[Elecraft] K3 and YAMAHA CM-500

[ayoshida]

If CM-500 is connected to rear panel mic jack it works fine, however
if it is connected to front panel mic jack via conversion connector
I have a very low mic lebel with max mic level setting.
If CM-500 is connected to KX3 it works fine.

CM-500 mic plug to 8p plug connection in conversion connector is like
this.....
tip to pin-1
ring to pin 6 (K3 provides 8V regardless Bias ON/OFF)
sleeve to pin 7

I have another electret condenser hand mic. If this mic is connected to
K3 front panel mic jack it works fine.

If CM-500 is connected to K2 (where 5V is provided to pin 6 of mic jack)
using same
conversion connector it works fine.

Any suggestions please.
