Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Geert Jan de Groot]

I do apologize for contributing to this off-topic thread...

A technical issue for cable modems is the uplink.
For downlink, the cable modem system uses one or more "TV channels to 
sends its data on. There is encoding and all that but the signal isn't 
un-like a TV channel.


The uplink is where the problem lies.

Cable modems typically use low frequencies (up to 50 MHz or so) to 
transmit their packets from the enduser modem to the headend. You'd need 
a channel bandwith of 8 MHz or so. Where does a cable operator find a 
clean 8MHz channel under 50 MHz?


Keep in mind that the ingress signal (from the enduser to the headend) 
collects all the RF leakages from the environment. All poor cabling 
together creates a massive reception antenna. And a single strong 
carrier in the channel may block it.
I had a chance to see the upstream spectrum ("ingress signals") and it 
was not a pretty sight.
I know that one local cable operator had to change channels because in 
the evening, strong shortwave broadcast signals leaking in were blocking 
the ingress channel of the cable-TV modems.


For this reason, the ingress system, in the DOCSYS system I looked at, 
was using direct-sequence spread spectrum (DSSS) to "smear" these 
carriers over the spectrum and reduce their impact.


Now, consider very strong carriers on the ingress. Carriers so strong 
that the conversion gain of the DSSS system doesn't help enough. In that 
case, the ingress channel is still fully blocked despite the DSSS measures.


What impact things a lot, of course, is leakly cabling. And from what I 
hear, American cable-TV systems have lots of leakage issues (here in 
PA0, cable systems are underground and are shielded very, very well; any 
leakage here is typically poor enduser cabling).


While the response of the tech is very wrong, perhaps the above explains 
a bit what is happening and the reason for his reaction. If it were me, 
I would see if things can be solved along these lines, considering that 
from what I read in QST, many USA cable-TV systems have a massive, 
massive leaking problem.


In the Netherlands, more and more spectrum is being moved from 
"broadcast TV" / cable-TV to mobile services. Cable-TV signals are now 
on frequencies that are also used by mobile phone users, with 
transmitters (handies) on short distance and hence strong signals.
Suddenly the jammers are not us pesky hamradio guys, but every person 
carrying a mobile phone. And the community now understands that the 
proper fix for this is not banishing the mobiles, but better cabling.
For cable-TV, there are now "kabelkeur" (www.kabelkeur.nl) qualified 
cables that have double shielding, and, more important, good connectors, 
connectors that frankly put the typical hamradio RF connector to shame.


And I wonder how this compares to the situation of the topic starter.
With emotions running high we won't get anywhere, but I hope the local 
ARRL community can step in, find out if my hypothesis is the root issue 
and work from there, considering that proper shielding is a CATV 
operator issue and no-one else's.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[jerry]

Shortly after I got on the air with my brand new Galaxy GT-550 (550
watt sweep tube finals), he called one evening to tell me I was
"coming through his wife's organ."

Imagine my dismay ...


I seem to remember that the GT-550 was plagued by spurious...  Don't 
remember if it

was harmonics or parasitics or mixing products.

All well and good in an ideal situation, but knowing the area that Eric

is popularly called "bandwidth") from Comcast and/or Verizon "behind the

Up here (suburban Portland) I did lots of research on features, service 
and reliability before settling on the Comcast bundle of internet, voice 
phone, and Xfinity cable.  Living in an already-wired apartment I didn't 
have much of a choice.  I was fortunate enough to talk the management 
into letting me put up my VHF/UHF j-poles - I didn't want to press my 
luck by having more wire/cable run in.


 I had (where did I put it?) the direct phone number of the regional

problem was resolved locally to my satisfaction the first time without 
"sturm und drang".


In sum - you get what you pay for.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Tom Azlin W7SUA]

In my case my DX-20 had not yet been on the air when the neighbor across 
the street complained about me wiping out his stereo system just after 
my Dad helped me put up a 40m vertical up on the roof.  After the 
neighbor found out I did not even have my transmitter he stopped 
complaining. Word got out ( my Dad?) and no one in the neighborhood ever 
complained again.

