<<I want to hook up a mic to my HT-37........Is a Dynamic mic a high 
impedance mic?>> 

As Glen pointed out, most dynamic mics are Hi Z, but most dynamic mics
used 
in the broadcast industry are Lo Z.  Some have impedance changing
switches on 
them, others can be changed by the wiring in the connector and still
others are 
permanent Lo Z instruments.

You didn't mention what mic you were using, but if it is a totally Lo Z,
you 
should try to find a Shure A86A In Line transformer.  This is a really
neat 
impedance matching tranny that goes in series with the mic line.  It is
well 
shielded and eliminates the need for a mickey mouse inpedance matching
setup.

Best place to look for one is....believe it or not....a music store that

sells band equipment and PA systems.  I have never seen one at a hamfest
or it 
wouuld be mine.  I only have one and it works well with an EV-635
broadcast 
dunamic that I have used for years.

73 and good luck,

John,  W4AWM
