Phil, To match the Yamaha CM-500 to the K2, you can purchase the adapter used with the Proset-K2 - and wire the microphone configuration header just as for the Elecraft MH2 microphone - all pins jumper straight across and add the 5.6k bias resistor between mic jack pins 1 and 6.
I thought I had the part number for the adapter without the microphone, but I cannot find it, perhaps someone else will supply it. Of course, an adapter should not be difficult to build yourself with a Foster plug and 2 jacks (one for the microphone and another for the PTT input jack. 73, Don W3FPR On 2/18/2012 12:01 PM, Phil Yates wrote: > How would it match up to on the K2. > > Phil > G7BZD > > On Sat, Feb 18, 2012 at 4:56 PM, Dick Dievendorff<[email protected]>wrote: > >> You can plug the Yamaha CM500 microphone and headphone 3.5mm plugs directly >> into 3.5mm jacks on the back panel, and use the K3's SPKR+PH capability >> (which I have set up as PF1) to turn the speaker on and off.
