>>889939Yeah the mic is kill. I cleaned the contact pins and it seemed to help but the problem is intermittent at best, so I can't trust it out inna field. It had been packed in silica gel for several weeks so it can't be moisture either, guess after a couple years of being out in the elements the capsule is finally fried.
BUT i replaced them with nicer mics! The last pair was quite good but these new ones are much better, about 10dB less noise and better overall response. They are sensitive to humidity though so I gotta be careful with them '~'
Here's a recording with them though, they're so nice and clear. Just a plane going by sort of far away. (also it was a very windy so all the "sssssshhhhh" you're hearing isn't mic noise, it's the wind in the leaves).
