[Elecraft] K3 and David Clark aviation headphones

[David Moes]

Will my DC h10-40s work on the K3?   I am using a David Clark h10-40 
aviation headset that I modified with new connector and cable etc to 
work with my kenwood ts430 rig and it works well with good reports and 
nice audio in the earphones.  I was wondering how well the K3 will 
work with these,  the mic is a 150 ohm noise canceling electret that 
needs minimum 9V according to DC specs, but  seems to work fine using 
the 8V on the kenwood mic connection.   Will the K3 work OK with a mic 
at just 150 ohms?   I realize I'll have to rewire the 8pin mic 
connector on the headphones  since the wiring is a little different 
than the kenwood with the 8V power is on a different pin on the K3.   
I love these headphones as they are dead quiet both at the mic with 
its noise canceling, and in the earphones. Perfect for working in a 
noisy place like a tent full of loud ops  on field day.
