[Elecraft] microHAM K3 cables ...

[Dave Yarnes]

I was under the impression that the K3 was wired the same as Kenwoods for 
microphone usage.  However, In checking the Heil website, and the subsequent 
link for mike connections, they show that pin 5 is 8 V., whereas the K3 
manual shows that pin 6 should have 8 V.  Actually the website for Heil 
doesn't really show how the various adapters (I.E. for the Heil Traveler) 
are wired.  It only links you to the website of G4WPW for a description of 
various pinouts for various rigs.  What's the deal?

Also, the K3 manual specifies a low impedence mike (600 ohms +/-).  Nothing 
on the Heil website that I have found actually discusses what the impedence 
is for mikes like the Heil Traveler or Pro Set.

I'm also curious why my Heil Pro Set headphones seem to have low output 
compared to other headphones on various rigs that I own.  Anybody know what 
the impedence is for the headphones?
