Little problem my neighbor has.the.dish and weather I run 1000 watts or 5 watts the result is the same. I knock out the HD when I key up.says searching for signal. Tried every radio same result from stock 142gtl to my Kenwood 570d on 5 watts any idea what to do. The lady called the.dish company and they said there.was.nothing they could do because they run on the same frequency. Any suggestions would be.appreciated. |

This could be for a couple of reasons. 1) there is a brerak in teh sheilding capability of the coax they are using from diosh to the receiver. 2) Poor design of receiver, are the two mostly causes if it does it no matter what you run.
If you are sure your station is clean, it may pay to contact FCC and report it.
As an sided, I cannot see a satellite company running on 27Mhz - the dish needed would be astronomical, not the 18 to 24" they are. From the receiver to the tv (if using coax) it is usually around Ch3 (above 50MHz). A Google search produced the information that Dish and Direct both use between 12.2GHz and 12.&Ghz.

J didn't think so either bit the problem happen after they got a new HD receiver. I use to run my 2995dx with a.straight 4 pill and bother no one then even a stock 4 watt radio did the same damage. I run that coax copper sells with the solid center strand with no problems till now. The neighbor is also a.former ham operator who seems to make no effort to fix problem only to pick up the phone and make a call that he is watching tv. Trying to be nice and.work out the problem but soon I am just going to hammer down. Thank you. |

I see two potential problems, and one obvious one.
First potential problem is a bad connection of the coax cable to a connector either at the dish or the receiver. Second possible problem is the cable is exactly the 'right' length, and the HD sat receiver is lit up with RF by the path.
Possible solutions:
1. Ground the HD receiver to all other components, and then to ground rod just outside the installation location.
2. Run a new cable from the dish to the HD receiver.
3. Stop using a linear amplifier on the CB band.
Regarding #3, assuming you were not breaking any FCC rules, you yourself could call the FCC and tell them what is happening. You'd be surprised how fast a cable or satellite company will fix something when they get a phone call from the local FCC field office.
And, since you mentioned that the owner of the HD satellite receiver with the problem is a former ham op, they would certainly understand the problem isn't on your end if you had a completely legal station.

We just had a class at the ham club where ferrite chokes were discussed in detail. instructor says put them on every wire, closest to the source, on both ends. Claims this it the way to go, put them on the coax from the dish to the receiver, the HDMI cable and the power cable, even put 2 or three, more is better. I am no expert but the class was informative. |

I see a couple more places you might look to help with the problem.
1. Take the 1KW amp out of line bag it, rap it and put it and your exports in the attic.
2. Make sure the 142 is at 100% modulation and 3-4 watts. (Legal)Before calling FCC!
3. You made no mention whether or not you have a Low-Pass filter in line. If you don't, Copper has a good one, DF 3000 pt#PO3-00003, rated at 3KW, best $29.99 + tax and shipping, good investment. Put it as close behind the transmiter as possible, always remember, nasty signal in, nasty signal out!
4. Don't get angry and just hammer down! If this guy is an old Ham, he knows how to stop your radio fun.
5. Check all your grounds at your station, inside and outside. Check ALL coax connections, make sure they are clean, tight and insulated. When metal is heated then cooled fast, it will change its size. If you've had the typical Northern winter and winds, something could be loose, broken or cracked !
Take the advise of 237 and 833, both work in what we dabble in. Check out what 392 offered. And look at your radio shack, make sure your house and feet are clean, before stepping into your neighbors'.

Thanks for the advise as far as the amp it is only used once in a blue moon for shooting skip not running it to talk to locals. I have.tried rf filters the chokes and.nothing works they have 4 tv's in the house the only one it messes up is the one with the HD receiver never had this problem till the old receiver broke and.they installed the new one. Like I have said I have not bothered any of my neighbors at all no matter what I run (not bad.for.living in the city) until now. They called the dish company and.they told.her that they use.the same.frequency for the HD. Did a test yesterday parked my mobile in front of my house and was.talking to some locals same problem. Knocking out the tv. I say the problem is on there end I'm sorry a 2970n2 and a k40 should not do that this is not the 70's where everyone had tv antennas and (language edited by Tech 833) telephones. I hope u understand my point. |

Did he change the HDMI lead when he replaced the receiver ? Could be that the HDMI lead supplied with the new receiver is of poor quality and picking up RF , just checked my own one and funnily enough it is 100" long very close to a quarter wave on 27mhz .

