[Elecraft] Heil Traveler Headset w/K2??

[Steve_wG0AT]

Can anyone tell me if I have the correct Jumper Block configuration on  
the K2 for my Heil Traveler Headset? (Not the ProHeadset but the  
Traveler)  I'm using a Kenwood 8-pin adapter cable HSTA-K8 for the  
headset. So far everything seems to be working FB except for the audio?

I followed the Kenwood setup (2nd table) on P18 of KSB2 SSB adapter  
manual.
jumper block setup as follows:
AF -    1  JUMPERED
PTT - 2  JUMPERED
DN -  3  JUMPERED
UP -   4  JUMPERED
Func- NC JUMPER REMOVED
5V  -  ?   JUMPER REMOVED
GND - 7 JUMPERED
GND -8  JUMPERED

Results are no mic audio? Suggestions (besides tossing out the headset  
please!)

Tks Steve
