[Elecraft] Female Plugs for K2 Mike Header

[Unifiedtx at aol.com]

I have wanted to use different mikes with my K2s, so I made up some plugs 
that fit the 16 pin mike header.  I wanted to eliminate the 8 jumpers, and I also 
wanted to eliminate the 5.6K resistor at the back of the mike connector.  
Making up plugs for the Elecraft MH-2 and various Kenwood mikes is easy.  Making 
up plugs for Icom and Yaesu mikes is a little more difficult.  The 5.6K 
resistor is mounted between pin row 1 and 6 on the plug for the MH-2.  The pins in 
each row are bent towards each other flat against the plug and soldered 
together.  One pin in row 1 and row 6 is bent to the outside for the resistor.  Make 
sure the pins in rows 1 and 6 are soldered together.  For Kenwood mikes all 
pin rows are soldered together except row 6.  Row 6 pins are cut off.  The plugs 
I used can be purchased at Mouser for $2.38 each.  They are Mouser stock # 
649-68683-308, 2x8 DUBOX .100 vertical PCB mounted receptacle assemblies low 
profile and can be found on page 785 of catalog 618 May - July 2004.
