Charlie, It is difficult to answer from only the wire colors without any diagram. Those colors in the cable can mean most anything - except the shield is ground.
According to the Astatic .pdf in G4WPW's extensive list of microphones, the wire colors are: White (audio), Shield (AF Ground), Blue (switch common), Red (PTT), Black (RX Control - no use for most transceivers), Yellow (Receive Ground - seldom used). These colors are for the wires inside the stand - take the bottom cover off to see them. Then you could determine which of those wires connect to which color in the cable. Use your head and your ohmmeter to be certain. Someone may have rewired it according to their own definitions of which color is what. Those mic stands may have been through a lot of hams hands. Work with the colors in the stand rather than the ones in the mic cable. One thing you could do is to confirm the two that are used for the PTT switch - connect two of the wires to your ohmmeter and close the PTT - the two that show continuity when the switch is closed are for PTT - if one of those is blue, that goes to pin 7 or 8 of the mic plug, the other is the PTT line. Examine the wires more carefully to see if one is a shielded wire - that would be th AF and its return would be the shield. The AF connection is to pin 1 and the PTT connects to pin 2 - the returns connect to pins 7 and 8. 73, Don W3FPR On 6/9/2011 2:25 PM, CHARLES WHITE wrote: > And now I have another problem of how do you connect the 8pin to the 4 wires > from the D 104? > There is a schematic on the inside of the mike bottom plate but does not > address the from 4 to 8 pins. > There are 4 wires in the mike cord; a black, a red, white, and copper for > ground. > > I assume the black and red are for the mike and the white for PPT. > > > Charlie White > K6TBB > San Diego > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
