Topband: Radio World; Noise Floor; Where do we go from here?
Hi - In reference to ===> Today's Topics: 1. Re: Radio World; Noise Floor; Where do we go from here? (Guy Olinger K2AV) Check out the QST *readers comments* of March 2010 p55. Folks will have to be willing to pay a few $1 more for electronic items to be designed correctly to turn this problem around. Back in the days I worked for HP. we busted our butts knocking-down every significant 'birdie' radiated by a product in development. The NAB is highly concerned about the noise issue too. 73 Dick/w7wkr CN97uj _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: Radio World; Noise Floor; Where do we go from here?
These days, AT seems to have about a dozen suppliers. I'm not too sure they even have a current contract with 2-Wire. Six years ago they had not gotten a spec yet that they could farm out. They were clearly still in discovery mode. My neighbor's 3801 went toast not too long ago, and it was not replaced by a 2-Wire unit. My 3801 is still with us. His new unit is *also* NOT bothered by 160 QRO. I read the URL. The actual problem is hardly discovered in that situation. It's kind of like blaming a leak in the pipes on the well pump. The leak does stop when you turn off the pump, right? So therefore it's the pump's fault? Turning off the gateway can stop a lot of electronic activity all around the house. Including a lot of programming in the set-top boxes. Careful, careful. Chasing noise is demonic. 73, Guy K2AV.

No clue as to how many have been deprecated. Nobody on my block has one anymore. Read on. They have gone to a practice of using coax from the interface where the cable comes up from underground to the gateway box. Twisted pair is no longer used for that.

AT has a group, headquartered in New Jersey that is a national group specifically formed to deal with ham radio issues with Uverse. It's director is a well-known east coast ham, and they have the authority to force local repair groups to follow certain procedures in ham-related cases, and mark certain customers for automatic referral to their group. Anyone who has a current problem of this sort, should get in touch with the ARRL RFI task force, who will do an entry level triage to eliminate common issues, and then give cases that pass triage to the AT group I am talking about.

There are numerous reports on the web from hams experiencing RFI from and to Uverse. My main point is AT was complaining about receiving RFI, without keeping their own house clean. 73, Art NK8X On Fri, Dec 16, 2016 at 2:05 PM, Guy Olinger K2AVwrote: > Hi Art, > > I have uVerse, as do a lot of neighbors around here, and a huge > development on the other side of US64 from me is mostly uVerse, > > Of all the noises I have chased around here, uVerse has only been > responsible for very weak continuous tones, and those seem to have > gradually disappeared since they quit installing 2Wire 3800 gateway boxes > in favor of newer technology.

Re: Topband: Radio World; Noise Floor; Where do we go from here?
It is ironic to see AT's filings, since their uVerse product is responsible for quite an increase in the noise floor on HF.

Topband: Radio World; Noise Floor; Where do we go from here?
Greetings topbanders. . .we’ve had discussions before on the ever increasing noise floor. Looks like we’re not the only ones paying attention. I live in the country well outside the Des Moines area. In the past five years or so my noise floor has gone from –125 or –130 dbm to about –100 db (or worse) as measured at daytime on my quarter wave vertical with a bandwidth setting of 0.4 KHz. It appears to be due to construction of a few new houses even though they are 0.5 mile or more away.