My speeds are nowhere near that in the Santa Cruz Mountains, but 
certainly more than good enough -- typically 85 MBPS down. The problem 
with their "service" is the lack of adequate backup for the loss of PG 
power at their fiber repeaters. 6 hours is the best they can fit in the 
enclosures, and before our massive wildfire last summer, battery 
capacity had deteriorated to 5 minutes. It's not uncommon for storms and 
failures in the PG system to last 2-4 days. With no cell coverage 
under normal conditions. when PG drops, we're out of biz.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Lyn Norstad]

We had satellite several years ago, and had frequent outages - especially in 
the Spring - due to severe weather, sometimes far away, but in line with the 
satellites.  We first switched to AT DSL and it was OK 15 years ago.  

Eventually we went with Comcast/Xfinity cable, and have had virtually non-stop 
service for at least 10 - 12 years.  They own the cable biz in Chicagoland, and 
outages are at a fraction of 1%.  Most notably occurring only when they have 
upgraded service (like installing fiber).

I currently have 235 Mbps down, and about 20 up for ~$80/mo.

We get the bulk of our TV OTA (85 broadcast stations) plus occasional streaming 
... but our main cable use is Internet.

Hi Eric,

I see that you're in Santa Clara, so likely have many options for 
alternate carriers.

Street View shows pretty much unobstructed view of the sky which makes 
you a great candidate for Starlink. W6GJB and I have both signed up for 
it, and are six months into waiting. Neither of us has cell coverage. 
Comcast and satellite are my only options, Glen has flaky DSL from AT, 
and satellite. He's tried two, latency makes them slow and prone to 
dropouts. He has a good enough view of the sky that Starlink needs; mine 
is pretty limited by the tall redwoods, but I'm hoping.

[Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Ron Bell via Elecraft]

Unless you have no alternatives, find another ISP.  Comcast is not a great
or consumer focused company.  If you have a lot of time and energy, you can
fight this and may win.  If you dont have Verizon or an alternative wireline
company in your area, look into Starlink, still in Beta but I am hearing
great reviews from those who have it.

Hi Eric,Xfinity is a closed system.? If your amateur radio operations are
causing problems it is their problem to fix.That said, a non ham friend back
in WI has been having recurring outages on his Spectrum system.? Technicians
have been out to his house several times and they acknowledge that there is
a problem in his subdivision.? Spectrum has documentation of the outages.The
last visit by Spectrum the technician said that the problem was probably
caused by a ham in the neighborhood.? ?As far as I know there are no hams
near him.? The problem is that Spectrum doesn?t want to spend the time or
the resources to fix the problem. It's just easier to blame the neighborhood
ham.I explained this to my friend and
  he recently was told that Spectrum was going to replace the trunk lines
and distribution amps in the subdivision.? No committment on a date
yet.73,Gary K9GS Original message From: eric norris via

XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS Dear Gang:Xfinity, our
internet provider, showed up at 7:30am this morning, to explain to the XYL
that we were being cut off for good because my amateur radio activities had
caused wide area outages.? Oddly, these wide area outages did not include my
own house.? They told her the antennas themselves--absent any power--were
the problemThe last time I was threatened, I installed chokes and
opto-isolaters on our shielded ethernet lines, and after being told they use
14Mhz as their carrier frequency, I have stayed off 20m, only using 100w
unless I'm in a rare contest.? I asked  to speak to a technical guy--they
gave me a number which I called, but he never called back.Any Ideas?? Does
anyone have a contact at the ARRL, or know a communications lawyer

[Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Dana]

Questions:

1. is this coax?
2. do you use a cable modem?

I found on 160 m my cable modem kept resetting…
discovered the upstream side uses HF and above 30 Mhz!!!
Fix?  
Grounded the cable to my system ground (the existing cable ground was a joke) 
…put some ferrites on the cable near the modem.
as a precaution put the modem in a copper screened box for testing…
Reset cured -  … with proper grounding and ferrites….

You are Federally regulated, and so is the Cable company… so any issues are 
likely their plant or
the gear attached to their plant…..(ie cable modems with improper bypassing or 
disconnecte drop lines etc...

The towers stay, send that reigstered letter and CC ARRL….

A T-mobile hotspot is probably easiest. With 5G, I have measured speeds up to 
700 megabits and typically around 300 megabits with the occasional dip to 100 
megabits. $50 per month.

