[TenTec] Computer Headset Secured -- Now What?

[Bob McGraw - K4TAX]

I find it better to turn the hardware mike gain down, thus allowing one to 
run the DSP Mic gain in the 35% to 55% range.  Anything external such as an 
attenuator is an invite for potential RFI in the audio issue.  Also improves 
S/N ratio in the audio stages.

Also in my earlier post I mentioned using a 6.8K resistor and a 0.1 cap to 
block DC to the mike input to the radio.  If there's too much signal from 
the mike, increase the size of the resistor to 10K to 15K.  Everything is 
still the same physical size and will fit inside the 8 pin connector.    I 
agree with Jim, K9YC on the use of Switchcraft and Neutrik connectors.
