I lent my Rode NTK to a buddy of mine that has a recording studio that's using an alesis fire wire mixer and strangely enough the NTK seems to be picking up, I'm not making this up, gospel radio. He switched back to his samson multi condenser and did not get the gospel radio. Every time he plugged in the NTK he got the gospel radio. Any ideas, comments?

The NTK has a high level of RF rejection so somethings acting as an aerial.

Try changing power cables, move to another house power outlet, try changing the NTK ground lift switch.
Cheers.
