[Elecraft] Balanced Mic to Unbalanced Connection Follow Up Question

I have a microHAM microKEYER III that I use with my K3S.  I have a Heil
HM-10 Dual mic, which uses the Heil cable with an XLR connector, and a Heil
headset, which has a 3.5mm phone plug.  Both connect to the MKIII, which
connects to the rear mic jack on the K3S, and it's easy to switch between
the two using the microHAM router software.

All:

The K3S seems to work flawlessly with XLR cable connected to the rear panel
mic input as per the groups recommendations. I have pins 1 and 3 connected
to the sleeve of the 1/8" plug and pin 2 to the tip. I'm using a dynamic mic
so the bias is turned off. This setup works fine on the
KX3 as well.

If anyone is interested, I have a brand new Heil XLR cable for the K3S that
I won't be using.

Thanks,

Tony -K2MO
