To answer Pete's question first, my parents' Internet connection is currently being killed by interference so I can't update my bitrates. I actually pulled the numbers I have now off the front of the encoders when I was at WDBJ in 2009; perhaps Alan would like to update me? But once their Internet returns, I will update WDBJ based on TSReader output accordingly.

I'm actually rather pleased that Roanoke is finally getting some variety in the sub-channel market. Decades on WDBJ, plus COZI (and soon Movies!) on WFFP. I'm hoping WFFP at some point stops upconverting COZI and Movies! and instead does a collection of SD channels. There's plenty of them out there!

Good to know. I must say that most of the time when you guys (WDBJ) do something you do it right. I have never had any complaints about your PQ.

Disclaimer: Perceived PQ is very much dependent on screen size and distance from the screen, and probably the chip set in your TV. YMMV.

And finally it seems to me that the PQ on WSLS has improved (less macro blocking). I don't know if that's due to a technical change or the content I am watching. (Not very much.)

I've updated the TSReader data for all of the Roanoke stations my parents can see. WDBJ's bitrate on the two SD channels was essentially just the previous My 19 bitrate chopped in half.

Trip - since I don't hear from you much - do you have RUSH tix?

I have one for Greensboro on the 28th- going by myself and have two for the 30th at Bristow. Not sure who I am taking..

Yep, I'm going to the Bristow show on the 30th. I got two tickets but I don't know if I'm taking my fiancee (she's not a Rush fan, but nobody's perfect) or my friend who I saw Metallica with in college.

Are you staying over up here or driving back afterward?

Before you head to the concert how about fixing that state of the art PSIP system you have that can't tell time. Since you added 7.3 the clock has been about 4 minutes slow. It used to be exactly 16 seconds slow.

NBC 29 is exactly 16 seconds slow and since WFFP 24 got their PSIP system up and running their clock is exactly 16 seconds slow. I'm beginning to think you guys might be using the same system and this is a software/firmware issue.

What system are you using? Do these systems normally come with a warranty and a period of tech support?

BTW thanks for going to 24 hours of program information. It has made programming the DVR easier.

The system is locked to house timeserver that is locked to GPS. The system time is right on the money. There are no settings that I am aware of for clock.

I don't think so. Attached:

Screen shot from the Samsung. OSD 8:20 (correct), PSIP 8:16.

Screen shot from the Sony. OSD 8:21, time remaining 42 (If its 8:21 and the program ends at 9:00 there are 39 minutes left)

Finally (and primarily) the diagnostics on the OTA DVR display your PSIP time in GMT and that is also 4 minutes behind NIST on the tablet.

I'm not going to argue with you but I can watch the program editor and when the clock hits the hour the next event is placed on-air. I am not sure what clock you are seeing but I have a lot bigger things to worry about than this.

On my TVs (LG and Samsung), the clock that shows with that info (at the top) is set by the TV, not the channel. I can make it say anything I want - or have it do "auto" but it doesn't recognize DST in that mode.

Thanks. Maybe you can explain it. I am looking at gear that this guy has never set eyes on and can look at system clocks and the real time program guides advancing to the second but yet tells a number of us we are wrong. Just remember he can buy his consumer gear at WalMart. Not so much here.

Moneta-Roanoke signal drops in early evening channel 15 (RF 3)

Tried a 4DB flat panel, but was just in the edge of getting a fav channel (Roanoke WBRA virtual 15). Spent a couple of years playing the aiming game, but even in best of conditions, just couldn't get reliable reception on this channel ....all other channels were above drop out, so issue is just with this one channel.

Got an Xtreme Signal HDB8X-NI 8-Bay VHF/UHF replacement, and kept the mast mounted pre amp with the indoor mounted Channel Master amp - about 20 feet AGL. Better reception on all channels, including the PBS channel 15 (30.1 miles' 283 degrees from antenna mount in Moneta, VA to the broadcast antenna on Roanoke).

But, channel 15, which stabilizes in best conditions on the Sharp 60" digital meter at 63-66, degrades to 35-40 (used to degrade to zero with the 4 bay antenna) and starts to drop out with pixelation from around 7 pm until around 9 pm. At 9 ish it returns to stable 63-66. Even in bad weather, the decrease isn't as bad. It ONLY happens at this time of day.

I understand some of the issues wrt temperature and atmospherics ...but, this seems rather extreme.

Looking for ideas to get back a few db ...or is this the problem?

Is it consistent or only on certain days? Summer is the best time for e-skip which does demolish low-VHF signals, even strong ones.

From memory - it had been more prevalent in the summer months with the 4DB antenna. I don't have non-summer data on the 8DB antenna since I just installed it.

Read a bit on e-skip ... since the issue occurs only between 1900-2100 (I need to be more attentive when it starts and stops, but this is a reasonably accurate approximation) .. how can this be e-skip.

I need to ask around to find others with OTA to see what their experiences are ...

And, since the signal the previous antenna supplied - on the same day at nearly the same time (1900-2100ish) - was zero, and now the signal is 35-45, it would appear the larger antenna with obviously great gain has improved the situation, but not closed with enough margin.

Based on this does it really sound like E-skip?

No, it doesn't, but it still could be some kind of interference. There isn't an automated timer light or something around that runs during that time frame, is there? Does the signal have a sharp and sudden drop or is it gradual over a period of minutes or an hour?

Him again, Trip in VA,

I have a couple of automatic, motion detector lights outside the house ... but they are 50 feet from the antenna and the coax coming into the house ... and, they have not been on when the decrease in signal has occurred.

To make it more confusing, we were out of the house until around 2130 last night and when we returned, Channel 15 (actual 3) was fine with around 65 signal, BUT Channel 27 (27.1 and 27.2 both from Roanoke) were zero. This morning, 15 was fine, again, and 27 was much lower signal than normal .. still viewable, but around 45 on meter.

The mast does has an attached anemometer that faces the receive side of the antenna ...it appears to be all plastic, but the blade portion does spin at various rates and moves as the rudder realigns it with the prevailing wind direction. Reception does not seem to be related to wind speed or direction ... could it be related or affect reception signal in some manner? (was left on mast well out of reach by previous home owner).

Thanks,

My guess is that last night would have been atmospherics. WNCN in Raleigh and WUNE in Linville are both co-channel with WFXR and in the right conditions could easily have wiped it out.

The issue with channel 3 is that electrical interference from light ballasts and other electronics, whether inside or outside of your house, can cause problems. WBRA becomes unwatchable at my parents' house while the vacuum cleaner is running anywhere in the house, for example. When I lived in Roanoke for a summer, a neighbor using an electric lawnmower made WBRA unwatchable. This is why I'm asking about electronics that might operate only during that time.

I've noticed that LED light bulbs and laptop computers can cause severe interference with TV reception.

Update ...we cut off the anemometer and did a bit more repointing (2-3 degrees at a time ...in the range of about 280-295 degrees) in the late afternoon with light rain and clouds.

Improvement on all channels in the Roanoke corridor, including 15 ...best metric in the Sharp TV was 72 and on the Vizeo smart TV it showed 100 (perhaps not as accurate a device).

I'll keep monitoring and report in if anything substantive changes.

Thanks for the help!!