First of all, a 2970 is NOT a legal radio to use on the CB band.
The point we are trying to make is that the problem is obviously not on your end. Yet, you are guilty until proven innocent.
We're suggesting to you that you first make sure your setup (base and mobile) are perfectly legal. Then, we suggest you get the FCC involved to force the sat company to fix their problem.
This will save your radio hobby and the tranquility of the relationship between you and your neighbors.
You might want to take a look at FCC part 95 rules before you proceed.

I run a dipole that is V form. I have HD dish next to it and run 50 to 100 watts on HF and never had any problems. Sounds like you are splattering all over the place. |

Update. I called the dish company myself and told.them the problem. They said I shouldn't be interfereing with the dish. They told me to have the person call up and they would trouble shoot the problem. Have not heard back yet.now regarding the 2995dx I know its not a legal cb but is it a legal ham radio? I was told due to it being an export radio not suppose to use it I'm the ham bands. Going for my technicians license and just wkndering. Thank u |

You can indeed use a 2995DX in the ham bands after you have your ham license.
'Export' radio or not, that isn't the issue since there is no requirement to use type accepted radio on the amateur bands. In fact, you can legally use homebrew gear in the ham bands, so obviously, using a 2995 radio isn't a problem either.
There are limits in peak power output, occupied bandwidth, specific band plan assignments, etc.
Stay in band, and below the max power, and enjoy! If on CB, then you need to use a type accepted radio and no external RF amplifier. Then, the satellite company cannot accuse you of operating illegally.

Tech833 here another one for u if I'm running a Kenwood on the cb band with the legal wattage is that a violation or not. Also the dish company is coming out today to check the neighbors equipment. Keep u usages on how that goes. |

Yes, it is a violation.
Check FCC rules part 95, rule 9(a).
You are only allowed to use a type accepted radio on the CB band. The Kenwood is not type accepted for part 95 Citizen's Band use. It has nothing to do with the power output.

Well the dish guy didn't know his hind end from his elbow when it came to the dish interference. Checked there equiment and left. What a waste of time. Also I told them to try another receiver and see what happens and the lady didn't want to so she wouldn't loose her dvr shows. Yea. Kinda stuck between a rock and a hard place. |

Actually, you are NOT between a rock and a hard place.
If you go with all-legal part 95 CB equipment, you have the upper hand. YOU can call the FCC and get them to lean on the dish company.
The problem you face is in the U.S., local police have jurisdiction over you operating on CB (look up bill HR2346). Your neighbor could simply call local police, and they can come to your home and force you off the air. You could also be arrested. Don't scoff, it has happened.
Is it worth it? You may have forgotten how well a perfectly legal station can perform. You bet it would be worth it. Not only to ensure your continued operation, but also to keep the peace with your neighbor.

I wonder if the local or state police could still enforce the FEDERAL FCC law's since the Supreme Court had rule that local or state police could not enforce FEDERAL LAW'S for people here illegal. It would seem to me that this would be the same for radio's since Fcc is Federal LAW not STATE LAW. |

I understand what u are saying. The problem lies on the frequency we talk on. It is above 40 and that is already illegal. I have a bone stock cobra 142 but no extra channels. Which leaves no one to talk too. Don't know about where u guys are from but in MA not to many cbers left. Could hook up the president Washington but is converted and no good. Wattage is fine just the channels. Could I not just switch out the stuff before they come by (knowing they are coming).beleive me I just sold out all my amplifiers this past weekend just to prevent future problems. Not running anything out of this world. Thanks again |

Listen to TECH 833. He will alway's tell you right. Most likely a letter will come to you in the mail telling you to stop if you had any trouble. Last but not least they will give you a visit before you would even know it. Ground your antenna, your radio, to a ground rod and get a good tvi filter here at Copper. |

