[Elecraft] MH4 Mic on a K2?

[hawley, charles j jr]

The Elecraft manual says the condenser type MH4 mic is acceptable for use on the K2, but I don't see any bias for it in the K2 or SSB2 schematics. I never had a mic for the K2 so I thought I'd get the MH4 and maybe use it on my K3s as well.
Am I missing something? Is there bias for it on the K2?
