Geert, From your description of the "straight connections" and round plug, I believe you are referring to the MH4 - the original question was about the MH3 which has a 1/8 inch TRRS plug and resistors in the microphone for the buttons. The MH4 is usable with the K2 and K3, the MH3 is usable

I have repaired several of these for ZL amateurs - by a similar method. My theory is that the large lump of steel plate (27g) in these mics could contribute as it means the mic has more kinetic energy when dropped. Three of the mics I repaired were damaged in shipment from USA to New Zealand. When

I worked in a factory making injection molded plastic items, which I presume the mic cases are. If the machines are not adjusted properly -- temperature, pressure, dwell, cooling, etc., it's possible to make parts that are extremely brittle. Sometimes the stress of assembly and shrinkage over

Ian, Elecraft has had a 'rash' of those incidents, but I thought they addressed that with the mic vendor (yes, Elecraft does not stock parts for the mic, they buy them whole from the vendor). There was some speculation a few months ago about the cause -- and I don't know the answer.  Many

I like to mix in some short lengths of fiberglass with the epoxy. It provides the strength while the epoxy provides the "glue" holding everything together. An example is repairing the ashtray cover on my 1993 Mazda Miata (with 300,000+ miles). I repaired it at least two years ago, and it is
