Doug, I expect you'll get a lot of differing opinions, but here's my
two cents. You don't need dual elements - just go with the HC-5 if
you want to use a headset (708 is probably a better sounding mic
though). You can accomplish the same thing as the HC-4 by adjusting
your Orion's TX EQ value with an additional 3-5dB toward the negative
side (e.g., -10dB for ragchewing and -13to-15dB for dx'ing - adjust be
ear while monitoring). You probably don't need a noise gate unless
you go with a very sensitive microphone, such as a condensor type.
Have someone record your tx audio and hear for yourself if there's a
lot of blower noise present.
