[Elecraft] USB Sound Adapter

[Jim LeFevre]

Simple question: I also jumped at the first message, what a deal, as I would like to get going on JT65 in a couple weeks. I ordered and received the same bubble pack, same (looking) dongle, but it clearly states on the "manual" that the mic input is mono. Is it not what it appears, like, is it a "stereo" jack that takes two signals in with a common shield? Thanks, Jim WN8A

I
 purchased two of these devices from Amazon right before someone on this
 reflector posted that the one he bought got very hot to the touch and 
the seller took it back and refunded his money.

I now have two of
 these and neither has even gotten warm.  Both seem to work fine.  Can't
 believe no shipping charge as they arrived by USPS from China!

But
 be careful.  There are several models that look alike externally.  But 
only one has stereo microphone input.  This is the one with stereo:
SYBA USB sound card
SYBA SD-AUD20101
VIA ENVY VT1620A

It works.  Haven't tested it for noise, etc., yet.