One more comment - be aware that the "technicians" that you see driving 
around in those white "Xfinity" trucks are not Comcast employees - they 
are "job shop" contractors who have no authority to speak for the 
company on policy matters.  Did they really shut your service off?  Read 
your contract - you my have arbitration rights before a shut-off.

My girlfriend has a setup like this in rural NH. Cricket Wireless will sell
you a whopping 100 GB data on AT's network for just $55 a month. We get
about 15 Mbps down and 5 Mbps up with 50ms latency (to speedtest.net's
servers), although of course that will vary based on AT's local network.

She's got a fancy industrial/weatherproof modem; I can find out the model
if you're interested.

There may be more options than you realize that avoid having to deal 
with the cable company and have no potential for interference to/from 
the amateur station.


I recently bought a house here (near St. George Utah).  There is no 
cable in my neighborhood so at first it appeared that the only option 
was DSL (via the telephone line) at 3 Mbps for $50/month.


But a quick Internet search found three local companies that offer 
"Fixed Wireless" Internet service.  This is where they beam the Internet 
to you via microwave from stations on nearby mountains. Costs range from 
$40 to $200/month for 25 to 300 Mbps.


I had a similar setup back at my house in California that had no DSL or 
cable available in the neighborhood.  Once I got the antenna properly 
located it worked reliably and of course there was no QRM to/from the 
HF/2 meter ham gear.

Yeah...normally it takes a 4-hour series of phone calls, half of them
involving screaming invective, closing a bank account, and getting a credit
card replaced just to get RID of a Comcast/Xfinity account. I know, I had
to do it when we switched to Verizon FIOS the day it became available at
our location.

If you have any other option besides them, do yourself the favor of signing
up with that other option. Xfinity is horrible, and even though I had to
threaten lawsuits in perpetuity to get shut of them, they still send us
junk mail over a decade later.

Yeah, but they may only be satisfied if all the antennas are gone, and

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Drew AF2Z]

I would take the easiest way: tell them whatever BS they need to hear to 
be satisfied; then operate however you like without restriction. Dump 
Comcast at the soonest opportunity.


I would not waste my time with lawyers, letters, phone calls, 
explanations, etc. As Mark Twain said: Never argue with an idiot; they 
will drag you down to their level and beat you with experience. This is 
similar to dealing with corporate bureaucracy.

My bet is you have a rogue tech who couldn't find the problem and 
decided to blame you.  He greatly exceeded his authority and as soon as 
a higher-up hears what happened, this will be reversed.  Besides, since 
we know you aren't the problem, the problem is still there and his 
"solution" will be proven wrong.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Fred]

Circa 1958:  Neighbor and TV Repairman came to my parent's door ... 
"Your son's ham radio is interfering with my TV.  Dad: "Our son has been 
away at college for 2 years and his radio equipment is packed up in the 
closet."  Long pause ... then TV guy, "Well his wire antenna is still up 
there and it's between my customer and Mt. Wilson, and it's sucking all 
the signal out of the air."  Dad: "I'll ask him to take it down next 
time he comes home."  That didn't happen 'til maybe another year, I had 
a full time job at the local TV station at college and didn't get home 
very often.  I did finally take it down, neighbor's TV still didn't work 
well, and he still blamed me.

Eric,
I'm skeptical. Did you receive anything in writing or see a letter from Comcast 
stating this?
It sounds more like the Comcast tech taking it on himself to say you are being 
banned.
I would call their customer service and check the status of your account, get 
something in writing if it's true, then contact your state authority that 
regulates telecoms, and file a complaint.
I've never heard of anyone being banned as a customer by Comcast.

Anyone telling you the mere presence of an antenna is the source of problem
is someone who has absolutely no idea what they are talking about.

Ask them for a list of the dates, times, and durations of some of the area
wide outages and compare that information against your log book to see if
there is any correlation.

It is very likely there are other hams in your area. It could be someone
else causing the problem who may not be an Xfinity customer. If any ham
radio, or other radio transmissions, are causing their systems problems it
shows they haven't properly protected their equipment from stray RF and/or
they have a problem with an installation somewhere.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Michael Walker]

I guess hooking up the KPA500 right to your Xfinity Coax and doing
automated FT8 on 20M would not be the best thing to do.  :)

Sorry, I couldn't resist.

