[Elecraft] K2 SSB Problem

[iz1dug at libero.it]

Hi,

I just finished installing the KSB2 module on my K2 QRP version (full optional).  I go to operate for the first time but when I push the PTT I get this problem:  the current absorbed increases (the voltage decrease) until it exceeds the value 4 A (set at this value after some test) and the K2 switch off.  The current and the voltage values reading on the K2 display and on the multimeter are the same. I have this problem on all band but only in SSB mode (K2 works correctly on CW mode with full power 10-13W). The problem is repeated every time when I push the PTT. 
I use the microphone Heil MH-2.   
Any suggestions? 

Good weekend 

Ciao,

IZ1DUG, Fabio

K2/QRP #1702 and K2/100 #5909
