The computer is not powered up 24/7. The laptop was not on, just the power supply plugged in which is the case 24/7. I replaced the power supply and the interference went away and 15 came in great. Problem was the P/S, not the laptop.

btw It was the last thing I unplugged in the room after shutting off the breaker to the room and knowing the problem was there. What an odd feeling when I unplugged the P/S and 15.1 filled in the the screen.

Glad it worked out for you.

Modern power supplies are of the "switching" type. Unlike the old linear power supplies that had transformers and iron they didn't produce this kind of stuff. The upside is they provide a bunch of instant current for a very light weight power supply. Down side is (as you found out) poorly designed switching supplies will radiate RF. Switching power supplies take the 60HZ AC and convert it to a high frequency signal and then filter to get DC. A poorly designed switching supply will cause all kinds of spurious emissions. Also I have seen some of the cheaper CFL (Compact Fluorescent Lamps) be pretty RF nasty as well.

One last question -- I assume you use 75 ohm coax for the lead in. Roughly how far from the antenna is the PS located.

(I've mentioned before that the motor in the Shiatsu Back Massager will totally obliterate 15/3 --that is when used in the living room. Take it down into the family room in the basement and 15/3 comes in fine)

It is on the end of the house as the antenna, I would estimate about 20-25 feet straight line. 75 ohm coax is used.

I tried the P/S in the basement and channels 15 came in without any noticeable problems.

Back a couple of years ago when I was trying to optimize reception on 15/3, I reasoned that all the VCR/DVD/CECB boxes were outputting a signal on channel 3. To be on the safe side I changed them all to channel 4. I can't really say it made any difference but it was easy to accomplish. Any comments? Is interference from a boxes a possibility or is the signal so weak and well shielded that it is a non-issue...

Before we got cable and on the antenna there was interference on Ch 7 and sometimes all of them except for the UHF. I have 3 phase power lines running in front of my house with poles, wire and insulators that are over 50 years old. Sometimes when it rains the interference would go away. We finally got cable for what it was worth and it even got into that. I have checked everything in the house and called the power company with no response. The cable finally got better as the years passed. I like to watch PBS world but the only way to get it is off the antenna. The same interference eats it up too. I can go to my wife's mother's house who is on the antenna and PBS is great. It was a bad choice for WBRA to go to channel 3 and why I do not know. At least the cable does give the locals in HD digital and thankful for that.

Well there goes the PQ on 10.1!!

Too bad they are not planning to eliminate 10.2. I really can do without retro weather -- todays weather forecast recorded yesterday (12 hours ago)

I don't know if they're putting it on 10-2 or adding a 10-3. It's only listed as "WSLS" on the MeTV site.

How should I list it? Bear in mind that I have no confirmation of where it's going exactly, but do want to list that it's coming soon.

10.? might work

But your code is probably expecting a numeric variable

Yeah.

The way I've done it is not ideal, but it gets the job done, I guess.

Such niche programming with minuscule to zero ratings

Last time I checked, on March 8, WSLS had max bitrates:

10-1: 14.5 Mbps
10-2: 3.7 Mbps

Those max bitrates are now:

10-1: 12.25 Mbps
10-2: 1.75 Mbps

Hmm...

Yes, break the mystery and suspense, why don't you.

I had suspected they'd be replacing 10-2 with MeTV, but those bitrates make me think they'll be adding a 10-3, which would not be without precedent for Media-General stations.

No idea. I just happened to check it this morning. I'm about to leave for Charlottesville.

Also, I don't watch sports.

Actually, the only "sport" I watch is NASCAR if I'm bored and feel like seeing wrecks. That's about it.

I haven't seen it for a while, but a number of years ago on SPEED they had this racing with trucks pulling boats on trailers around a track. It was hilarious! Seems like 3 of us at work saw it and it was the big topic of the day since it was so damned funny!

could someone please recommend a good indoor antenna for use in an apartment for me in vinton va (just a few minutes from roanoke)
post #5637 of 6116
Ok.... yesterday night I got hit by lightning (Blacksburg area) . It went through the antenna cable and burn tuner, switch, router, cable modem. Computer wasn't working for a while and then it recovered, but the USB hub is gone as well. The nice thing is that this is the second time this week!!! although last week It got only the tuner and the switch.

Did I do something wrong and if not how can I avoid this from happening again? Right now I have two gage 10 copper wires connected to an 8ft stake (which I hammered in the ground myself!). One wire is directly connected to the structure of the antenna, the other one to the cable through one of those splitter designed just for that.... BTW everything is plugged into a surge protector.

Weird thing is that my preamp (a WINEGARD AP-8700) is fine and I still have signal from my antenna . I would expect that to let the magic smoke out first. I can send pictures if that can help.

Any advice?!?!? Thanks!

Is your antenna grounded with a grounding block like this one? http://www.solidsignal.com/pview.asp...u=615798301453

- Trip
post #5639 of 6116
yep, that's what I meant with "one of those splitter designed just for that". I didn't remember the actual name for it. The second ground is connected to the pole where the antenna is mounted on.

I'm moving to Florida soon. Lightning capital of the world as I understand.
I've done a little research on whole house surge protectors and found these.
Not sure where to start as for finding which are good at stopping lightning and don't have to be replaced each time.