And, seriously, if it was me, I would head to the main local office if you
can. find the manager or owner and request him to show the data that proves
what is going on.  Don't be afraid to ask him if he is guessing or does he
have empirical evidence.  Take some technical help with you if you need it
and be professional.

I would also say, you have no proof as my internet works fine even when I
transmit.  Come over and watch for yourself.

Also, is the lack of internet affecting your health and safety?  Ask them
if they wish to take the liability for that.  Are there other ways you can
go on the offensive?

Best of luck, Mike va3mw

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[barry halterman]

This is rather interesting. Last year my local borough contacted me about
my antenna support. It is 30 feet high and is my end support for my EFHW. I
was asked when did I install the pipe? I said 15 years ago, why? I was
promptly told that the boroughs 1.2 GHz comm link between the pump house
and well head three miles up the road, was intermittent. I am in a valley
compared to the well head and their link receiver. In that past year the
electric company installed two tall towers for distribution lines a couple
hundred yards between the well head and my QTH.  I was the suspect, non the
less.
Turned out to be the antenna at the well head.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Wayne Burdick]

When I fired up my first transmitter as a novice (a DX-20!), little did I know 
it was leaking into a break in the coax cable in the attic. 

I found out two days later when a ham I'd never met copied my callsign off his 
TV. He looked me up in the callbook (I was a few blocks from his place), 
introduced himself, and helped me find and repair the cable. I ended up with a 
clean signal and a great Elmer.

But this is not the good ol' days, apparently.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[K4HYJ via Elecraft]

I had a ham friend who went through a similar situation with Charter - now 
Spectrum.  He called the state's public service commission to lodge a complaint 
against Charter.

Long story short, the public service commission sent a representative out in 
the field and they had the ham radio guy transmit while witnessing the 
"interference" in the neighborhood.  They saw issues but not at the same time 
the transmitter was operating.  Charter finally found 2 issues: a failing power 
supply on a network amp, and some terrible signal leakage on improperly 
terminated unused coax drops.

Charter took the easy way out and blamed the ham as a CB operator operating at 
illegal power levels.  Obviously they had no proof and ultimately had to fix 
their own problems.

Xfinity around here is all fiber based.

I'd also call the better business bureau!

Wow! Doesn't seem to make sense... so they believe that by shutting down your 
home internet that you will stop operating your station which allegedly is 
causing the interference? 

Or do they believe that by the sheer fact that Xfinity is connected to your

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Gwen Patton]

Sounds like the typical "I'm having trouble with X, and so-and-so has
antennas, so it must be those antennas making X fail. They have to get rid
of those antennas!"

I second that there's no way that the antennas by themselves, with no
signal being put through them, can somehow cause problems with a cable
internet system. It's also ludicrous that, to fix the problems with,
supposedly, antennas causing problems, they turn off the antenna owner's
*internet*, even though, according to them, their internet is not the
source of the problem.

I'd start doing some full power contesting until they come out and explain
why turning off your internet was a solution for antennas passively messing
with CABLE internet. The only thing that should interfere with CABLE
internet is a backhoe.

This reminds me of the Florida case where a ham was told to stay off the
air because a neighbor 3 doors down had problems with her insulin pump. So
once again, "see antennas, blame antennas" is the default. This isn't TVI
on VHF channel 2, guys. It doesn't work like that.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

Hi Eric,

There is a reason that Xfinity is the most hated corporation in America.

I had a similar problem with them.

What all the other commenters are telling you is true; legally you are 
in the right. However, good luck on making your legal rights stick.


Your only practical solution is to find another provider.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Jim Brown]

Hi Eric,

The problem is clearly in their system and/or customer-connected 
equipment. The most likely causes are 1) badly installed coax 
connectors; 2) customer-installed tap-offs; 3) Pin-One Problems in 
Comcast and/or customer-equipment; 4) modems and/or routers with poor RF 
rejection.


I suggest you do three things. 1) Find an alternate internet provider,

Anyone telling you the mere presence of an antenna is the source of problem 
is someone who has absolutely no idea what they are talking about.


Ask them for a list of the dates, times, and durations of some of the area 
wide outages and compare that information against your log book to see if 
there is any correlation.


