[Elecraft] DM2

[Charles Greene]

Hi,

About a month ago, I bought an Elecraft DM2.  I don't recall testing it, 
but I tried it today on my K2/100 and it keys the K2 but no audio.  Also 
tried it on K2 462 and it doesn't work there either.  I have a MH2, and it 
works fine on both rigs.  Am I missing something?  I took it out of the box 
and did nothing.  I don't really want to go digging around inside the 
mike.  Are there some quick checks with a VOM I can make to verify wether 
it really is dead or not?

Tnx, Chas, W1CG
