I have been using a pair of Km184s for a while now and enjoy their sound on the chamber music work i do, but i have been running into a fairly regular problem that i dont remember ever having with other SDCs, like DPA 4011s, AT4051s, schoeps cmc64s, etc. i am, on occasion, picking up a "bz bzz ... bz bz bz", which someone told me was a cell phone re-establishing its connection with the nearest cell tower. it has wrecked more than one nice take, in that i do not know how to get rid of it, or how to prevent it.

any thoughts, suggestions, tips on getting rid of it, etc, would be appreciated.
