks to spend (...who does?), you can forget about steel towers and install homemade wire antennas like dipoles, inverted vees, verticals, loops, EFHW, etc. You can get good performance from these and costs remain affordable for most.

For a radio, buy used from a local club member. You'll learn about your club and develop useful, educational and fun relationships too. Or, if you can afford new, then buy from an authorized reputable dealer. When learning, if affordable, I'm actually a fan of new since you already have lots of hurdles to be challenged by. Having a radio that operates as it should with a new warranty with the latest technology can smooth your learning curve and give better results.

I understand your feeling regarding the term ham but I use it if I say amateur radio but I can tell people aren't getting what I'm talking about. Almost everybody has heard of the term ham when talking about radio ops. Sometimes people think amateur refers to somebody who doesn't know what they are doing. It's amateur, as opposed to professional as in earning money.

Also it's ham, not HAM or Ham. It's not an acronym nor a proper noun.

My local time is fine. But for a week or so I've been sometimes seeing, in the forum list, things listed as the latest post that are not in fact the latest post. For example, the FTA forum is showing Cyberham's message in Moved News Feed as the latest post right now. There are newer posts.

Then just a little while ago, I got a notification that someone replied to a post I made. When I clicked on the notification bell in the header bar, it showed the time of the reply as "Tomorrow, 7:50 PM"!

Something is not right somewhere, but I have no idea what or where.

AT&T runs First Net which was set up so first responders have a signal almost everywhere, which is the case around here and up and down the east coast when I've been traveling. In my experience T-Mobile has the fastest network but patchy coverage while Verizon has a slow network and also patchy coverage as well. We also have a iPhone on T-Mobile and one on Mobile-X which uses the Verizon network, so comparison is easy.

We also have a iPhone on T-Mobile and one on Mobile-X which uses the Verizon network, so comparison is easy.
I did a 2500 mile round trip road trip a few weeks ago, there were a handful of places where Verizon had service and I had nothing on FirstNet. Most notably in the backwoods of Kentucky and Tennessee. Those same places I had no service on T-Mobile either. In populated areas, like the Lexington metro and Knoxville metro AT&T not only had great coverage, better than Verizon and T-Mobile generally, they have n77 everywhere. I hit 1.2 Gbps or higher pretty much everywhere, beating out the other two. That is the exact opposite here back in Western NY. Very little n77 on AT&T here and T-Mobile always rockets to 1.5 Gbps or higher.

As far as I know, there is no AT&T tower in my town. The tower I connect to when I'm outside, no service indoors, is one about 4.5 miles north of me in a different town, I can barley latch on to band 12, not 14. It's LTE only but when near that tower I exceed 200 Mbps which is phenomenal for low band LTE, but T-Mobile and Verizon have mid band on the same tower, and i'm well over a gig.

I'm looking forward to the n14 conversion and deployment of n79/4.9 GHz. Since AT&T can't sell their home internet service in NY State, I don't expect big things from them besides the enhancements to FirstNet.

We're in NY and we can now. We're an AT&T retailer and have been selling AT&T Internet Air for a few months. It's $35 a month if you're an AT&T post paid subscriber, $55 a month if you're not a subscriber.

The AT&T Internet that everyone has access to is AT&T WorldNet aka att.com which is the same backbone created in 1994 that is a joke. AT&T has 3 Internet tier 1 backbones. AT&T Global Network Services formerly IBM Global Network Services (prserv.net) and AT&T Emerging Network Services, formerly (CERFNet (California Educational and Research Foundation Network) that was part of NSFNet (National Science Foundation Network). AT&T WorldNet has always been a inferior and not the same quality as the other two which are highly respected.

No, Fiber to the towers is not CenturyLink for Drexel, MO because it can be either ILEC (Incumbent Local Exchange Carrier) or it can be CLEC (Competitive Local Exchange Carrier).
CenturyLink which has been known as Lumen Technologies is not the incumbent carrier in Drexel. In the Drexel, Missouri wire center and surrounding Cass/Bates county lines, alternative fiber and Competitive Local Exchange Carriers (CLECs) with active transport infrastructure include:
  • Peoples Telecommunications (Peoples Services): Operates extensive localized fiber facilities directly in the Drexel and Louisburg area, functioning as the primary regional CLEC/independent carrier on the ground.
  • MoKan Communications (MoKan Dial): Maintains contiguous fiber routes right along the Missouri–Kansas border surrounding Drexel, often interconnecting or leasing dark fiber to neighboring towers.
  • Conexon Connect: Builds and operates middle-mile and last-mile fiber networks across Cass County in partnership with local electric cooperatives, providing modern fiber transport paths through rural pockets around Drexel.
  • Craw-Kan Telephone Cooperative: Holds an adjacent fiber footprint on the southern/Kansas edge of the Drexel exchange area that supports regional carrier transport.
(Note: While Consolidated Communications—which operates retail services under the Fidium brand—is the historical wireline incumbent in Drexel itself rather than CenturyLink, wireless carriers frequently bypass the ILEC copper plant by pulling backhaul from Peoples or Conexon's fiber rings.)

So when it comes to connecting to the internet, you are really dealing with up to 3 companies whether it's AT&T or Verizon.

With AT&T, it can be up to 3 companies.

The first company is AT&T Wireless or AT&T California (ILEC) which provides the wireless connection or wired circuit to you.
The second company which applies only to physical circuits and not wireless service is AT&T Advanced Solutions Inc better known as ASI as a CLEC who provides the data transport between you and the ISP. If this was wireless, then it would be second company being the ISP. AT&T WorldNet being the ISP.
The third company would be the ISP itself which would be AT&T WorldNet if this was a wired connection.

