I acquired an Astatic D-104 mic with the T-UP9 base. I wired it up to an eight pin mic connector per the Astatic website directions, however the mic drive is very sensitive. When I apply a little drive, the ALC is over driven. I have to set the drive nearly fully counterclockwise to prevent over driving the mic. If I sneak the drive up slightly, I over drive it. I soldered a 47ohm 1/2 watt resistor on the white audio wire, hoping that would fix the issue, but that didn't help. The mic drive is still nearly fully counterclockwise. I realize the Astatic is a high impedance mic and the '920 is designed for low impedance mics, but I know of many hams who use this mic with their modern rigs. Has anyone had a similar situation? 73, Tom, N8EUI
