Hi Colin,
I never run my mic level at 100 percent. I don't want to flat top. I was
running the hand mic that came with the 2000 at about 40 percent and my
current MFJ 297 mic is running at 25 percent mic level. I get between 100
and 104 watts out of my ts2000 at these levels.

yep, fm audio is very low on that rig without the compresser on.
this sounds like a great mod.
however, with 100 percent mike level, everything seems to work just
fine...audio is good, and power output is right at 100w or 101W on ssb.
So, my question would be, if this new element is being used in normal,
average operating conditions with 100 percent mike level, does it then over
modulate because it is seemingly so much hotter than the stock element?
I personally don't know many people in the real world who set their mike
level at 50percent and expect the radio to perform well.
the ts2000 will also only put out about 5 watts with the mike level at 50
percent and the stock microphone...yet it's considered to be an average
relatively decent microphone.
I think this is probably an excellent mod for the 7000's mic, but the
testing parameters in the youtube vidio were a bit interesting...sort of
made to show the bennefit as aposed to showing realistic results.
just my two sents.
If i ever got the 7000, i'd probably get something similar done.
