[Elecraft] K3-Heil HM10 Mic-MFJ-434B Voice keyer

[jerry]

Just purchased the keyer.  Configured the jumper setting inside the 
keyer for a kenwood configuration since I read that it would work for 
the K3 and MFJ doesn't give you any configuration for the HM-10.  The 
keyer works but I can only use the internal mike to record a message.  
Anyone configure this setup?
Also, I had a lot of noise (like wind blowing hard) coming out of my 
speaker on the K3 when I played back the recorded message.  The only way 
to stop this annoyance was to disconnect the ground wire I had attached 
on the GND lug on the back of the keyer.  Any thoughts on either of 
these 2 issues?
Tnx Jerry K9PY
