Two other items to check:
1. intermittent problem with the microphone on your headset, especially if it is an electric ANR type set. I had a similar issue with GYY tower - drove us all nuts. I only had this problem on first flight from the tower [moisture condensing on the mike?]. have two Lightspeed headsets, and I only had this issue with the primary set - a 20 series. No issue with the 15-series unit as long as it has good batteries in it. The unit gets goofy right before the batteries become too weak to drive the ANR.
Just 2 weeks ago I sent my primary unit back to Lighspeed for a checkup. They replaced the mike [for free] to correct an "intermittent feedback" between the microphone and the electronics.
2. If you are using an ANR set, check if your auto squelch on the radio is interfering with the headset. Again, I had a friend who wrassled with this last summer, only to discover the auto function on his radio was fighting the headset. He shut the function off, and all was fine with the tower.
Finally: a Pirep from a friend who has owned a Lightspeed ZULU for 3 months. He loves it. Very light, very quiet, and it has an MP3 jack feeding his player into it, with auto volume reduction during all incoming/outgoing radio calls. It also accepts bluetooth from a player or phone. I'm buying one to greatly simplify my audio plans!
Good luck,
John

Steve -
This is strange! I fly into KOUN regularly. When I fly in, I'm
communicating with flight following with no problems, and transfer off
to KOUN okay. The next day, sitting on the ramp, radio cold, they tell
me that my radio is unreadable. I've had the radio checked out
throughly by two different radio shops now 4 times. Now it is starting
to happen at another airport KSAG. Yet, I taxi across the field at
KASG, the radio shop does a check, call up tower, and everything is
normal. Makes no sense and I think something is wrong with THEIR
radios. And no, it isn't wind noise. I've tried everything, even my
handheld, and at KOUN, they say they cannot understand it either,
although at KASG, the handheld usually works. I keep telling them that
they have something wrong with their system, which has now made me
almost persona non grata at their facility. I'm using an ICOM radio and
have had absolutely no problems with anyone else reading me other than
those two places, and was all over California, Texas, New Mexico, and
Arizona with it last December and January, with no problems whatsoever.
I use flight following on every flight, and occasionally someone will
tell me my radio has some background noise, but I've gotten in the habit
of asking for radio checks and always get a good report. The only
places I have problems is KOUN and KASG, and usually only on initial
call up. Once I'm airborne, they can generally hear me fine.
I'd say we have a similar problem - let's stay in touch until we find
some way to resolve it.

I fly an open cockpit experimental (Pietenpol). My radio is a Vertex
Standard VXA-150 (handheld), powered by an external 8AH/12v battery.
I have an antenna mounted on a ground plane on the belly, in front of
the gear. I have no problems communicating air to air with other
planes, I have actually maintained contact air-air with friends at
distances over 125NM. My calls were reported as loud and clear. I
was based at a class D airport (KFTW) for about one year, and never
had trouble with the tower there.
Two years ago, I moved to a new area, near a class D airport that I
occasionally go to (KOUN in Norman, OK). I often have trouble being
understood by the tower, even though all pilots indicate that my
transmissions are loud and clear. Last weekend I tried to enter the
class D, but both times I called, the tower responded saying that my
transmissions were "scratchy and unintelligable". I was about 6NM
away and could actually see the tower. I immediately switched to
another frequency, and heard traffic on the CTAF at KGYI, about 95NM
away. I called them and asked for a radio check. That pilot replied
that I was loud and clear. Not wanting to bother the tower or cause
trouble in their airspace, I turned away before entering.
I am baffled by this. What would cause me to be unintelligable to the
KOUN tower repeatedly, when no one else has trouble understanding me,
even at long distances? I was on a heading for the tower, and I know
my transmission strength in that direction (forward) is good. AND it
was only six miles away.
My only theory is that the tower doesn't like the wind noise in my
mic...but I have a noise cancelling mic, with a leather wind-blocking
mic cover, AND other pilots report my transmissions as clear.
Any thoughts on what might cause this would be appreciated. It is
difficult to trouble shoot because I have to bother the tower to
replicate the problem.

Thanks John -
I use a regular David Clark 10.13 Headset and with M-7a noise canceling mic. If there are problems again, I will check the placement of the mic. I keep it just off my lips, as per instructions, but there could be some interference. thanks for the tip. I also have a pair of Lightspeeds I bought from my neighbor, but have never used them.
