A few thoughts...
1) It is possible you were given bad advice in the beginning. Saying
your signal is "wide" is a somewhat vague, unscientific term; it hardly
qualifies as a "term of art" all operators might understand as having a
settled or universal meaning. It is possible you sound just fine, and
have no problem at all. This depends on both your rig AND HIS, as
sometimes the problem is in the other guy's receiver and not in the
quality of your transmit audio. Moreover, this is subject to the the
very subjective opinion of other ops, and some guys have odd opinions of
what constitutes good audio, and, perhaps, what one ham "wide" is what
another ham would call "full" sounding. The trick is to know whom to
believe.
2) I often counsel operators with new microphones to sample the audio
from the mic (and preamp /phantom power source) with a known clean
computer sound card. Recording your voice on the computer can tell you
a lot about a microphone's particular characteristics, such as how close
you can speak to it before you over drive the electret capsule, and what
distance range produces a "proximity effect" (i.e., producing deeper
bass use up real close and producing a thin, treble sound farther away)
so you know the sweet spot where you sound the best on the microphone.
That will also confirm you are not over-modulating the preamp input
and help you select an appropriate starting output for the radio.
3) Could you reply to the two comments that you are NOT running the mic
signal through the front panel mic input? This is hugely important and
could easily account for distortion on the signal. You ARE connecting
the output from the VR-2000 to the Line-In input on the rear of the rig,
right?
4) Although I don't have a VR-2000, I have used similar equipment, and
I doubt you can use just the phantom voltage on the unit, without
engaging the pre-amplifier setting (which sets mic volume level to
Line-level signal strength - see 3) above) and this is key to your
success because you MIGHT be inputting too strong a signal into the rig
to start out - you must adjust both the pre-amp volume out and the rig
line-level input into the radio. Having either one too high will cause
distortion in the rig, regardless of what the other is set to.
5) While I don't want to diss TT out of a sale... you should be able to
get this equipment to play nice with the rig. There is no reason to buy
a different microphone. But not knowing all the settings and all the
connections you are actually using, makes it more difficult to diagnose
the problem remotely.
6) One way to get this done quickly and easily is to phone another guy,
while in contact over the radio, or to work over the radio alone, and
walk through the process and listen to changes as you make them.
In any case, I would counsel you to review the connections, and start
with a low pre-amp output setting, and low rig MIC input setting, and
accept a weak, or anemic signal to start out, and work up to a more
robust setting - while working with someone with good ears and good
judgment on a receiver someplace.

Great fellows..Thanks for all the advice on the radio..Just to answer a few
questions..This is a new radio from the factory..one week old..I do not run the
speech processer at all..I was told that I was to wide..the audio sounded
fine..just to wide..I'm going to run the audio into the back of the radio with
everything on the VX-2000 turned off but the 48volts that the mic needs..if
this doesn't help..I will call and get a new mic..either the 706 or the 709...I
do really like the rig on rec..once I get the audio set right it should be
fine..I think I will call TenTec now and see what a mic will cost me and just
get rid of the other stuff I have here..sounds like I don't need it..I'll let
everyone know the outcome..73s Bob
