[Elecraft] MH2 to MD2 - K2, Modification Required?

[Paul Clay]

I built a K2 about a year ago and wired it for use 
with the MH2 hand microphone.  As the MD2 is 
currently on sale, I'm thinking about purchasing 
one.   Can I just unplug the old mic and plug in 
the new one, or am I going to have to modify the 
mic input circuitry?

Thanks,
Paul
