[AMRadio] Microphone Recommendation

[Ed Sieb]

I own several Shure 55S and E-V 664 and have used both quite successfully  
(in Hi-Z) on my BA transmitters: Apache, DX-100, and the Ranger.  
You have to modify the mic input circuits  by raising the grid-leak 
resistor to at least 5 megohms or more, and  change out the coupling caps.  
Doing those mods also makes the venerable D-104 sound excellent as well.
