[ICOM] Driving 746PRO/w dynamic mic

[Edward L. Dowdy]

I have an adapter I made for use with a 756PROII I had a couple years ago. 
It has a blocking cap in it. I was using the same mic with it. It worked 
fine. But having never had a 746PRO. I wasn't sure if it would require an 
electret to get enough drive. Thanks Gary.
