Thanks for all your help!
When the weather/seasons change or at certain times of the day, if you start noticing A/V dropouts, you may have to get the antenna out of the attic and away from that ductwork.
Would you mind posting your tvfool results again? I cannot find it. Use the "Mapping Tool" and drag the red map marker over your house, before clicking "Make Radar Plot"
Then, post a link to the Radar Plot page. Your location will not appear on the radar plot page. Thanks
When you mention multipath signals being horrible, what are you referring to? IS there some way I can check this. I'm just curious.
Here's my tvfool results again.
Re your TVFool, I found the original one you posted in the other thread. This one appears to be identical. Was it based purely on address entry or were the results pinpointed over your house, using the mapping tool?
The tvfool location was based on my address but the location where it dropped the pin is right about where I put it in the attic.
My TV needs a SNR of around ~15dB or more to keep a lock on a channel. If it dips below that, I get pixelization, and audio dropouts. Every tuner is different, but you should be able figure out about how much signal your tuner cards need, by looking at the SNR whenever you experience dropouts, freezing or pixelization.
With analog, it was easy to see if you had multipath problems. There would be ghosting on the screen that worsened in proportion to how bad the multipath was. With digital, you need a spectrum analyzer. A clean signal would look like this, and has been compared to the "hair on Bart Simpson's head"... A multipath signal would have high peaks & valleys instead of a consistent "Bart" pattern.
If my problems return with KNWA or KPBI could I just use my old RCA ANT806, which is currently still on the roof, and mount it to the post in the attic pointing NE? If so, do I just use a splitter in reverse order just before the pre-amp connection?
It's usually not that easy, although joining two antennas together in that manner will occasionally work and is worth a try. But it's a crap shoot and it may do nothing but degrade your overall reception.
Probably the best thing you could do is get the 4228 out of the attic.
DTV Innovations which make the PSIP inserter are connected in remotely and looking too.
I currently have a similar problem on Eureka Springs station, KPBI, ch 34. 34-1 (RTV) is fine, but 34-2 (Univision) has no audio. This glitch on 34-2 only affects one of my tuners, a Kworld set top box. All other tuners in the house ignore the problem. I never watch 34-2, so it is not an issue. Luckily with KHOG's problem, I can just flip over to KSPR, Springfield ABC affiliate. Other viewers farther south may not have that option...
6:30 pm-How i met your mother is the show that is on.

In the last couple of weeks it seems that these channels are back on for me. Signal quality is stable. I am guessing that something was changed after one of the semi-recent storms.
Has anybody had problems with 40.2 in Fort Smith? I don't watch anything on that channel but my wife has reported issues with the recordings of America's Next Top Model. Every time she complains, I check the signal and it is solid. Seems like our signal gets bad right when that show comes on but is fine the rest of the time.
If you're talking about the new KFSM signal, probably not very good. Their maximum ERP is only 15 kW. But you'll never know unless you try it.
