Not sure what you mean by the microphone had to be completely rewired...a 
microphone is a pretty simple device...there are two wires involved that go 
to the element...
There is a body ground on a studio mike, and if you purchased an unbalanced 
mike cable this may have caused some buzzing or ground issues or something.
I've used studio microphones for years on my ham gear and it's always a 
pretty simple process to wire them up...A standard xlr type microphone cable 
has 3 wires in it, an audio hot, audio ground, and shield which is usually 
used as chassis or body ground.  For purposes of connecting to a radio, the 
audio ground and shield can be tied together.  Your radio has an audio hot 
pin, and a common ground pin on the microphone input jack.  I simply chop 
off one end of the xlr cable and wire it direct...
So, tell us, what were the issues that you ran into?  Are you trying to use 
a condenser style microphone?  Or a ribbon mic or something like that which 
requires voltage to operate and thus had to get power to the mic?

Subject: That 1 you know what the pooch

Hi all:
Bought a studio mic and cable and apparently after having a buddy try and
get it working, both had to be completely rewired.
So that makes me wonder if an hm12 and cable would have to go through the
same? I thought a studio mic would have better grounding and be more
durable to handle rough duties etc.
Another lesson learned.
