[Elecraft] K3 + MK II HELP Needed

[ik0yvv at libero.it]

Hi Guys,

i've taken a Microkeyer II with his cables for K3 ( the one with the rear jack 
for mic ), i've been able to set-up everything for RTTY and CW, but i'm having 
big problems with phone and PSK31/JT65 .

I've connected an condenser mic to the rear of MKII with the supplied RJ45 
adapter , but , not way to let the audio arrives to the K3, just the ptt but no 
audio (i've setted the internal switch of the MKII for the condenser mic ), the 
same problem occured on PSK31 and JT65 ( in DATA mode ), the program can drive 
the PTT but the radio doesn't receive the "audio" from the MKII .... i've done 
almost every kind of test and set-up in the K3 , but i cannot find the 
solution.

Any suggestion ?

If i record an SSB buffer in the MKII with the computer mic and send it into 
the K3 the radio trasmits properly.

I'm not a tecnician, so i do apologize if my question is very silly.

Thanks in advance.