It is very likely there are other hams in your area. It could be someone 
else causing the problem who may not be an Xfinity customer. If any ham 
radio, or other radio transmissions, are causing their systems problems it 
shows they haven't properly protected their equipment from stray RF and/or 
they have a problem with an installation somewhere.

Unbelievable 

Ignorance run a muck!

Be sure to keep us notified on your progress!

On a separate note, on People’s Court (TV show), two hams were fighting over a 
SteppIR that was sold at a flea market- long story but it came down to buyer 
beware and sold as is rule was the conclusion.

Maybe you could get another ISP?  ATT might serve your neighborhood.
Or Sonic.  I had Sonic for many years.  Their speed sucks, but they are

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[David Gilbert]

First off, there is no way that your antennas alone can passively trash 
Xfinity's internet network.  Whoever told you that is an idiot.


Secondly, you could offer to do some testing with Xfinity in attendance 
to verify whether or not your transmissions were causing a problem.  I 
have a small local wireless ISP that uses my tower to serve about 240 
subscribers in the valley below my QTH, and about a year ago he started 
to see what looked to him like random problems with the routers on the 
tower.  I suggested that we do some checks, and sure enough transmitting 
at high power on 10m caused his routers (one in particular) to burp.  I 
hadn't operated much on 10m previously because of the solar cycle.


He could stand there next to the tower and monitor the network with his 
cellphone.  If a small one-man ISP can do that, Xfinity can.  He checked 
his shielded CAT lines and all seemed to be solidly connected, so I 
suggested he was getting common mode interference on the shields and 
that he could put some clam shell ferrite cores (I suggested #31) on the 
lines near each box and antenna.  He bought a bunch of them and that 
solved the problem.


In my case, I have it written into our contract that my ham radio has 
priority over his gear, and I forced him to get my tower officially 
permitted for his commercial use of it, so the burden was on him anyway.

We just switched to getting internet through T-Mobile, a cell phone

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Mooneer Salem]

Yeah, I'm kinda surprised myself that they did anything on the ham bands at
all; I would have expected them to stay out of anything that could
interfere with us. For instance, I just logged into my Spectrum-provided
cable modem and the closest they seem to get to the ham bands around here
is 17.8MHz and 24.2MHz on the uplink. And considering where I live, I would
have expected my operation to have interfered with someone's internet
already if it was going to. (I do 100W *max* into a roof-mounted MFJ
magloop, but typically ~50W just to be safe.)

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Rich Lim via Elecraft]

Wow! Doesn't seem to make sense... so they believe that by shutting down your 
home internet that you will stop operating your station which allegedly is 
causing the interference? 

Or do they believe that by the sheer fact that Xfinity is connected to your 
home that your station is causing harmful interference which is being 
transmitted directly into your home box? 

I'm gonna follow this one closely.

Re: [Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[David Bunte]

Eric -

Xfinity is also my provider. I have never heard of such a thing... and I
had no idea they did anything down at 14 mHz.

I would call the ARRL directly and ask for suggestions on how to proceed. I
would also call Xfinity customer service and ask for justification. My
guess is that like most of us there is not a suitable competitor from whom
you can get service.

Best of luck de Dave - K9FN

Cameras?  Any ID card from him?
Intolerable from any company, let alone your provider.

[Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[eric norris via Elecraft]

Dear Gang:
Xfinity, our internet provider, showed up at 7:30am this morning, to explain to 
the XYL that we were being cut off for good because my amateur radio activities 
had caused wide area outages.  Oddly, these wide area outages did not include 
my own house.  They told her the antennas themselves--absent any power--were 
the problem
The last time I was threatened, I installed chokes and opto-isolaters on our 
shielded ethernet lines, and after being told they use 14Mhz as their carrier 
frequency, I have stayed off 20m, only using 100w unless I'm in a rare contest. 
 I asked to speak to a technical guy--they gave me a number which I called, but 
he never called back.
Any Ideas?  Does anyone have a contact at the ARRL, or know a communications 
lawyer?  Comcast/Xfinity will be back out here at 2pm Pacific time--I'd 
appreciate any help.  
My XYL depends on an internet connection to work.  Being off the air is 
unimaginable.
Frantic,

73, Eric WD6DBM
