[Elecraft] K2 Microphone Help Needed

[Kerry D. Fitch]

Hello,  I was given a K2 qrp rig with the SSB option over the weekend.  I got a chance to play with it a little bit with a K40 mag mount antenna and I am verry impressed with the receiver in this little raido.
   
  Now I want to get it on the air but unfortunatly it didn't come with a mic as the previous owner used it for PSK-31.  I rummaged around the shack and came up with a couple of options.
   
  1) Turner Plus 3 amplified desk mic
  2) Kenwood MC-50
  3) Motorola Mactrac compact palm mic HMN1056D
  4) Midland cb hand mic.
  5) Drake 1525EM hand mic from a Kenwood TR-7500.
   
  Now I know the Turner and Kenwood mics should work just fine once I wire up an adapter cable from thier 4 pin config to the 8 pin on the K2 but I would like a handheld mic for portable use.  Witch one of the hand mics I have listed would be best suited for SSB on the K2?  I am looking seriously at the Drake as I can use the same adaptor cable as the MC-50.  Also will I need to add the DC bias resistor to the audio line for these two mics?  When I build the adaptor cable I will have to add a switch to cut this dc bias out for using the Turner as it has its own 9v supply.
   
  Thanks
  Kerry