Look up HR 2346, CB. Local police DO have jurisdiction over CB interference. I certainly do not agree with it, but it is true. The FCC handed enforcement to local law enforcement.
The average police officer or sheriff deputy has no idea what a CB radio looks like, let alone how one works. All they know it a citizen is complaining that a CB is interfering with their TV reception, and it is up to the officer to do something about it.
CBers have been arrested (you don't want to know what that does to your insurance rates) and harassed by cops over CB interference complaints already. Do an internet search, PLEASE. Don't take my word for it.
I was just trying to save our friend Mass here some trouble.
But, it appears that my words are going unheeded, so I'll just take a stand by and watch the show now.

Tech 833, I agree with you as it is now and had been but, it had not been tested on this subject in court yet but, if it would go as the supreme court had rule on local police enforement of federal law on illegal's being here then the supreme court would most likely rule the same that local state law enforcement can not enforce federal law. I am not saying it can not be done or had not been done just that if tested by someone that this would be true for the Fcc as well. I think local law enforcement should be qualified before they do this.. |

i agree ive owned numerous splatter sticks grounded them ,still no good. i honestly
starting to believe its the high tech dvrs and hdtv .with cheaper/less filtering.to mass id ground it using a 9ft gounding rod and BRAIDED
flat copper stap.also what kinda coax ya using?
if using a solarcon id try the gpk may help /may not.then get a lowpass filter for your stock 142
and buy a high pass filter for your neighbors
that way you will be LEGAL.and it shows you made an honest attempt at tring to resolve the issue.
after all this and still dont help try talking
to your neighbor and arrange a time when shes not home and you can use radio that way..

If you have a radio that had the modulation open up and or a power mic and also to much power that is where the problem comes from. The antenna only will broadcast what the radio will put out like bad harmonic's. On the I max 2000 I had done as TECH 833 had said to do. Mount the antenna about 28 foot, bend the bracket of the GPK to about a 45 degree angle. Of course a ground is a good thing to do for many reason's. My ground is a piece of rg-8u cable with the center wire for the ground connection to the ground rod and the shield is left on the cable. I have my own reason for doing it this way. |

local law is not enforcing fedarel lw. The bill allows local governments to pass ordinaces requilring cb'ers to operate within FCC rules. they then enforce the local law. First they must enact the local law.

I called the fcc myself. The lady on the phone told me that its not my problem and they won't even investigate the problem. She stated its the dish companys problem to fix with filters. She stated that I have done.my part. Though I am not licensed I am following within the rules and regulations and I have the right to use my cb. By the way j have a imaxx2000 about 30 feet in the air(to the bottom of the antenna). |

Massappeal, Have you read the article for the GPK that TECH 833 had done where he spoke of bending the GPK bracket to where the angle of the bottom radial's would be at about a 45 degree angle? I have done mine like that. |

Isn't a gpk usually just to improve your receive. Correct me if I am wrong. The coax I run is the best stuff copper sells. It has the solid center strand 400 athetaol. U have to remember I never had this problem before until they switched to a HD receiver I don't bother there other televisions. I live in the city and no other neighbors have interference. I have asked and this was when I would run power to shoot skip. When 5 watts does the same as 1200 watts wether on ssb or am it must be a problem on there end. I cannot talk on my mobile in front of the house due to same result. |

Massappeal, If I were in your shoe's the first thing I would do is to check to make sure that I would only have no more than 80 to 100% modulation because more than that will give you splatter and bad harmonic's and that will cause some of your problem. Then I would make sure that my antenna is grounded. Then I would install a tvi filter that Copper sell's. Most of all I would read every article Tech 833 and other's had written on the I-Max 200 and the GPK. and the article's on how to properly ground your antenna and radio. A tvi filter will not solve all your problem's but it will help. I am no expert but I hope this will help you. Perhaps Tech 833 could add to this or correct me if I have given any wrong advice. HOW ABOUT IT 833. WE NEED SOME HELP AGAIN. |
