FAQ

FAQ

Q: How is the MH4 different from the MH2?

A: The MH4 is a direct, plug-compatible microphone to the MH2.  Unlike the MH2, it is housed in a smaller form that fits into the hand easily, making it easier to store or carry.

Q: The MH4 looks very much like the MH3 used with the KX3 and KX2, can it be used interchangeably?

A: The housing used for the MH3 and MH4 are the same but the connection plugs are different.  For that reason, they are designed to be connected to their respective radios without an adapter cable in their native form.  The enterprising ham, however, is welcome to build adapter cables.
