I am getting reports that it too many highs. They say it sounds like I am holding my nose when I talk. Any help is appreciated. 73 C.

If it has an amplifier in the base, you might consider bypassing the amplifier and running the microphone element's output directly to the rig's input.

It is a high-impedance crystal mike that has a very peaked response curve in the voice-frequency range.
