[ICOM] IC-718

[Jerry Kessler]

Joe,

Since you desire for the audio passband to be tailored within the 
microphone and with a peak in the articulation range, why not adapt 
your existing mic's to the IC-718.  The Shure 444 is a high impedance 
mic so you will have to transform it to low impedance for the Icom or 
use a mic preamp to do the task.  The Heil XT-1 high-to-low impedance 
transformer should work.

Alternatively, find a Shure 444D with switchable hi-lo impedance and 
still have the tailored audio you want without resorting to impedance 
transformation.

The mic you have with the Heil HC-4 should work directly with the 
IC-718.  Or, consider taking the HC-4 element and using it to replace 
the standard Icom element in the hand mic, if that's feasible.

If using the existing mics, you must change the mic connector to one 
compatible with the IC-718.

For a communications quality headset consider the offerings by Arlan 
Communications (Dave Bottom, 
WI6R).  See:  http://www.arlancommunications.com/aboutTheCompany/. 
At the bottom of the home page, click on the link to finding a 
headset for your radio.  There is a specific headset-to-radio cable 
available for the IC-718.  While the Website indicates a 
communications style frequency response, call Dave Bottom to ensure 
that the audio passband he offers is tailored to your needs.  He 
appears to use an electret mic element to Icom.

Good luck.