As far as the Verizon backbone is concerned which is what was known as UUNet aka AlterNet (AS 701) as BBNPlanet (AS 1) later known as GTE Internetworking/Genuity has been sold to Level 3 and then CenturyLink which rebranded to Lumen Technologies.

While it will connect to Verizon's backbone which highly depends on the Access Point Name (APN) as using San Francisco where I am located for example,
a direct Verizon mobile customer will connect to Verizon's backbone in San Francisco. A Comcast/XfinityMobile customer which uses Verizon's towers will not as the first hop as seen in traceroutes can be in Houston, Chicago or Atlanta so to reach someone who uses Verizon across the street, the data packet will travel to one of those first and then travel back to San Francisco using Verizon. In both cases, you will always see Verizon Wireless as the first few hops before it will reach Verizon's Internet Backbone. MVNOs do not use the default APN and usually has their own gateways which in the case for Xfinity Mobile is COMCAST.RSLR.VZWENTP which is read just like internet domain names, in reverse order, Verizon Enterprise-Reseller-Comcast. XfinityMobile originally had high latency because of this reason which I and many others complained about but XfinityMobile ignored the issue until I filed a complaint with the FCC that finally pushed it to Xfinity Mobile's Engineering department which finally made it connect to Verizon Wireless's IP network in San Francisco and connected to Verizon's backbone locally.

So basically the APN is the invisible network you will not see in the traceroutes due to:

Mobile Access Point Names (APNs) – Cellular Networks

A cellular APN (the gateway connecting a mobile device to the carrier's packet data network):
• Carrier-Grade NAT (CGNAT) and Tunneling: Cellular data traffic is typically encapsulated inside tunnels (such as GTP - GPRS Tunneling Protocol) and routed through massive carrier gateways.
• ICMP Filtering and Rate Limiting: Mobile carriers and core network routers frequently block, drop, or rate-limit ICMP/traceroute responses (TTL Expired messages) for security, privacy, and to reduce router processing overhead.
• Hidden Hops: Carrier-grade firewalls and internal routers may be configured not to reply to probes or decrement TTL in ways that expose their internal architecture.

The backbone one connects to is only one part of the equation as it depends a lot on what sites one frequently connects to and what backbones those destinations are connected with that determines the quickest path between the source and the destination. Some destination sites only are connected to one backbone and some are connected to multiple backbones for redundancy. That is why it matters to choose the ISP that works the best for the sites one connects to if you want the best performance possible as the lowest latency and the speed is the objective of reaching the sites you most frequent. While there are many tier 1 backbones, the ones that carry 90% of the traffic worldwide are the ones that hopefully whatever ISP one chooses is directly connected to. There are also private peering points and public peering points locally so it does not always have to travel to a backbone provided that there is a peering agreement between the networks. All of this is done using BGP4 (Border Gateway Protocol version 4) which is how routes are announced as the path is determined by ASN (Autonomous System Numbers) so the routing table for different IPv4 or IPv6 can route a different way which all depends on the BGP4 announcements that the destination networks announced so like some sites may be just AS 701 100% of the way while other sites may be AS 701 to AS 1 or more and if there is peering, it may not even touch AS 701 at all and just connect directly between ones own AS drectly the the others AS (Autonomous System). AS has nothing to do with physical distance but just the shortest path of getting there.

This is better explained here:

As I own and run a ISP, a lot of sites are actually local on the network as it's all on Akamai Technologies CDN (Content Delivery Network) servers which are physically hosted at our location so if one was visiting Apple, Microsoft, etc, the content is already on the Akamai server so it usually does not even need to travel the entire internet to get to it.

But on my home connection which is Comcast, it does travel all the way on Comcast before it hands off to Akamai's network in San Jose, CA before it reaches the Akamai server in Los Angeles which is probably located at One Wilshire Blvd in LA.

All of this is done using BGP4 (Border Gateway Protocol version 4) which is how routes are announced as the path is determined by ASN (Autonomous System Numbers) so the routing table for different IPv4 or IPv6 can route a different way which all depends on the BGP4 announcements that the destination networks announced so like some sites may be just AS 701 100% of the way while other sites may be AS 701 to AS 1 or more and if there is peering, it may not even touch AS 701 at all and just connect directly between ones own AS drectly the the others AS (Autonomous System). AS has nothing to do with physical distance but just the shortest path of getting there.

This is better explained here:

As I own and run a ISP, a lot of sites are actually local on the network as it's all on Akamai Technologies CDN (Content Delivery Network) servers which are physically hosted at our location so if one was visiting Apple, Microsoft, etc, the content is already on the Akamai server so it usually does not even need to travel the entire internet to get to it.

But on my home connection which is Comcast, it does travel all the way on Comcast before it hands off to Akamai's network in San Jose, CA before it reaches the Akamai server in Los Angeles which is probably located at One Wilshire Blvd in LA.

Yet to reach Charles Schwab compared to Apple, it will actually use a Akamai server locally in the Silicon Valley on Akamai's network.

The *'s just means that ICMP ping packets are blocked or ignored as long as the latency looks normal. If it's some high number, then it means there is packet loss.

Sorry, I meant Consolidated. That's who provided my DSL when I lived there and the tech who installed it told me they provide the backhaul to that tower. People's has only been in town for two years, maybe less.

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....
