[Elecraft] A K2, an MH2 mic, and a digital interface

[Don Wilhelm]

OK "T.S Eliot" (sign with your real name and call please).

That link does not give a schematic, so I cannot give a specific 
answer.  If the interface provides a series capacitor to block the DC 
then it will work just fine with the microphone bias resistor required 
by the Elecraft MH2, but if there is a DC path to ground (through the 
transformer) the bias resistor will be a problem.

I think the folks at Tigertronics (and other interfaces) should be more 
free with their schematics, but alas, they are not - maybe they are 
hiding their details.
