Hello Giulio,

That mic will work just fine with a K3. I use an RE16, which is 
electrically quite similar. A correction to the link that Don 
gave you. It's

With any pro mic, you should adjust the TX equalizer to reduce 
the level of the lowest audio bands and boost the level of the 
two highest bands. The TXEQ settings in my K3 are:

  50  -16dB
 100  -16dB
 200  -10dB
 400   -3dB
 800    0dB
1600    0dB
2400   +3dB
3200  +10dB 

To set mic gain and compression, follow the instructions in the 
K3 manual. My compression control is set to provide an indicated 
10-14dB on the compression meter on peaks. I'm a serious 
contester, and my rig consistently gets reports of excellent 
audio from other serious contesters, including some who are also 
audio engineers.
