Smith, I have DISH and the roof sat receiver sits literally 15-feet from the SteppIR DB-11. No evidence of RFI in sat reception. Even I was amazed. Doesn’t solve DSS/cable bundling, but that’s another discussion with my OTT hat on. Apple TV streaming with TWC as ISP, no RFI. But with the TWC cable modem into gigabit router I must take great care to use ample ferrites and even shielded CAT 6 cable. But I digress.

I switched from Comcast to Direct TV last November. I noticed NO RFI from the system, and NO interference to the TV reception. I was on at all hours, running 500 watts to a vertical.

Never had a problem with HF or 6M ops interfering with DirecTV.
Can't say I have noticed the DirecTV interfering with ham ops. When I first got DirecTV we had a problem when doing Pay Per View movies. We often lost the first few minutes of the movie. Finally figured out that when the kids would do popcorn in the microwave it caused the DirecTV to drop signal. Also noticed that we would lose WiFi connections when the microwave was operational. We got rid of that microwave. _________ 73, Jim - N4ST -----Original Message----- From: Elecraft [mailto:[hidden email]] On Behalf Of w9hak Sent: Tuesday, May 17, 2016 16:15 To: [hidden email] Subject: [Elecraft] RFI and Direct tv or Dish network I am contemplating dropping TWC and going to a satellite system.

I've had DirecTV in four different homes with two different receivers
for almost 20 years and never a bit of RFI has affected the receivers. I have gotten into the stereo amplifier on occasion but that is another matter entirely. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

In the '90s, had DirecTV for over 10 years with no RFI problems running full power. Changed over to Verizon Fios, etc. Now after 10 years of Verizon (now Frontier
 ) and ever increasing monthly bills, getting ready to go back to DirecTV!

Not that I'm a fan of Verizon the company, I'm not, but FIOS will rid you of all RFI blues.
My neighbors had Comcast and I would get the dreaded phone call time and again that I was messing up their TV. Thank goodness they are great people. Then they switched to FIOS and now I can contest to my heart's content running 1.5 kW with my 4 element SteppIR 100' above their TV room.

Had Dish-NET for several years and switched to Direct-TV two years
ago during a time there was contract dispute between Ch.13 (Anchorage) and Dish-NET that threatened that they would not carry the network programming. We are 65-90 miles from the TV stations which makes digital TV not watchable from off-air reception. No RFI either way from the mw satellite system but the new Direct-TV receiver switching PS gets into my 2m receiver. Fortunately, I am not using 2m when watching TV. We power-off the AC to the entertainment equipment when not using it (saves power consumption over time). I suppose some ferrites and shielding the separate switcher would solve this. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: [hidden email] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I have a DirecTV system and haven't had as good luck with RFI as the
others here. My dish is about 40 feet directly below and near the end of an OCF 80m Windom. It worked out that was the only realistic position that afforded full Sat views through the trees. Usually nothing happens at 100w HF output, but when I run the power up to 500w (depending on band), two of my DVRs either "turn off" (standby really) or start randomly recording whatever channel is being tuned at the time. I've got the dish grounded and the RG6 feed is passed multiple passes through large #31 ferrites, with no overall improvement in RFI. I would recommend much more separation of antennas and feedline than I have, if possible.

Some OCF dipoles work very well when used with a 2-choke balun, see DJ0IP for suitable designs. Spiderbeam make proper 2-choke baluns for their OCF dipoles but I don't know of any others. It's all about suppressing those common mode currents on the outside of the coax. He and I have both measured common mode currents with different chokes; see his site for details. http://www.dj0ip.de/balun-stuff/

I used to have “fiber to the home” while living in Bloomington, Indiana. The provider is Smithville Fiber and in general, their TV, Internet, Telephone bundle is excellent and price wise, very competitive. Having said that, their interface equipment (external fiberoptic to ethernet inside the home) is of such a poor quality that even while tuning the radio with less than 5 watts, the internet would freeze and cease to work. I tried to use multiple RF chokes on the coax from the antenna, the internal ethernet distribution inside the house, even shielding the outside interface box the best I could, but nothing worked. Other hams in the Bloomington area have the same experience and all of us traced it to the poor components and lack of shielding (contrary to FCC requirements) that they use in the provider’s installation. Obviously they never considered that ham radio operator exist and are protected under the FCC Rules. So we went as a group and met with their management. They promised to take action. I don’t know if they every did. Since then, I moved to North Carolina and am now using Time Warner Cable. I have a Hex Beam in my backyard using 100 watts. I also have a doublet fed with window line and a balun inside my attic, same power. No problems to report up to this date.
So, it is quite possible that the providers are using the least expensive equipment for cable, TV, and internet distribution. In my case back in Bloomington, Smithville had to change the cable box three times because of defects in materials and workmanship. I know that companies have to make money to subsist, but buying the lowest bidder sometimes brings its own problems. If in doubt, check NASA’s experience! Ramón E.

Your antenna, an off-center-fed Windom, is notorious for generating common mode current on the feedline, and there's no way to choke it effectively to kill that current. So what you're calling a feedline Mother Nature calls part of the antenna. THAT'S a primary cause of your problem. If you're having issues on 80M, you'll need at least 13 turns of the RG6 through a single #31 toroid to make a dent in the common mode current. Grounding the dish is important for lightning safety, but it is NOT part of a solution for RFI. The earth is not a "sump" into which RF is poured. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Jim is 100% correct. The Direct TV receivers are HORRIBLE for noise
generation. Maybe you can't hear it if your Ham Antenna is far enough away but it is there for sure. I bought a Sony model ICF-2001 to use looking for various noises about the house. You don't want the later models as they have auto noise blankers in them. The radio covers AM/SW/FM and does AM or SSB. Jim is exactly correct regarding the Wall Wart type switcher supply on these Direct TV receivers. They are 12.6 vdc so easy for us Hams to pick up a nice small linear transformer powered regulated supply. I also hooked up the Modem and Router to this same linear supply. Yes every one of them made noise. Next the HDMI cable from the Direct TV receiver to the TV set also mades lots of racket. I use TWO of the FT-240 mix 31 cores and managed to get about 5 turns through both chokes. That killed the HDMI cable noise.
