GA  Everyone

I hope this has not been answered before, but I could not 
find my answer in the archives, so here goes.

Can anyone tell me how much bias the microphone is able to 
tolerate?  Since the battery pack supplies 3v
dc, I am sure that 4-5 volts probable won't hurt.  But how 
about 10-12v DC?

I use my headset with my K2, but would like to try it with 
another rig that supplies 10v.  To get my other rig voltage 
down to the 3-4v region require about 12 meg ohms in series 
with the 10volts supplied.

All of you guys and gals are a great source for info 
regardless of topic and I wish to thank all and any of you 
who choose to answer my "novice" question.  I have learned 
something in my years on this earth, that if you don't ask 
you do not get any answers.

Thanks again in advance.
