Audio dropouts on OTA

[TT123]

:bang: I am getting a real education about digital TV. Having stood radio guard in the USCG and heard Coast Guard Kodiak Radio each night from the Hawaii in the early 70's RF for Avionics and Sea Going Vessels I understand. What's happening with the signals between my hilltop home hear Brookfield Square and the Transmitters is new. Strange like moisture in radar waveguides on 82ft Coast Guard Cutters that took a beating in Nam by friendly fire.
I had my Electrical Service upgraded this summer. I borrowed a digital Signal strength meter and rewired my home with quad shield RG6 T&B Snap-N-Seals and well did it all by the book in preparation for a new flat panel HDTV.
So why
1.   Audio Drop outs on three stations now 36.1 4.1 and 12.1. on my new 46 inch Sharp.
2.   CBS 58.1 HD volume is so much louder but no dropouts (digital like when it goes to local programming about the same).
3.   Could my new CM 3018 be too much antenna for signals 11.6 miles away and picking up multipath that bingo cancel only a portion of the broadcast (audio) and spoil the experience? The Pixelation is fine.
Should I buy just a simple Weinguard Ghost buster vhf a CM 4221 uhf add signals with a splitter/combiner and feed the lot down the line?
Could I have a flakey tuner computer/ram problem I should be stressing with a signal generator by a repair professional with the gear to hammer away at a different problem with?
There is always TWC but... OTA is free and I love PBS 10/36. I do not like the TWC story here in Milwaukee and trees to the south are a real problem not that I don't have a problem to the north east to the transmitter (they're all about in the same spot from my location only the freeway and very tree tops are a problem).
Any Ideas?

It sounds like you have done all you can in terms of building your reception system.  In terms of the transport stream, the audio and video information are embedded into one big pipe.  Therefore I don't think you have a reception problem if you are only having problems with audio.  This may be some hardware bug or other problem.
Hopefully others here can chime in with their words of wisdom to help you out.

Circuit City's operations manager sent me a new TV on Christmas Eve. Seeing a TV repair guy that hadn't even come to the house to see what I was talking about had been too much. We bought the set Veterans Day on sale and later saw it at $800 off on Circuitcity's website. Money back to the tune of $540. Had we waited we could have bought the set at the Great Lakes  Navy base Exchange (I'm retired U.S. Coast Guard)f or the same price $2499.00 and paid no tax but then I wouldn't have had Elizabeth to send us a new TV, set it up and check it over good on Christmas Eve and make the family very happy.:hug:
I was nice to the TV repair guy. I did what he asked over the phone. I just thought I would voice nicely my displeasure at our situation over the phone to the boss at a great store I send friends to when I spot a great deal.
