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

[Owen B. Mehegan]

...walk into a bar... Just kidding.

I've had my K2 for almost 2 years now, and in that time I've used it  
almost exclusively for PSK31 and occasional forays into CW. I have an  
old Yaesu desk mic that I wired up for it, but I never really use it.  
I think I'm going to purchase an MH2 hand mic, but I noticed in the  
instructions for it that I will need to add a bias resistor to the  
microphone jack on the rig. I use a SignaLink USB interface for PSK31,  
which connects to the mic jack. Is adding the bias resistor likely to  
cause me any difficulty with the interface? Some specs on the  
interface are available here: http://www.tigertronics.com/slusbmain.htm

Thanks in advance!
