[Yaesu] background noise

[Andrea De Feo]

Hello to all

I hope this message will be not a little bit off topic, but , probably

could be " interesting ".

I have a barand new FT1000 Mark V and a MD100 microphone. This microphone, 
unfortunately ,

gets a lot of background noise, I mean when a switch my home brew linear 
amplifier on

the noise of its fan probably, a little bit noisy, "enters" in the 
microphone causing some troubles

you can easily immagine.

So my question is is there any electronic circuit to " cut "  this noise ??

Is there anybody have my same problem and have already found the solution.

Any suggestion will be appreciated.
