[AMRadio] mike hu-m-m-m-m problem

[W3CRR]

I'm having tons o' fun with my "new Collins 32V-2, BUT, I've got a hum 
problem. According to several listeners, my Heil Classic microphone -- 
while sounding great otherwise -- may be picking up EMI from the nearby 
transmitter iron.  The mike has no internal humbucking coil.

Has anyone else experienced this problem with dynamic mikes and heavy 
iron?  If so, how did you solve it, please?

Many thanks and 73,
