It should be noted that ATSC TV tuners do not give the actual channel frequency that is being used,
Every one I have used (I have never used a VIZO) you can go into the menus and usually add channal, manual add, and it gives either what I call the carrier channel or both the carrier channel and the actual frequency.... (That is the frequency the station broadcasts on)
Your Sensar Pro (in an RV) will show the Carrier channel so I use tune the TV to the station that almost is good. then go to manual add and change nothing but note the carrier channel.. set the Sensar Pro to the same number.. and peak the signal.
Home was where I park it. but alas the.

Ran into an acquaintance that is actually a tv station chief engineer this weekend. I couldn't do anything yet, as it's been way too windy to play with an antenna on the roof.
.
His suspicion is one of the cable has a shield wire strand contacting the core wire. I can easily pull the living room tv off the splitter and check the other two TV's. I've had other projects taking up my time this weekend. Because the behavior didn't change when I disconnected the other TV's from the splitter, it has to be in that line, and that wire and installation is all me. Can't blame Quailridge for that ![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile")
There is two other possibilities, the antenna has a "short" and he advised me to look carefully at the cross over elements to make sure one isn't shorting out. The short lead on the antenna to the balun also hasn't been changed out.

Made some progress today.
2' long RG6 between balun and preamp had some "debris" where the insulation was cut to the core. Not exactly sure what it was, but it also looked like some shielding was close to the core. Cleaned it up best that I could, but need to replace that cable. I had a 3' piece, and it made things worse.
Completely lost one channel, which boggles my mind, as the other channels are stronger now. Antenna is in the exact same position, as I have the pole pinned.
Think I also figured out why I can pull the signal in and out, I have about 40' coiled right under the bed. I roughed it up a little, so it's not a pretty coil. I'll deal with that later, was pretty done after several dozen trips in the crawl space and back to the roof. I did use the creeper under the add on roof, crawling under the trailer gets really old. Only bad part, if I was any plumper, I wouldn't be able to sneak under the HVAC ducts.
Did happen to finally take a look at one channel that has come up with 2 or 3 different times doing a channel search. On the one TV, it showed the station is broadcasting on two different frequencies. Wonder if they or the FCC know they are doing this. Might have to drop a dime I should do a rescan, because I have seen on one TV, three duplicates.

In Minneapolis where I live there are at least three stations that have two transmitters. Through the magic of virtual channels (PSIP) these appear to come from a single transmitter. For instance, channel 5 is broadcasting on RF channel 30 and RF channel 35. These are displayed on a TV as virtual channel 5.

I've never seen this anywhere else in our travels. And it's just one station
